DL-Homocysteine is widely used in biochemical research, particularly in studies related to cardiovascular health and metabolic disorders. It serves as a key intermediate in methionine metabolism and is employed in assays to evaluate homocysteine metabolism pathways. Its presence in cell culture media helps investigate the effects of elevated homocysteine levels, which are associated with an increased risk of atherosclerosis, stroke, and thrombosis. It is also used in diagnostic applications to calibrate instruments and validate tests that measure homocysteine in blood samples. Additionally, DL-Homocysteine supports research into neurodegenerative diseases and fetal development, especially in understanding neural tube defects linked to abnormal homocysteine levels.
