説明

Diets containing different proteins at 20% level were fed to groups of young adult rats which had been trained to consume their daily requirement during 1.5 hr by spaced-feeding.<BR>On the first one hour after withdrawal of food, the contents of the small intestinal lumen were collected and analyzed for nitrogen distribution.<BR>When the diet containing 20% egg albumin was given, greater amount of protein was accumulated as compared to casein, gelatin, zein or wheat gluten. The accnmulation was accompanied with a protein fraction (TE) which was extractable with ethanol after trichloroacetic acid precipitation.<BR>Electrophoresis of TE showed that at least one of the constituents appeared to be serum albumin.<BR>Although no obvious correlation has been commonly noted between dietary egg albumin and the metabolism of serum albumin, these findings suggest that such a high accumulation of protein may largely be derived from endogenous sources than from dietary egg albumin per se.
