Abstract
The growth and liver components of young rats fed on egg albumin reacted with ethyl linoleate (2 : 1, w/w, at 50°C and RH 80.4% for 7 days) were compared with those fed on unreacted albumin.
At a 10% protein level, reacted albumin depressed the growth and caused an increase in liver glycogen and a decrease in liver nitrogen and lipids. The decrease in liver lipids was mainly due to that of triglyceride. On the other hand, the concentration of plasma lipid components increased.
Fatty acid analyses of liver triglyceride of rats fed reacted albumin revealed lower percentage ofpalmitoleic acid and higher percentage of stearic and linoleic acids. In hepatic lecithin, percentage of arachidonic or oleic acids was decreased.
At a 20% protein level, there were on differences in the growth and liver lipid components between two groups of rats, except the contents of glycogen and nitrogen in the liver.
These data indicate that albumin reacted with the oxidized lipid influences, in particular at a low dietary level, on the growth and liver components of young rats.
