| 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. |
| Definition |
ChEBI: Homocysteine with L configuration. |
| 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 ( |
