What are two the two effects of polyunsaturated fats?

Answer 1

We can consider two effects of polyunsaturated fatty acids: First, as vital components of biological membranes. Fatty acids are, beside proteins, the most important components of biological membranes (i.e., plasma membrane and organelles). The more unsaturated the fatty acid is, the more water-permeable is, and also to the phenomenon called "membrane fluidity". We can find polyunsaturated fatty acids in digestive system, arteries and liver. In this case, polyunsaturated fatty acids act as structural components of a tissues and organs highly specialized of the physiological systems; and second, the metabolism of fatty acids (beta oxidation), and in particular of polyunsaturated ones, produces a high amount of acetyl-coA, a vital molecule of the citric acid cycle and eventually for the synthesis of ATP.
