HGH (Human Growth Hormone)

1. HGH (Human Growth Hormone)

Human growth hormone (HGH) (GH), also known as somatotropin or as human growth hormone (HGH) in its human form, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important in human development. It is a type of mitogen which is specific only to certain kinds of cells. Human Growth hormone (HGH) is a 191-amino acid, single-chain polypeptide that is synthesized, stored, and secreted by somatotropic cells within the lateral wings of the anterior pituitary gland. Growth hormone fuels childhood growth and helps maintain tissues and organs throughout life. It's produced by the pea-sized pituitary gland located at the base of the brain. Beginning in middle age, however, the pituitary gland slowly reduces the amount of growth hormone it produces .GH is a stress hormone that raises the concentration of glucose and free fatty acids.It also stimulates production of IGF-1. A recombinant form of HGH (Human Growth hormone) called somatropin (INN) is used as a prescription drug to treat children's growth disorders and adult (HGH) growth hormone deficiency. Reference

The names somatotropin (STH) or somatotropic hormone refer to the human growth hormone (HGH) produced naturally in animals and extracted from carcasses. Hormone extracted from human cadavers is abbreviated hGH. The main growth hormone produced by recombinant DNA technology has the approved generic name somatropin (INN) and the brand name Humatrope, and is properly abbreviated rhGH in the scientific literature. Human growth hormone (HGH) secretion is stimulated by growth hormone-releasing hormone (GHRH) and is inhibited by somatostatin. In addition, GH secretion is pulsatile, with surges in secretion occurring after the onset of deep sleep that are especially prominent at the time of puberty. In normal subjects, human growth hormone (HGH) secretion increases in response to decreased food intake and to physiological stresses and decreases in response to food ingestion. However, some individuals are affected by abnormalities in human growth hormone (HGH) secretion, which involve either deficiency or overabundance of the hormone. Your body still needs growth hormone after you’ve finished puberty. Reference

Human growth hormones (HGH) play an important role in normal human growth and development. The major human growth hormone is a protein made up of 191 amino acids, the building blocks of proteins. The production of this protein is controlled by two other hormones secreted by the hypothalamus: growth hormone releasing hormone (GHRH), which controls secretion of human growth hormone (HGH); and growth hormone-inhibiting hormone (GHIH), which inhibits secretion of human growth hormone (HGH). All healthy individuals have measurable levels of hGH throughout life, but there are two notable growth spurts, one at birth and the other at puberty, and hGH plays a vital role at each time. The most obvious effect of human growth hormone (HGH) is on linear skeletal growth (height), but metabolic effects of hGH (the results of hGH activity in the body) on muscle, the liver, and fat cells are a critical part of its function. When any question arises about growth or development, pediatricians may investigate the levels of the major human growth hormone (HGH), its receptors and stimulants, the glands that produce the hormones, and the complex hormone interactions that control normal development. mino acids are biologically important organic compounds.
