L-Methionine powder
L-Methionine is an essential sulfur-containing amino acid that plays irreplaceable roles in protein synthesis, metabolic regulation, and physiological function maintenance in humans and animals. As one of the nine essential amino acids for humans, it cannot be synthesized endogenously and must be obtained through dietary intake or nutritional supplements. Key Distinctions from D-Methionine of L-Methionine L-Methionine is the naturally occurring, biologically active isomer, while D-Methionine (its enantiomer) has no biological activity in humans and animals, as it cannot be incorporated into proteins or participate in metabolic reactions. Industrial production of L-Methionine primarily relies on chemical synthesis (racemic mixture resolution) or biofermentation, with the latter gaining prominence due to its green and efficient characteristics.
