Growth Regulator (other)
Growth regulator may refer to: * Growth hormone, stimulates growth in humans and other animals * Insect growth regulator, used as insecticides * Plant hormone Plant hormones (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, including embryogenesis, the regulation of Organ (anat ...

Growth Hormone
Growth hormone (GH) or somatotropin, also known as human growth hormone (hGH or 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. GH also stimulates production of insulin-like growth factor 1 (IGF-1) and increases the concentration of glucose and free fatty acids. It is a type of mitogen which is specific only to the receptors on certain types of cells. GH 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. A recombinant form of HGH called somatropin ( INN) is used as a prescription drug to treat children's growth disorders and adult growth hormone deficiency. In the United States, it is only available legally from pharmacies by prescription from a licensed health care provider. In recent years in the United States, some health ...

Insect Growth Regulator
An insect growth regulator (IGR) is a chemical insecticide that kills insects indirectly by disrupting their life cycles. The term was initially proposed to describe the effects of juvenile hormone analogs. Although the term "insect growth disruptor" more accurately describes the actions of IGRs, it did not become widely used. IGRs encompass chemical classes with three modes of action ( mechanisms of action): juvenile hormone analogs, chitin synthesis inhibitors, and ecdysone receptor agonists. Juvenile Hormone analogs Juvenile hormone analogs are also known as juvenile hormone mimics, juvenoids, or JH signaling activators. Juvenile hormone (JH) controls many important processes in insects including metamorphosis. After the structure determination of the JHs in the 1960s, the search for more stable and useable analogs started. Zoecon introduced methoprene in 1975, and later hydroprene and kinoprene. Later again other companies introduced the more stable fenoxycarb and pyripro ...
