Nutritional Equivalence of -Lactoglobulin and Its Corresponding Amino Acids

Abstract

In mouse growth studies crystalline [beta]-lactoglobulin was compared with a mixture of L amino acids duplicating its composition and with casein and lactalbumin. The pure protein and its amino acid counterpart gave equal growth and efficiency of dietary N utilization. Casein and lactalbumin provided superior growth rates to both the B. lactoglobulin and its amino acid counterpart.
