Protein and Amino Acid Requirements of Mammals focuses on the determination of the protein and amino acid requirements of various mammals, including man in particular. The selection first offers information on some species and age differences in amino acid requirements and the methods of measuring the nutritive value of protein hydrolysates and amino acid mixtures. Discussions focus on assay methods based on protein regeneration; specificity of amino acid requirements; amino acid requirements for nitrogen equilibrium in the adult; and composition of tissue proteins and amino acid requirements for growth. The text then examines the laboratory evaluation of amino acid mixtures and protein hydrolysates and dietary proteins and synthesis of tissue proteins. Topics include role of dietary proteins in the hypertrophy of gonads, effect of dietary proteins on repletion of liver proteins, and effect of dietary proteins on the synthesis of plasma proteins. The publication examines the protein and amino acid requirements of man, including qualitative amino acid requirements of various species, growth and protein and amino acid needs, and metabolic interactions of essential and nonessential amino acids. The selection is a dependable reference for researchers interested in the determination of the protein and amino acid requirements of mammals, including man.
