:(±)-Homocysteine
Description:
(±)-Homocysteine is a sulfur-containing amino acid that plays a crucial role in the metabolism of methionine, an essential amino acid. It is a non-proteinogenic amino acid, meaning it is not incorporated into proteins but is involved in various biochemical processes. Homocysteine exists in several forms, including free homocysteine and its derivatives, such as homocysteine thiolactone. The compound is characterized by its chiral nature, having two enantiomers, which can influence its biological activity. Elevated levels of homocysteine in the blood are associated with an increased risk of cardiovascular diseases, as it can lead to endothelial dysfunction and promote atherosclerosis. Homocysteine is also involved in the methylation cycle, where it can be remethylated to form methionine or converted to cysteine through transsulfuration. Its metabolism is dependent on various vitamins, particularly B6, B12, and folate. Monitoring homocysteine levels can be important in clinical settings, particularly for assessing cardiovascular risk and nutritional status.

CAS:<p>DL-Homocysteine is a sulfur-containing amino acid that is essential for the synthesis of methionine, and is an intermediate in the metabolism of L-methionine. DL-homocysteine has been shown to cause cardiac infarction in rats by inhibiting mitochondrial functions. This amino acid also inhibits the activity of enzymes that regulate homocysteine levels, such as cystathione beta-synthase and cystathione gamma-lyase. DL-homocysteine can be used as a fluorescent probe for detecting proteins involved in apoptosis. It also has proapoptotic effects on cells, causing them to undergo apoptosis.</p>Formula:C4H9NO2SPurity:Min. 95%Color and Shape:PowderMolecular weight:135.19 g/mol
