Proteins make amino acids. Insulin is an amino acid that:
A
Transport oxygen
B
Regulate the level of sugar in the blood
C
Fight diseases
D
Speed up the rate of chemical reaction
Explanation: 

Detailed explanation-1: -Glycine, serine, glutamine, and asparagine were associated with improved insulin sensitivity, whereas all other AAs were associated with decreased insulin sensitivity. Glutamate, tyrosine, isoleucine, and alanine had the largest effect on the reduction of insulin sensitivity.

Detailed explanation-2: -Protein Cell. 2010 Jun; 1(6):537-51. doi: 10.1007/s13238-010-0069-z.

Detailed explanation-3: -Four amino acids were found to be particularly important for stimulating -cell electrical activity, essential for insulin secretion (leucine, isoleucine, alanine, and arginine).

Detailed explanation-4: -Thioredoxin-interacting protein regulates insulin transcription through microRNA-204.
