Peptides
Les peptides sont des chaînes courtes d'acides aminés liées par des liaisons peptidiques, jouant un rôle essentiel en tant que molécules biologiques dans divers processus cellulaires. Ils fonctionnent comme hormones, neurotransmetteurs et molécules de signalisation, et sont largement utilisés dans les applications thérapeutiques et diagnostiques. Les peptides sont également cruciaux dans la recherche pour étudier les interactions protéiques, les activités enzymatiques et les voies de signalisation cellulaire. Chez CymitQuimica, nous proposons une large sélection de peptides de haute qualité pour soutenir vos besoins en recherche et développement en biotechnologie et en pharmacie.

Ghrelin (Human, 1-14)
Amino acids 1-14 of Ghrelin, a peptide hormone that is found in the stomach, brain and other tissues. Ghrelin associates with growth hormone secretagogue receptors (GHS-R) through its unique N-octanoyl group which is linked to its serine 3 residue covalently. As a result it is able to influence the body in various ways such as stimulating appetite, nutrient sensing, meal initiation and the regulation of insulin resistance, diabetes and obesity. Its wider functions are also associated with glucose homeostasis, energy homeostasis, cardio-protective effects, bone metabolism and its potential to be a target for cancer means that it can be used to develop therapies for a whole spectrum of diseases. This molecule is used as a research tool for studying cell biology and pharmacology.Formule :C76H121N22O24Degré de pureté :Min. 95%Masse moléculaire :1,725.94 g/molHepcidin-24 (Human)
Consisting of the disulfide Bonds: Cys6- Cys22, Cys9-Cys12, Cys10- Cys18, and Cys13-Cys21 and of the trifluoroacetate salt form, this product can be used as an internal standard for Hepcidin assays.Hepcidin-24 is a peptide hormone that plays a key role in the regulation of iron metabolism in the body. It is produced by the liver and is secreted into the bloodstream, where it interacts with cells in the intestine and other tissues to control the absorption and distribution of iron. Hepcidin acts as a negative regulator of iron uptake and release by binding to and inhibiting the activity of ferroportin, a protein that facilitates the export of iron from cells into the bloodstream. When hepcidin levels are high, ferroportin activity is reduced, leading to decreased iron absorption from the diet and reduced iron release from cells. When hepcidin-24 levels are low, ferroportin activity is increased, leading to increased iron absorption and release. Imbalances in hepcidin levels can lead to a variety of disorders, including iron-deficiency anemia, hemochromatosis (an iron overload disorder), and anemia of chronic disease. Therefore, hepcidin-24 is a key target for the development of treatments for these and other iron-related disorders. In addition to its role in iron metabolism, hepcidin has been shown to have antimicrobial properties, as it can inhibit the growth of certain bacteria and fungi. It may also be involved in the regulation of immune function and inflammation.Formule :C109H165N33O28S9Degré de pureté :Min. 95%Masse moléculaire :2,674.31 g/molalpha-Mating Factor acetate salt

CAS :Amyloid beta peptide (Aβ) is a neurotrophic factor that is involved in the pathogenic mechanism of Alzheimer's disease. This drug inhibits the production of Aβ by binding to the enzyme, secretase. It has been shown that Aβ binds to a transporter protein and is transported into cells, where it accumulates in the cytoplasm. The physiological levels of Aβ are regulated by proteins called "gene chaperones" which prevent Aβ from aggregating into plaques. Dextran sulfate inhibits this process by binding to amyloid and preventing it from accumulating in the cytoplasm. Amyloid beta peptide trifluoroxalate (ATFX) has been shown to inhibit the production of Aβ with structural analysis, inhibition of cellular uptake and secretion, and inhibition of fibrillization. ATFX also has potential as a biomarker for Alzheimer's disease because it can be detected at low concentrations in urine or serumFormule :C194H295N53O58S·C2HF3O2Degré de pureté :Min. 95%Couleur et forme :White PowderMasse moléculaire :4,443.83 g/molH-Glu(Met-OH)-OH
CAS :H-Glu(Met-OH)-OH is an enzyme that catalyzes the conversion of stachyose to sucrose. It is also a synthetase that catalyzes the formation of fatty acids. H-Glu(Met-OH)-OH has been shown to be active in cancer cells and may be used as a potential therapeutic target for cancer treatment. This enzyme is inhibited by sodium hydroxide solution, hydrochloric acid, and urea nitrogen. The activity of H-Glu(Met-OH)-OH is measured by its ability to synthesize fatty acids from glucose in the presence of ATP and NADPH. Hydroxide solution can also be used to measure the activity of H-Glu(Met-OH)-OH as it converts stachyose to sucrose in the presence of ATP, NADP+, and sodium hydroxide solution. The rate at which this reaction occurs can be measured using a spectrophotometer with a carboxylate absorbFormule :C10H18N2O5SDegré de pureté :Min. 95%Couleur et forme :SolidMasse moléculaire :278.33 g/molLeuprolide Human
