Methionine is one of the common sulfur-containing amino acids. Methionine is a common methyl-group donor to various substrates, such as creatine, epinephrine, ergosterol, and choline.
L-Methionine is used as an essential amino acid for human development and therapeutically acts as an antidote for acetaminophen poisoning. It serves as a chelating agent for heavy metals, as a flavoring agent and nutritional supplement for foods. It acts as a feed additive, vegetable oil enrichment and as a single cell protein. In addition to this, it is used as a hepatoprotectant and also acts as a lipotropic agent and prevents excess fat buildup in the liver.
L-Methionine is the L-isomer of methionine, an essential amino acid for human development. Methionine is important in many functions, including acting as a hepatoprotectant, an acetominophen poisoning antidote, and a urinary acidifier. It is also a chelating agent for heavy metals.
