Correct option is B
Glycine and
Proline are
non-essential amino acids. Non-essential amino acids are those that the body can synthesize on its own, so they do not need to be obtained through diet. Both glycine and proline are involved in various physiological processes, such as collagen formation (proline) and being the simplest amino acid (glycine).
Information Booster:
·
Glycine is the simplest amino acid and is involved in the synthesis of proteins, peptides, and other important molecules. It is crucial in the formation of collagen and also functions as an inhibitory neurotransmitter.
·
Proline plays a key role in the structure of collagen, a major protein in connective tissues. It is involved in wound healing and supports the integrity of the skin, joints, and blood vessels.
Additional Knowledge:
·
Leucine, Isoleucine: These are
essential amino acids, meaning they must be obtained from the diet.
·
Valine, Methionine: These are also
essential amino acids.
·
Lysine, Tyrosine:
Lysine is an essential amino acid, while
Tyrosine is non-essential, as the body can synthesize it from phenylalanine. However, the pair in this option includes one essential and one non-essential amino acid.
