In the previous paper, we reported that browning products of glucosamine (BGA) lowered the proportion of the total polyenoic acids in total lipids of serum and liver of rats. In this paper, the fatty acid composition of serum and liver lipid classes in rats administered free glucosamine (FGA) and BGA were examined by means of thin layer chromatography (TLC) and gas liquid chromatography (GLC). The results obtained were as follows; (1) Serum and liver lipid could be separated into seven classes (sterol esters, triacylglycerines, free fatty acids, 1.2-, 1.3-diacylglycerines, sterols and compound lipids). (2) Fifteen to twenty fatty acids were found in the serum and liver lipid; the major fatty acids were C 16:0, C 18:0, C 18:1, C 18:2 and C 20:4. (3) Total polyenoic acid content in serum of the rats administered FGA was higher than that of the animals administered BGA.
