Methionine

Methionine (Methionine) is an essential sulfur-containing amino acid that cannot be synthesized by the body itself and must be ingested through the diet. It is not only the key starting amino acid of protein biosynthesis, but also plays an important role in the initiation of protein synthesis in the translation process of all eukaryotes. It also participates in a variety of key physiological functions, including methylation reaction, antioxidant defense (as a precursor of glutathione synthesis), lipid metabolism regulation and liver detoxification process. In addition, methionine is a direct precursor of the important methyl donor S-adenosylmethionine (SAMe) in the body and plays a central role in the epigenetic modification of DNA, RNA and proteins. In the field of nutrition, methionine is often used to optimize the amino acid balance of feed and improve animal growth performance and immunity; in medicine and health products, it is also widely used to protect liver, improve fatty liver, relieve chronic fatigue and support The nervous system health and so on.
