Growth hormone, also called growth hormone, is a protein hormone secreted by the pituitary gland. It plays an important regulatory role in the growth and development of humans and other vertebrates.
1. Structure: Growth hormone is a polypeptide molecule composed of proteins. It is composed of 191 amino acid residues and has two sulfur-oxygen hormone Bridges. This structure gives it specific biological activity.
2. Secretion: Growth hormone is secreted by growth hormone cells in the anterior pituitary. Its secretion is regulated by a variety of factors, including stimulation of the nervous system, hormone levels in the body, and the influence of diet and sleep.
Impact on growth: It mainly promotes the growth of epiphysis, and it also directly acts on the body's tissue cells to hypertrophy, which is achieved by insulin-like growth factor.
2. Promote protein synthesis.
3. Fat metabolism: Mobilizing stored fat, Chemicalbook increased free fatty acids in blood and increased blood ketone bodies.
4. Glucose metabolism: It has an anti-insulin effect and also reduces the number and affinity of insulin receptors.
5. Water and salt metabolism: the excretion of sodium, potassium, magnesium, chlorine and inorganic phosphorus in urine is reduced, and the metabolism of calcium and phosphorus is positively balanced.
