CAS 59-51-8

(±)-Methionine

Description:

(±)-Methionine, with the CAS number 59-51-8, 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. Methionine is a chiral molecule, existing in two enantiomeric forms, which are mirror images of each other; however, the (±) designation indicates that this substance is a racemic mixture of both enantiomers. This amino acid is vital for protein synthesis and serves as a precursor for other important biomolecules, including cysteine and taurine. Methionine is also involved in methylation processes, contributing to the regulation of gene expression and the metabolism of various compounds. In terms of physical properties, it is typically a white, crystalline solid that is soluble in water. Methionine is commonly found in various dietary sources, particularly in protein-rich foods such as meat, fish, and dairy products, making it an important component of human nutrition.

DL-Methionine is a naturally occurring amino acid that is essential for healthy protein synthesis. Methionine can be synthesized by the human body, but it must be consumed through diet. DL-Methionine has been shown to have anti-obesity properties in vitro and in vivo models. It also helps maintain normal levels of calcium and pantothenate in the blood and supports the function of the immune system. DL-Methionine may also have effects on locomotor activity, body mass index, and peptide hormones.
