  • The effect appears to be entirely due to restriction of the amino acid methionine, which is required to initiate protein synthesis.
  • This particular enzyme catalyses serine into cysteine which is eventually converted to the essential amino acid methionine.
  • It can also detect deficiencies in a nutritionally incomplete diet if the essential amino acid methionine is experimentally removed from its food.
  • The amino acid methionine can also be used effectively as an antidote for NAPQI toxicity.
  • The amino acid methionine is produced by addition of methanethiol followed by the Strecker synthesis.
  • Methionine sulfoxide forms from the amino acid methionine and its accumulation is associated with aging.
  • Tahini is an excellent source of copper, manganese and the amino acid methionine.
  • Also, most nascent polypeptides start with the amino acid methionine because the "start" n mRNA also codes for this amino acid.
  • It is produced industrially from propylene and mainly used as a biocide and a building block to other chemical compounds, such as the amino acid methionine.
  • Dairy-herd milk production may be limited by the amino acid methionine; therefore, the amino acid is included in cattle rations to provide a well-balanced diet.
  • Hypermethioninemia is an excess of the amino acid methionine, in the blood.
  • In contrast, cassava leaves are a good source of protein (rich in lysine) but deficient in the amino acid methionine and possibly tryptophan.
  • Critics of a vegan diet insist that legumes contain relatively low quantities of the essential amino acid methionine, as compared to whole eggs, dairy products, or meat.
  • Thioethers are important in biology, notably in the amino acid methionine and the cofactor biotin.
  • Brevibacteria are considered a major cause of foot odor because they ingest dead skin on the feet and, in the process, convert amino acid methionine into methanethiol, which has a sulfuric aroma.
  • Some studies on rats have indicated the biological value of soy protein isolates is comparable to animal proteins such as casein if enriched with the sulfur-containing amino acid methionine.
  • Homocystinuria is an inherited disorder involving the metabolism of the amino acid methionine leading to the accumulation of homocysteine.
  • In red wines, some strains metabolize the amino acid methionine into a derivative of propionic acid that tends to produce roasted aroma and chocolate notes.
  • The amino acid methionine is prone to oxidation, but oxidized methionine can be reversible.
  • It inhibits the conversion of the sulfur amino acid methionine to cysteine.
