Which of the following is an amino acid?
A
leucine
B
glucose
C
monosaccharide
D
fructose
Explanation: 

Detailed explanation-1: -Leucine is an -amino acid, meaning it contains an -amino group (which is in the protonated −NH3+ form under biological conditions), an -carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a side chain isobutyl group, making it a non-polar aliphatic amino acid.

Detailed explanation-2: -Fortunately, plenty of healthy, tasty foods contain leucine, including eggs, seeds, oats, legumes, and spirulina, and they’re all easy to incorporate into your diet.

Detailed explanation-3: -Leucine (Leu) is a nutritionally essential branched-chain amino acid (BCAA) in animal nutrition. It is usually one of the most abundant amino acids in high-quality protein foods.

Detailed explanation-4: -The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Detailed explanation-5: -The essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. The nonessential amino acids are alanine, asparagine, aspartic acid, glutamic acid, and serine.
