Effects of Browning Products of Glucosamine on Serum and Liver Lipids of Rats

Abstract

Rats fed on a purified diet (corn starch 50.8%, case in 23.3%, cellulose 3.0%, mineral 14.0 %, moisture 8.9% and lard 10.0%) were given glucosamine-HCl (GA-HCL), free gluco samine (FGA), browning product of glucosamine (BGA) (0.49/rat/week) as drinking water f or 3 weeks, and total cholesterol (T-Chol) and triglyceride (TG) as well as fatty aci d compositions in serum and liver were an alyzed. The results obtained are as foll ows: l) Body weight gain was lower for the FGA and BGA groups than for the control an d GA-HCl groups, but total lipid contents and weight of liver were comparable amon g the groups. 2) Concentrations of serum T-Chol and TG were lower in the FGA and BGA groups. 3) BGA lowered the proportion of total polyenoic acids in the total lipi d fraction of serum and liver.
