Biological value of protein is related to
Correct Answer: Protein quality
Description: The indices are used to assess the nutritional value of proteins. Biological Value (BV) of Protein : It is the ratio between the amount of nitrogen retained and nitrogen absorbed during a specific interval. Net Protein Utilization (NPU): NPU = Retained nitrogen / intake of nitrogen x 100 Net Dietary Protein Value (NDPV): This will assess both quantity and quality of the proteins in the diet. NDPV = Intake of N x 6.25 x NPU Protein Efficiency Ratio (PER) It is the weight gain per gram of protein taken. The essential amino acid content can also be expressed in terms of chemical score (mg of amino acid per gram of protein).
