Question

Which of the following determines the protein quality of food?

• A. Amino acids mixture
• B. Fibre content
• C. Protein amalgamation
• D. Vegetable or animal origin

Answer 1

The correct option is A Amino acids mixture

Protein quality describes characteristics of a protein in relation to its ability to achieve defined metabolic actions. Traditionally, this has been discussed solely in the context of a protein's ability to provide specific patterns of amino acids to satisfy the demands for synthesis of protein as measured by animal growth or, in humans, nitrogen balance. As understanding of protein's actions expands beyond its role in maintaining body protein mass, the concept of protein quality must expand to incorporate these newly emerging actions of protein into the protein quality concept. New research reveals increasingly complex roles for protein and amino acids in regulation of body composition and bone health, gastrointestinal function and bacterial flora, glucose homeostasis, cell signaling, and satiety.

So the correct option is 'amino acids mixture'.
