:somatostatine 28
Description :
somatostatine 28 est une hormone peptidique qui joue un rôle crucial dans la régulation de divers processus physiologiques, y compris l'inhibition de la libération de l'hormone de croissance et la modulation de la sécrétion d'insuline et de glucagon. C'est un membre de la famille de la somatostatine, qui se compose de plusieurs isoformes, somatostatine 28 étant l'une des formes les plus longues, dérivée du précurseur préprosomatostatine. Ce peptide est composé de 28 acides aminés et présente une structure cyclique qui contribue à sa stabilité et à son activité biologique. somatostatine 28 est principalement produit dans l'hypothalamus et le tractus gastro-intestinal, où il agit sur des récepteurs spécifiques pour exercer ses effets. Ses fonctions s'étendent au système nerveux central, où il influence la neurotransmission et la signalisation neuroendocrine. Le numéro CAS 73032-94-7 identifie de manière unique ce composé dans les bases de données chimiques, facilitant la recherche et l'application en pharmacologie et en biochimie. Dans l'ensemble, somatostatine 28 est significatif tant dans les contextes cliniques que de recherche, en particulier dans la compréhension de la régulation hormonale et des applications thérapeutiques potentielles dans les troubles endocriniens.

Somatostatin-28
CAS :The octacosapeptide somatostatin-28 arises from the posttranslational cleavage of prosomatostatin, which in turn is derived from a larger precursor, preprosomatostatin. S-28 was first isolated from porcine duodenum. In guinea-pig pancreatic acini, S-28, unlike S-14, increased amylase secretion, cellular cyclic GMP, and Ca²⁺ outfluxes.Formule :C137H207N41O39S3Degré de pureté :> 95%Couleur et forme :Whitish PowderMasse moléculaire :3148.6Somatostatin-28
CAS :<p>Somatostatin-28 H-Ser-Ala-Asn-Ser-Asn-Pro-Ala-Met-Ala-Pro-Arg-Glu-Arg-Lys-Ala-Gly (Disulfide bond) is a peptide hormone that is produced in the body by different tissues, including the pancreas. Somatostatin inhibits the release of various hormones, including growth hormone and insulin. It also has been shown to inhibit cell proliferation, tumor growth and angiogenesis in vitro. Somatostatin is used to diagnose diseases such as acute pancreatitis, chronic pancreatitis and prostate cancer. The somatostatin analog octreotide has been shown to reduce symptoms of diarrhea in patients with AIDS.</p>Formule :C137H207N41O39S3Degré de pureté :Min. 95%Masse moléculaire :3,148.56 g/molSomatostatin-28
CAS :Somatostatin-28 is the 28 amino acid isoform of somatostatin and has similar activity to the 14 amino acid isoform. While the 14 amino acid form mainly acts in the brain, somatostatin-28 mainly operates in the gastrointestinal tract. Somatostatin is a peptide hormone that is widely expressed throughout the body for example in the gastrointestinal (GI) tract, hypothalamus, pancreas and the central nervous system. It has been found to inhibit pituitary growth hormone release as well as endocrine, pancreatic and GI secretions. In the central nervous system somatostatin plays a role in neurotransmission modification and it has also demonstrated to be effective against a number of cancers such as squamous carcinoma.Formule :C137H207N41O39S3Degré de pureté :Min. 95%Masse moléculaire :3,148.62 g/molSomatostatin 28
