Patricia Reynolds · Answer 1

Essential amino acids are called essential because these proteins are not synthesized by the human body, while non essential amino acids are readily manufactured in our body. That is why it is important to consume foods rich in protein to have complete types of protein in our body.

The correct answers are:

Essential amino acids:

Made from Aspartate and Pyruvate in an eleven-step pathway

Branched-chain amino acids

Obtained from food only

Methionine

Threonine

Nonessential amino acids:

Synthesized by humans

An amino acid synthesized from pyruvate in humans

Both

The amino acid that is a thioether

Derived from 3-phosphoglycerate, a glycolytic intermediate
