Antioxidant activity of 6-phosphatidyl-L-ascorbic acid.
The antioxidant activity of 6-phosphatidyl-L-ascorbic acid was investigated in a homogeneous solution and a liposomal suspension. In an apolar solvent, one molecule of 6-phosphatidyl-L-ascorbic acid could trap one peroxyl radical. When 6-phosphatidyl-L-ascorbic acid was included in multilamellar liposomes of egg yolk phosphatidylcholine, it could retard more effectively the aqueous peroxyl-induced peroxidation of phosphatidylcholine than L-ascorbic acid.
