Lcysteic
Lcysteic is a non-proteinogenic amino acid that is derived from cysteine. It is formed by the oxidation of the thiol group of cysteine to a sulfonic acid group. This oxidation can occur in biological systems, particularly in conditions of oxidative stress. Lcysteic is not incorporated into proteins during translation like its parent amino acid, cysteine.
The presence of Lcysteic has been detected in various biological samples, including urine and plasma. Its concentration
The biological significance of Lcysteic is still an active area of research. It is thought to be
