Everything below concerns Creatine. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2025-08-12. Where a claim depends on a specific study, the study is described rather than over-claimed.
Creatine is synthesized endogenously in humans, mainly in the liver, kidney, and pancreas, from the amino acids arginine, glycine, and methionine. Skeletal muscle stores much of the body's creatine, where it participates in the phosphocreatine system that buffers adenosine triphosphate during short, intense contractions. Dietary sources include meat and fish, so omnivorous diets provide additional creatine beyond endogenous production. Supplemental creatine monohydrate supplies the same molecule found in food and tissues, not a distinct drug or hormone. Research interest centers on its role in cellular energy transfer and its effects on muscle and other tissues.
Several creatine forms are sold, including monohydrate, anhydrous, hydrochloride, nitrate, citrate, and blends. Once dissolved, these forms deliver creatine, but they differ in molar mass, solubility, counterions, and water content. Creatine monohydrate has the largest body of published human data among these forms. Questions remain about whether any alternative form offers meaningful advantages in absorption, tolerability, or tissue uptake under practical conditions. The hydrate form's lower creatine content by mass is a compositional fact, not a statement about effectiveness.
Commercial creatine monohydrate is typically a white to off-white powder with low odor. It is commonly sold as a fine powder, micronized powder, or larger crystals, but these are physical forms of the same chemical. Purity grades vary, and products may contain small amounts of related substances such as creatinine, dicyandiamide, or moisture. The monohydrate is often selected for supplements and research because its production is well established and its behavior in water is predictable. Analytical certificates usually report assay, loss on drying, and heavy metals.
Creatine monohydrate is a crystalline compound formed from creatine and one water molecule in its solid lattice. Creatine itself is a nitrogen-containing organic acid involved in energy transfer in muscle and other tissues. The monohydrate form is the most common solid form used in research and commercial products because it is stable and easy to handle. The term "monohydrate" refers to the fixed one-to-one ratio of water to creatine in the crystal, not to moisture content. This distinction matters when comparing labels or calculating creatine content.
In chemical terms, creatine monohydrate is often described as N-(aminoiminomethyl)-N-methylglycine monohydrate, though nomenclature varies. Its solid state consists of zwitterionic creatine molecules linked with water through hydrogen bonding. The compound dissolves in water, but dissolution rate depends on particle size, temperature, and agitation. Once dissolved, the hydrate water becomes part of the solvent, leaving free creatine in solution. The monohydrate is not the same as creatine anhydrous, which lacks the water of crystallization and has a higher creatine fraction by mass.

=== P53 and p73 === p53 and p73 are tumor suppressor proteins and their degradation is tightly regulated by ubiquitination. Recently it was shown that their degradation can also occur via an ubiquitin-independent process; NQO1 blocks p53 and p73 degradation in the presence of NADH and protects them from 20S proteasomal degradation. This protein-protein interaction between p53 and NQO1 was non-catalytic.
Afterwards, Adler takes extended time away from work, eventually revealing to Eric that he has a malignant brain tumor, and may not live longer than a year. As Pierpoint faces a debt crisis stemming from its ESG pivot, Adler clashes with senior leadership, particularly CFO Wilhelmina Fassbinder, over a potential sale of the firm, and brokers a meeting with Mitsubishi executives. Eric, realizing he needs to break free from Adler's influence, exploits Adler's illness during the meeting by gaslighting him into believing he overlooked a major error in the deal sheet. Adler has a breakdown and reveals his prognosis to the room; Eric escorts him out, and Adler realizes Eric betrayed him. Six months later, Adler has died, with Pierpoint organizing his memorial.
== Occurrence == Carotenoids are essential for animal health and functioning, but animals cannot produce them. Animals obtain carotenoids from their diet, with herbivores sourcing them from plants or algae, and carnivores, in turn, sourcing them from herbivores. Meso-zeaxanthin is not present in plants, except for marine species. Originally, it was suggested that meso-zeaxanthin present in humans and other vertebrates was non-dietary in origin, instead being biosynthesized in the macula (the central part of the retina) from retinal lutein (another xanthophyll carotenoid found in the human diet); this work has since been refuted. Consistent with work by Maoka et al. in 1986, Nolan et al. showed that meso-zeaxanthin is present in the skin of trout, sardine and salmon, and in the flesh of trout. In a subsequent publication, Nolan's group detected and quantified the three stereoisomers of zeaxanthin, including meso-zeaxanthin, in the flesh of two different trout species, which was the first report of concentrations of meso-zeaxanthin in habitually consumed food. Prior to this research, a publication from Khachick et al. (2002) reported that liver from Japanese quail (Coturnix japonica) and frog plasma contain meso-zeaxanthin. Meso-zeaxanthin may be generated from other carotenoids consumed by animals, as carotenoids can be interconverted for functional reasons. For example, it has been suggested that meso-zeaxanthin of trout integuments is derived from astaxanthin, and meso-zeaxanthin in primates is derived at least in part from lutein.
=== LNS in females === While carrier females are generally an asymptomatic condition, they do experience an increase in uric acid excretion, and some may develop symptoms of hyperuricemia, and experience gout in their later years. Testing in this context has no clinical consequence, but it may reveal the possibility of transmitting the trait to male children. Women may also require testing if a male child develops LNS. In this instance, a negative test means the son's disease is the result of a new mutation, and the risk in siblings is not increased. Females who carry one copy of the defective gene are carriers with a 50% chance of passing the disease on to their sons. In order for a female to be affected, she would need to have two copies of the mutated gene, one of which would be inherited from her father. Males affected with LNS do not usually have children due to the debilitating effects of the disease. It is possible for a female to inherit an X chromosome from her unaffected father, who carries a new mutation of the HGPRT gene. Under these circumstances, a girl could be born with LNS, and though there are a few reports of this happening, it is very rare. The overwhelming majority of patients with LNS are male.

Concerning females who have the condition congenital adrenal hyperplasia, the largest group requiring surgical genital correction, researcher Atilla Şenaylı stated, "The main expectations for the operations are to create a normal female anatomy, with minimal complications and improvement of life quality". Şenaylı added that "[c]osmesis, structural integrity, the coital capacity of the vagina, and absence of pain during sexual activity are the parameters to be judged by the surgeon". (Cosmesis usually refers to the surgical correction of a disfiguring defect.) He stated that although "expectations can be standardized within these few parameters, operative techniques have not yet become homogeneous. Investigators have preferred different operations for different ages of patients". Gender assessment and surgical treatment are the two main steps in intersex operations. "The first treatments for clitoromegaly were simply resection of the clitoris. Later, it was understood that the clitoris glans and sensory input are important to facilitate orgasm", stated Atilla. The clitoral glans' epithelium "has high cutaneous sensitivity, which is important in sexual responses", and it is because of this that "recession clitoroplasty was later devised as an alternative, but reduction clitoroplasty is the method currently performed".
== History == Some of the first examples of PPy were reported in 1919 by Angeli and Pieroni, who reported the formation of pyrrole blacks from pyrrole magnesium bromide. Since then pyrrole oxidation reaction has been studied and reported in scientific literature. Work on conductive polymers including polypyrrole, polythiophene, polyaniline, and polyacetylene was awarded the Nobel Prize in Chemistry in 2000 to Alan J. Heeger, Alan G. MacDiarmid and Hideki Shirakawa.
On 7 November, the National Guard warned of ceasefire violations such as the bombing of civilian homes, the National Guard also shot down a drone loaded with explosives. The statement added that there were clashes in Rasas. On 13 November, heavy fighting broke out in Al-Majdal, following the infiltration of Syrian government forces and drone attacks, prompting the National Guard to send reinforcements to the border. That same day, Syrian government forces attacked the Suwayda–Taara road, The skirmishes, which were the heaviest in months, were noticeable for the use of "drones, mortars, and heavy machine guns" by both sides. The "towns of Wolgha, Tal al-Aqra, Tal Hadid and al-Mazraa" were targeted by what the Syrian government called "outlaw forces". On 19 November, Benjamin Netanyahu visited the areas occupied by Israel in the invasion of Syria, where he declared he would "protect the Druze allies in Jabal al-Druze". On 20 November, a gang kidnapped five Druze people from Suwayda: Talal Dheeb, Reem Dheeb, Mahmouda Quraisha, Ilham Abu Zein Al-Din and Rafi Habib, who were released in Al-Musayfirah, Daraa Governorate. The gang leader was arrested. The kidnapped people were residents of As-Sawra as-Saghira. Hussam al-Tahhan stated that "the operation took place after careful monitoring on the ground and intensive surveillance and investigations".

It is the hydrated crystalline form of creatine, containing one bound water molecule per creatine unit. The compound is commonly used as a nutritional ingredient and as a research material.
Yes, endogenous synthesis occurs mainly in the liver, kidney, and pancreas. Meat and fish also contribute creatine to the diet.
Other forms contain creatine paired with different counterions or lacking water, so their mass and solubility differ. After dissolution, creatine itself is the shared active molecule.
It is a solid form of creatine that contains one water molecule per creatine molecule in the crystal lattice. The hydrate water is part of the crystal structure rather than loose moisture. The term is often used for the common crystalline powder grade.
