net protein utilization


Also found in: Acronyms, Encyclopedia, Wikipedia.

net protein utilization (NPU)

a measure of protein quality based on the percentage of ingested nitrogen that is retained by the body. Because NPU does not take into account differences in the digestibility of proteins, it gives a poorly digested but good-quality protein a false low value.

net pro·tein u·ti·li·za·tion

(NPU) (net prō'tēn yū'ti-lī-zā'shŭn)
Measurement of the body's use of ingested protein.

net protein utilization (NPU),

n a comparison between the amount of nitrogen taken into the body and the amount retained, which results in a percentage value; includes a determination of whether the protein containing the nitrogen is capable of being digested in the first place.
