Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. 73724-45-5, formula is C18H17NO5, Name is Fmoc-Ser-OH. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3. Recommanded Product: Fmoc-Ser-OH.
Paprocki, Maciej P.;Rasmussen, Jakob E.;Soerensen, Kasper K.;Jensen, Knud J. research published 《 Safety-catch linkers for Fmoc solid-phase synthesis of peptide thioesters and hydrazides by amide-to-imide activation》, the research content is summarized as follows. The use of C-terminal peptide thioesters and hydrazides in synthetic protein chem. has inspired the search for optimal solid-phase peptide synthesis (SPPS) strategies for their assembly. However, peptide thioesters are not directly accessible by conventional Fmoc-SPPS (Fmoc = 9-fluorenylmethoxycarbonyl) owing to the nucleophilicity of the secondary amine required for Fmoc removal. Here, we report the mild and effective activation of the pGlu linker and a new safety-catch linker that was used for the convenient synthesis of peptide thioesters and hydrazides via efficient amide-to-imide activation followed by nucleophilic displacement.
73724-45-5, Fmoc-Ser-OH, also known as Fmoc-Ser-OH, is a useful research compound. Its molecular formula is C18H17NO5 and its molecular weight is 327.3 g/mol. The purity is usually 95%.
Fmoc-L-Ser-OH is a synthetic peptide that belongs to the group of glycopeptides. It is used as a model for such compounds and has been shown to have antimicrobial activity in vitro against gram-positive bacteria, especially Staphylococcus epidermidis. This compound was synthesized from 3-mercaptopropionic acid and chloride in the presence of hydroxyl groups and epidermal growth factor. The synthetic pathway can be divided into three steps: (1) condensation of 3-mercaptopropionic acid with hydrochloric acid to yield 3-mercaptoacrylic acid; (2) esterification of 3-mercaptoacrylic acid with glycine to form Fmoc-L-Ser; and (3) deprotection of Fmoc protecting group., Recommanded Product: Fmoc-Ser-OH
