Effects of dietary fats on fatty acid composition and delta 5 desaturase in normal and diabetic rats.

abstract：:Acyl-CoA cholesterol acyltransferase (ACAT) (EC 2.3.1.26) in the yolk sac membrane of chicken eggs plays an important role in the transport of lipids, which serve as both structural components and as an energy source during embryogenesis. ACAT from the yolk sac membrane of chicken eggs 16 d after fertilization has hig...
