Fórmula:C51H85N11O12SPeso molecular:1,076.35 g/molDes-n-Octanoyl-[Ser3]-Ghrelin (Human, 1-14)
Des-n-Octanoyl-[Ser3]-Ghrelin (Human, 1-14) is a non-Acylated Analog of Ghrelin (Human, 1-14), amino acids 1-14 of the peptide hormone Ghrelin. This peptide does not contain the unique N-octanoyl group which is linked to Ghrelin's third serine residue covalently and which allows Ghrelin to associate with the growth hormone secretagogue receptor (GHS-R). Through interaction with the GHS-R, Ghrelin can exert its various effects on the body 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.Fórmula:C68H106N22O23Pureza:Min. 95%Peso molecular:1,599.74 g/molIGF-I (1-3)
Custom research peptide; min purity 95%.Fórmula:C12H19N3O6Pureza:Min. 95%Peso molecular:301.3 g/molHumanin (human)
CAS:Encoded for by mitochondrial DNA, Humanin is an endogenous peptide known to be a ‘rescue factor’ with the ability to abolish neuronal cell death. This characteristic has promoted Humanin as a potential treatment for Alzheimer’s disease. Another function of Humanin is it can inhibit mitochondira-dependent apoptosis through preventing the formation of apoptotic bodies and the release of Cytochrome C.Humanin has been found to be related to aging related cardiovascular disease (ACVDs) due to evidence of Humanin serum levels as age increases. Furthermore Humanin increases the expression of antioxidant defense system proteins and impedes complexes I and III from their activity in the electron transport chain in myocardial cells and mitochondria, therefore decreasing oxidative stress damage caused by H2O2. Humanin further reduces reactive oxygen species production and protects cardiomyocytes and fibroblasts, from oxidative stress.Overall Humanin has a variety of protective functions such as mitochondrial homeostasis and redox systems regulation, anti-aging, prevention of myocardial fibrosis, anti-inflammation, metabolism improvement and autophagy promotion. It has also been found to improve beta-cell survival and thus can be used as a diabetes treatment due to it improving insulin secretion and resistance.Fórmula:C119H204N34O32S2Pureza:Min. 95%Forma y color:PowderPeso molecular:2,687.28 g/mol(Gly106)-Cytochrome C (92-107) (Manduca sexta)
