| | L-HOMOCYSTEINE Usage And Synthesis |
| Chemical Properties | Colourless or nearly colourless solid | | Uses | L-Homocysteine is the hydrolysis product of adenosine (A280400), a purine nucleoside. Metabolic fate of L-Homocysteine is converted back to L-Methionine( M260440) via tetrahydrofolate. | | Uses | L-homocysteine has been used as a supplement in cell culture media. | | Definition | ChEBI: Homocysteine with L configuration. | | General Description | L-homocysteine is used to diagnose homocystinuria. | | Biochem/physiol Actions | Elevated homocysteine levels in plasma and tissue are associated with brain atrophy in Alzheimer′s disease as well as in healthy eldery subjects. Increased homocysteine is due to deficiencies in vitamin B status, specifically folate, B6 and B12 vitamins, which act as cofactors for enzymes involved in homocysteine metabolism. | | Purification Methods | Crystallise L-homocysteine from aqueous EtOH. All operations should be carried out under N2 as the thiol readily oxidizes in air. The acid (3g) is dissolved in freshly boiled H2O ( |
