Red blood cell membrane composition following diet manipulation in the cow. II: phospholipid fatty acid distribution and physico-chemical characteristics of membrane and its constituents

In the research were analyzed in the cow: the fatty acid distribution of phospholipids isolated from RBC membrane ; the thermotropic behaviour of membrane and of total lipids and phospholipids extracted from the membranes ; the physical configuration measured by 31 P NMR. The animals were fed on with different types and amount of fats; moreover some of the fatty material was administered as calcium soaps
