Microsomal lipids, absorbance

Absorbance patterns of microsomal lipids, CD diet and dietary fats, 331... [Pg.360]

Grapes, wine and other berry products are acidic, and the anthocyanins are in the flavylium form. A hypothesis that the anthocyanins may be pH-transformed into their carbinol pseudo-base and quinoidal base, or the chalcone, in the intestine and blood system during digestion has been proposed by Lapidot et al. (1999). These compounds have been shown to have antioxidant activity and are also most likely absorbed from the gut into the blood system. The pseudo-base and the quinoidal base of malvidin and malvidin-3-glucoside remained as very effective antioxidants, both when tested by a linoleate-oxidizing assay and by a microsomal lipid peroxidation assay. [Pg.117]

Enzymic processes in the enterocyte which handle a number of lipid species other than triglycerides are also known to be influenced by bile salts. For example, it has been postulated that pancreatic cholesterol esterase is absorbed by the mucosal cells and catalyzes the esterification of cholesterol in the cell [87]. This postulate has been challenged by Watt and Simmonds [88] although Bhat and Brockman [30] recently produced evidence for the importance of pancreatic cholesterol esterase for transport across the enterocyte membrane. Another enzyme, acyl-CoA cholesterol acyltransfera.se (ACAT) of microsomal origin, has been ascribed a major role in mucosal esterification of cholesterol [89], Unlike pancreatic cholesterol esterase, this enzyme is inhibited by taurocholate in vitro. [Pg.418]
