Define protein quality.

Question

Quizplus · Accepted Answer

Protein quality refers to how efficiently a protein in the diet can be used to make body proteins. It is determined by the amount and balance of essential amino acids in the protein. A high-quality protein contains all the essential amino acids in sufficient amounts to support growth and maintenance of body tissues. The measurement of nonessential amino acids in a food compared to a reference protein (choice A) is used to determine the protein digestibility corrected amino acid score (PDCAAS), which is one way to assess protein quality. The freshness of meat (choice B) is not related to protein quality, and the ratio of nonessential to essential amino acids (choice D) is not a relevant measure of protein quality.
