Abstract
The amount of total muscles and their protein content of albino rats fed on protein-free diet for about two months decreased considerably, as compared with those fed on normal diet.
The chemical properties and some constitutional amino acid contents of actomyosin extracted from the leg muscles of rats were investigated.
Relative viscosity, ATPase activity, and some constitutional amino acid contents of actomyosin-S, which was extracted from the muscles of rats fed on protein-free diet by short-period extraction, showed a slight difference from those of the protein from control rats, whereas those of actomyosin-L obtained by long-period extraction had no characteristic differences from control.
The total amounts of free amino acids in the muscle of rats fed on protein-free diet showed an inclination of slight decrease, as compared with those of control rats.
