GAA Fundamentals
Guanidinoacetic acid (also known as glycocyamine or betacyamine) is a normal constituent of human blood, urine, and breast milk.
Being a natural amino acid derivative and a metabolite in the urea cycle, GAA also appears as an intermediate in metabolic pathways of several amino acids, including glycine, serine and arginine. GAA is direct precursor of creatine, a key substrate for cellular energy.
- CAS Registry # 362-97-6
- PubChem CID 763
- Chemical formula C3H7N3O2
- Molar mass 117.1 g/mol
The natural daily turnover of GAA is balanced between endogenous production and kidney excretion; only a minimal amount of GAA is available from food sources (e.g. 10 mg of GAA per kg of meat).
