Methionine, an organic compound, is constructiveEssential amino acidsOne of them, the molecular formula is C5H11O2NS, which has optical rotation and participatesProtein synthesis
Because it cannot be generated in the body, it must be obtained from the outside. If methionine is deficient, protein synthesis in the body is blocked, causing damage to the body. Excessive oxidation of membrane lipids caused by oxygen radicals in the body is responsible for a variety of damage to the body. Lipid peroxideswill damage the primary andSecondary lysosomesmembranes that allow lysosomes to contain as hydrolyzedAcid phosphataseRelease it out on the cells andMitochondrial membranemethionine fights these damages through a variety of pathways.

MethionineIt is mainly used as a nutritional supplement. It has the same physiological effect as L-type methionine, but ** is low (L-form is made from DL-type), so DL-methionine is generally used. It is a restricted amino acid in plant foods such as oats, rye, rice, corn, wheat, peanut flour, soybeans, potatoes, and spinach. Add to the above foods to improve amino acid balance. The amount required varies with cystine intake.
Methionine alsoCan be used as a spice.
