L-pyroglutamic acid is an amino acid which is prevalent in all living organisms. It is not an essential amino acid, as it can be produced endogenously in humans, usually from L-proline or L-glutamate as a dietary source. L-pyroglutamic acid bears the same 2-pyrrolidinone skeletal structure common to drugs of the racetam family, and is structurally related to fasoracetam, which itself is an amide of pyroglutamic acid (L-pyroglutamic acid N,N-piperidide, specifically).
This compound is not for human consumption, and its sale is strictly intended for research purposes only.
