Incorporation of Acetate-1-C¹⁴ into Fatty Acids by Whole Blood from the Bovine

Department of Dairy Science, University of Illinois, Urbana

ABSTRACT

Studies with human blood have shown that acetate-1-C¹⁴ is incorporated into lipids and that leukocytes and platelets are primarily responsible for the synthesis (4, 5, 7, 8, 12). Formation of fatty acids by leukocytes accounts for approximately two-thirds of the C¹⁴ incorporation (5, 8, 12). Fatty acid synthesis by erythrocytes is very limited and appears to occur only in immature cells (8, 10, 11). Marks et al. (8) found that about two-thirds of the incorporation of acetate-1-C¹⁴ by leukocytes of human blood was into neutral lipids and about one-third into phospholipds. Platelets had an incorporation ratio of about 60:40 into neutral and phospholipids, respectively. The greatest per cent of acetate-1-C¹⁴ activity resided in the long-chain fatty acid fraction (5, 10). Garton (4) concluded that palmitic acid is the major higher fatty acid formed from the acetate by blood. No similar studies with ruminant blood are known to the authors.
