REVIEW ARTICLE Specific features of glycogen metabolism in. Abstract. We previously found that exogenous GSH enhances mucosal GSH and promotes lipid hydroperoxide metabolism by rat small intestine (AW, T. Y., and M. W. WIlliams, 1992. The pentose phosphate pathway (PPP) is widely assumed to play a key role in both reductive biosynthesis and protection from oxidative stress because it is the major source of NADPH. However, little is known about the activity of the PPP in fatty liver, which is characterized by both oxidative stress and lipogenesis. This study was designed to.
