Concept explainers
(a)
Interpretation: To classify proline as an essential amino acid or a nonessential amino acid.
Concept introduction: Amino acids are the main building blocks of proteins. Amino acids are classified as essential and non-essential depending upon whether they can be synthesized within the body itself or not.
Essential amino acids are those amino acids which cannot be synthesized by the body via biosynthesis and thus must be taken from the outside in form of dietary protein to meet the body’s need. Those amino acids which can be synthesized by biosynthesis within the liver are termed as non-essential amino acids.
The essential amino acids are arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
The non-essential amino acids are alanine, asparagines, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine.
(b)
Interpretation: To classify glycine as an essential amino acid or a nonessential amino acid.
