Abstract

THE glycine and α-amino nitrogen concentrations in rabbit foetal muscle are approximately three times as great as in maternal muscle1. Previous studies on regenerating rat liver indicate increased concentrations of α-amino nitrogen and glutathione during regeneration2. These observations suggest a relationship between high concentrations of amino acids and increased protein synthesis. Studies of the amino acid concentrations of tumours also show that elevated concentrations of amino acids are present during rapid growth3. The foetal liver of the guinea-pig, however, unlike foetal muscle, has been found to have the same concentration of amino acids as the maternal liver.
