説明

A quantitative fractionation method of muscle protein was presented. Muscles from the adult rats fed a normal, a tryptophan-free and a protein-free diets separately for 4 weeks were fractionated by this method. The effects on the composition of the muscle protein fractions were different between the tryptophan-free and the protein-free diets. The decreases of non-protein nitrogen and sarcoplasmic protein by both deficient diets were greater than that of total muscle nitrogen, whereas those of actin, myosin and stroma were smaller. This shows the presence of the different dietary effects on the constituent proteins of muscle.
