Hormones and hormones, which play an important role in regulating the metabolism, growth, development and reproduction of the body, are chemical information substances synthesized by highly differentiated endocrine cells and secreted directly into the blood. It influences the physiological activities of the body by regulating the metabolic activities of various tissues and cells. It is an important substance in our life, and nowadays, any chemical substance whose information is transmitted through blood circulation or tissue fluid is called hormone. Hormones have a wide range of actions, but they do not participate in specific metabolic processes, but only regulate specific metabolic and physiological processes. They regulate the speed and direction of metabolic and physiological processes, thus making the body’s activities more responsive to changes in the internal and external environment. The mechanism of action of hormones is to transmit information into the cell by binding to specific receptor proteins on the cell membrane and in the cytoplasm, causing a series of corresponding chain changes in the cell, and finally expressing the physiological effects of the hormone.
