High Quality Human Growth Hormone Fast Delivery and Hassle-Free Returns for sale good price

Human growth hormone (GH) is a single-chain, non-glycosylated, hydrophilic globulin composed of 191 amino acids, with a molecular weight of 21,700 Da and an isoelectric point pI of 4.9. The cysteine ​​residues at positions 53 and 165 and between 182 and 189 are connected by disulfide bonds; about 75% of the growth hormone secreted by eosinophils in the anterior lobe of the pituitary gland is secreted in the form of this molecular structure. 5% to 10% are secreted in the form of a molecular weight of 20kDa.

Spontaneous secretion of Human Growth Hormone takes the form of paroxysms during the day and night, generally occurring in the first slow-wave sleep period (SWS) after physiological sleep. Resting during the day seems to promote the release of Human Growth Hormone. Food intake, fasting, exercise and stress can affect the secretion form of Human Growth Hormone, but do not change its basic rhythm. In adolescence, Human Growth Hormone secretion amplitude is high, the frequency is fast, and the total amount of day and night secretion is large, while in the elderly The opposite is true.

Human Growth Hormone

The synthesis and release of GH are stimulated by growth hormone-releasing hormone a nd ghrelin, and are inhibited by somatostatin. Gonadotropin-releasing hormone, thyroid ho rmone, corti**l, insulin-like growth factor (IGF)-I, and activin are also involved in the regul ation of GH synthesis and release.

Purified and recombinant human GH are agonists. Antibodies to GHR and pegvisomant (GHR antagonist) are antagonists.

The GH receptor (GHR) belongs to the type I cytokine receptor family.6 Human GHR (So matotropin) consists of 638 aa residues that contain single extracellular, transmembrane, and intracellular domains. The extracellular domain of GHR has conserved cysteine resid ues and two antiparallel B-sheets holding the GH binding site in between while the intracel lular domain has two conserved Pro-rich sequences, Box 1 and Box 2. The initial step in GH signaling is the dimerization of two GHRs,6 which leads to the activation of JAK2 by ty rosine phosp**rylation. The activated JAK2 then interacts with and directly activates other signaling molecules such as STAT, SHC, FAK, and PLC. GH also activates the MAPK pat hway.
