What is the difference between a dietary essential amino acid and a dietary nonessential amino acid?

Question

What will be an ideal response?

Answer 1

THIS IS ANOTHER KEY LEARNING POINT—THEY NEED TO

UNDERSTAND THAT ALL AMINO ACIDS ARE REQUIRED, THE BODY CAN

MAKE SOME AND NOT OTHERS. IF THE BODY CAN MAKE SOME, WHICH

ARE REALLY MORE IMPORTANT TO SURVIVAL—THE ONES THEY CAN

MAKE OR THE ONES THEY CANNOT? HINT: WHAT HAPPENS WHEN WE

TAKE SOME ESSENTIAL AMINO ACIDS OUT OF THE DIET—DO THE

ANIMALS SURVIVE (YES). BUT THEY DON'T THRIVE.

A critically important concept in nutrition is that of dietary essential amino acids (Figure 4.1, 50). An essential amino acid is one that the animal cannot make or cannot make enough of to live well or even survive for long periods. Therefore, essential amino acids must be consumed in the diet. If an animal can make enough of the amino acid in its own body, it is nonessential in the diet, which means the animal can make it from other amino

acids and glucose. Nonessential amino acids for most species include glycine, alanine, cystine, cysteine, serine, glutamate, aspartate, tyrosine, glutamine, asparagine, proline, ornithine and citrulline. There are species differences; for examples, birds need more glycine
