Net protein utilization
The net protein utilization, or NPU, is the ratio of amino acid mass converted to proteins to the mass of amino acids supplied. This figure is somewhat affected by the salvage of essential amino acids within the body, but is profoundly affected by the level of limiting amino acids within a foodstuff. It is used as a measure of "protein quality" for human nutritional purposes. Certain foodstuffs, such as eggs or milk, rate as 1 on an NPU chart. Experimentally, this value can be determined by determining dietary protein intake and then measuring nitrogen excretion. One formula for NPU is:
