A sulfur containing essential amino acid that is important in many body functions. It is a chelating agent for heavy metals.
A sulfur-containing essential amino acid.
An essential amino acid; one of the three containing sulphur; cystine and cysteine are the other two. Cystine and cysteine are not essential, but can only be made from methionine, and therefore the requirement for methionine is lower if there is an adequate intake of cysteine.
An essential amino acid; furnishes (to organism) both labile methyl groups and sulfur necessary for normal metabolism.
A sulfur-containing essential amino acid.
One of the essential amino acids containing sulphur, which is frequently marginal or deficient when the proteins are entirely of vegetarian origin.
An essential amino acid. Methionine serves as an essential methyl donor for the synthesis of many compounds. Sulfur is conserved through its interconversion to cysteine.
Methionine is an essential amino acid containing sulfur that is needed for production of proteins. Methionine serves as a methyl group donor in many reactions and is needed for the synthesis of the nonessential amino acid cysteine. A related chemical, S-adenosyl methionine, has become a popular dietary supplement in the past few years and is described briefly in a separate entry.
Essential (not produced by the body, required in the diet) amino acid.
An indispensable amino acids that contains sulphur, necessary for normal growth in infants and to maintain nitrogen balance in adults.
