Nonalcoholic components in wine reduce low density lipoprotein cholesterol in normocholesterolemic rats.

abstract：:Neuronal membranes are highly enriched with docosahexaenoic acid (22:6n-3), and its content can be altered by ethanol consumption. We have previously reported that the 22:6n-3 status in membrane affects the biosynthesis of phosphatidylserine (PS), a phospholipid class which contains an exceptionally high proportion of...
