Chemical Properties

White powder

Uses

Increased levels lead to hyperhomocysteinemia; a cardiovascular risk factor in prediction of coronary heart disease as well as being associated with congenital birth defects, pregnancy complications and cancer.

Purification Methods

The acid (3g) is dissolved in freshly boiled H2O (30mL) under N2, cooled under N2 (all operations should be under N2), absolute EtOH (100mL) is added, the acid is filtered off, and a second crop is obtained by diluting the filtrate to 500mL with absolute EtOH, kept overnight in a refrigerator, filtered, washed with EtOH and dried in a vacuum. The D(R,R)-form has similar properties but is –ve in M HCl and +ve in H2O.
