      Product Detail  



    Methionine, an organic compound, is one of the essential amino acids that make up the human body, with the molecular formula C5H11O2NS, has a cyclic nature and is involved in protein synthesis.
    Because it cannot be produced in the body itself, it must be obtained externally. If methionine is deficient it will lead to the blockage of protein synthesis in the body, causing damage to the organism. Excessive oxidation of membrane lipids caused by oxygen free radicals in the body is responsible for many types of damage to the organism. Lipid peroxidation damages primary and secondary lysosomal membranes, releasing the acid phosphatase contained in the lysosomes as a hydrolytic enzyme, causing damage to important organelles such as cellular and mitochondrial membranes, and methionine fights against these damages through a variety of pathways.
