CC   -!- FUNCTION: Insulin decreases blood glucose concentration. It increases
CC       cell permeability to monosaccharides, amino acids and fatty acids. It
CC       accelerates glycolysis, the pentose phosphate cycle, and glycogen
CC       synthesis in liver.
CC   -!- SUBUNIT: Heterodimer of a B chain and an A chain linked by two
CC       disulfide bonds.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- SIMILARITY: Belongs to the insulin family. {ECO:0000305}.
