A comparative study is presented on the solid-phase peptide synthesis (SPPS) of the acyl carrier protein (ACP 65–74) sequence on a series of Rink amide resins possessing different matrix structures: poly(vinyl alcohol)- graft -poly(ethylene glycol) (PVA- g -PEG, 4 ), Tentagel-S-RAM (...
Comparison of muonium and positronium with hydrogen atoms in their reactions towards solutes containing amide and peptide linkages in water and micelle solutions中国信息技术软件产业国际化Rate constants have been sought for the reaction of muonium (Mu) and o-positronium (Ps) with solutions of ...
Amide bond formation on the resin (peptide coupling) All amide couplings were performed manually on the synthesis column. A solution with 10 equivalents of acid monomer, 10 equivalents of PyBOP and 30 equivalents ofN-methylmorpholine was first prepared in 400 μL of DMF. This was then taken ...
The effect of the insulinotropic gut hormone glucagon-like-peptide-1 (GLP-1) was studied on the residual insulin capacity of prediabetic nonobese diabetic (NOD) mice, a model of insulin-dependent diabetes mellitus (type 1). This was done using isolated pancreas perfusion and dynamic islet peri...

By repeating this process for all on-exchange time points the mass increase of each proteolytic peptide over the time course of deuterium exposure can be determined. From these data the rates of deuterium exchange can be determined for the corresponding areas of the intact protein. Since the ...
Mechanism-based kinetic models were used to generate rate constants from the concentration vs. time profiles.Deamidation of Gly-Phe-L-Asn-Gly in lyophiles resulted in L- and D-aspartyl and isoaspartyl-containing peptides and four amide-linked adducts between the succinimide and Gly-Val. The ...
