Vitamin C inhibits lipid oxidation in human high-density lipoproteins
November 24th, 2003
Vitamin C inhibits lipid oxidation in human high-density lipoproteins (HDL). "HDL are susceptible to oxidation, which affects their cardioprotective properties," researchers in Chicago explained. "Although several studies have reported inhibition of HDL oxidation by vitamin E, none has determined the potential protective effect of vitamin C, another important blood antioxidant." To rectify this, R.J. Hillstrom and colleagues at Midwestern University "investigated whether vitamin C protects HDL from oxidation by incubating HDL (0.2 g of protein/L) at 37 degrees C with cupric (CU2+) ions (10 micromol/L) in the absence (control) or presence of vitamin...
