Application:	Influence of DL methionine and sodium metabisulphite on the photostability of vitamin K1.: This study examines how DL methionine and sodium metabisulphite impact the photostability of vitamin K1, essential for understanding the interactions and stability of vitamin formulations (Ho and Wong, 1998 ). Amino acid polymers for biomedical applications. I. Permeability properties of L-leucine DL-methionine copolymers.: This research explores the permeability properties of copolymers made from L-leucine and DL-methionine, which have significant implications for biomedical applications like drug delivery systems (Martin, May, and McMahon, 1971 ). ESR measurement of short-lived free radicals obtained by addition of OH to DL-methionine.: This article describes the electron spin resonance (ESR) measurements of short-lived free radicals produced when hydroxyl groups are added to DL-methionine, offering insights into the radical chemistry of amino acids (Bürk and Schoffa, 1969 ).
General description:	DL-Methionine is a sulfur-containing amino acid mainly used as a dietary supplement for poultry. It is a key precursor for synthesizing carnitine and creatine in the body.
