Determine whether each of the examples or phrases describes an essential amino acid, a nonessential amino acid, or both essential and nonessential amino acids. a table of amino acids can be found here. note: if you answer any part of this question incorrectly, a single red x will appear indicating that one or more of the phrases are sorted incorrectly.

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
