Notes: Creatine is a derivative of the amino acid glycine.{72033} It is produced from glycine and L-arginine by arginine:glycine amidinotransferase (AGAT) and guanidinoacetate N-methyltransferase (GAMT) via a guanidinoacetate intermediate. Creatine circulates in the blood and enters tissues via the creatine transporter. In tissues, it is phosphorylated to creatine phosphate (Item Nos. 35598 / 37803), which is used as a reservoir of phosphoryl groups that can be transferred to ATP for the first few seconds of energy consumption, particularly in high-energy consumption tissues such as the brain and skeletal muscle.{72034} Decreased brain levels of creatine are associated with inborn errors of creatine metabolism characterized by deficiency of AGAT, GAMT, or the creatine transporter.{72033}
