Enzyme Function | FUNCTION: CHH is the most abundant hormone in the sinus gland of isopods and decapods which controls the blood sugar level. Has a secretagogue action over the amylase released from the midgut gland. May act as a stress hormone.; FUNCTION: MIH may inhibit Y-organs where molting hormone (ecdysteroid) is secreted and a molting cycle is initiated when MIH secretion diminishes or stops. |
