l-Methionine

Description:

L-Methionine is an essential amino acid that plays a crucial role in various biological processes. It is classified as a sulfur-containing amino acid, characterized by the presence of a thioether group in its structure. L-Methionine is a building block for proteins and is vital for the synthesis of other important biomolecules, including cysteine and taurine. It is also involved in the methylation process, contributing to the formation of S-adenosylmethionine (SAM), a key methyl donor in numerous biochemical reactions. This amino acid is typically found in high-protein foods such as meat, fish, dairy products, and certain nuts and seeds. In terms of physical properties, L-Methionine is a white, crystalline powder that is soluble in water and has a slightly bitter taste. It is often used in dietary supplements and animal feed to promote growth and health. Additionally, L-Methionine has antioxidant properties, helping to protect cells from oxidative stress. Its CAS number is 63-68-3, which uniquely identifies this compound in chemical databases.

L-Methionine

CAS: 63-68-3

L-Methionine is a non-essential amino acid that belongs to the group of essential amino acids. It is a major constituent of proteins and is used in the metabolism of lipids, carbohydrates, and nucleic acids. Methionine is also involved in the synthesis of cysteine, which is an important antioxidant. L-Methionine can be found in many foods such as eggs, dairy products, fish, poultry, soybean products, peanuts, beans and seeds. Studies have shown that L-methionine has effects on liver function and may be useful for prevention or treatment of liver disorders such as primary sclerosing cholangitis (PSC). This compound also plays a role in the formation of body tissues and cells. L-Methionine has been shown to increase glutathione levels which are important for detoxification reactions and protection against oxidative stress. It also helps regulate calcium metabolism by reducing calcium absorption from food and increasing excretion via
