Question

When dietary amino acids are low, the body begins breaking down proteins from what source?

Answer 1

When dietary amino acids are low, the body begins breaking down proteins from the SKELETAL MUSCLE. Amino acids are the building blocks of proteins.

Protein is a fundamental macronutrient that must be included in the diet at an appropriate amount.

A sedentary adult needs to consume daily almost 0.8 grams (gr) of protein per kilogram (kg) of body weight.

In the body, the skeletal muscle tissue is a primary reservoir site of amino acids, which are stored as proteins.
