Abstract/OtherAbstract:
To establish a relationship between alterations in fatty acid metabolism, induced by sugar ingestion, and hypertension, we analyzed fatty acid composition of serum, platelets and aorta in rats which had 30% of sugar in their drinking water for 18-20 weeks, and became hypertensive, hypertriglyceridemic and hyperinsulinemic. The fatty acid composition in sugar-fed as compared with that from control rats was as follows: in serum phospholipids, triglycerides and cholesterol ester fractions, palmitic, palmitoleic, oleic and cis-11-eicosadecaenoic acids were present in a higher proportion. In serum phospholipid fraction linoleic and arachidonic acids were decreased and a significant increase was observed in the proportion of dihomo-gamma-linolenic acid. In the membrane phospholipids of platelets and aorta, higher proportions of palmitoleic and of oleic acids were observed. Differences in fatty acid composition of phospholipids between sugar-fed and control rats are consistent with altered membrane fluidity. Altered membrane function is a potential mechanism involved hypertension in rats in sugar-induced.
