Common NameCreatine
DescriptionCreatine, also known as cosmocair C 100 or krebiozon, belongs to the class of organic compounds known as alpha amino acids and derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. Creatine is a drug which is used for nutritional supplementation, also for treating dietary shortage or imbalance. Creatine is a very strong basic compound (based on its pKa). Creatine exists in all living organisms, ranging from bacteria to humans. Within humans, creatine participates in a number of enzymatic reactions. In particular, S-adenosylhomocysteine and creatine can be biosynthesized from S-adenosylmethionine and guanidoacetic acid; which is mediated by the enzyme guanidinoacetate N-methyltransferase. In addition, creatine can be converted into phosphocreatine through the action of the enzyme creatine kinase b-type. In humans, creatine is involved in the metabolic disorder called hyperornithinemia with gyrate atrophy (hoga). Outside of the human body, Creatine is found, on average, in the highest concentration within milk (cow). Creatine has also been detected, but not quantified in, several different foods, such as mulberries, beans, rubus (blackberry, raspberry), highbush blueberries, and broccoli. This could make creatine a potential biomarker for the consumption of these foods. Creatine is a potentially toxic compound. A glycine derivative having methyl and amidino groups attached to the nitrogen.
