The Uses of 1-Methyl-L-histidine

The urinary 1- and 3-methylhistidine (1- and 3-MH) metabolites as potential biomarkers of skeletal muscle toxicity. These metabolites were highly correlated to sex-, dose-, and time-dependent developm ent of cerivastatin-induced myotoxicity. Natural but non-proteinogenic amino acid; employed as index of muscle protein breakdown.

Definition

ChEBI: N(tele)-methyl-L-histidine is a L-histidine derivative in which the methyl group is at N(tele)-position. It has a role as a human metabolite. It is a L-histidine derivative and a non-proteinogenic L-alpha-amino acid. It is a tautomer of a N(tele)-methyl-L-histidine zwitterion.
