Which one of the following hormones is not involved in sugar metabolism?

B.
Aldosterone
Aldosterone is not involved in sugar metabolism. It is a steroid hormone (mineralocorticoid) produced by the outer section(zona glomerulosa) of the adrenal cortex in the adrenal gland. It plays a central role in the adrenal gland. It plays a central role in the regulation of blood pressure mainly by acting on the distal tubules and collecting ducts of the nephron, increasing reabsorption of ions and water in the kidney, to cause the conservation of sodium, secretion of potassium, increase in water retention and decrease in blood pressure and blood volume.
