Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. 73724-45-5, formula is C18H17NO5, Name is Fmoc-Ser-OH. Ethers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. Product Details of C18H17NO5.
Wang, Zhuoer;Hao, Aiyou;Xing, Pengyao research published 《 Helical secondary structures and supramolecular tilted chirality in N-terminal aryl amino acids with diversified optical activities》, the research content is summarized as follows. Helix structures at at./mol. level have not been found in self-assembled peptide sequence with less than three residues. As β-sheet supramol. secondary structures have been discovered in solid-state amino acids, we here report the conjugation of simple N-terminal aryl protecting group could give rise to helical supramol. secondary structures in solid-state, which determines the optical activities of the adjacent aryl groups. The carboxylic acid-involved asym. H-bonds in N-terminal aryl amino acids induce the emergence of super-helical structures of amino acid residues and aryl groups. In most cases, supramol. tilted chirality of aryl groups is opposite to that of amino acid sequences, of which handedness and helical pitch are determined by the H-bond modalities. Determining correlation between supramol. tilted chirality of aryl segments and their chiroptical activities is firstly unveiled, which was verified by the computational results based on d. functional theory. Most aryl amino acids self-assembled by nanopptn. method via crystallization induced self-assembly into rigid one-dimensional microstructures with ultra-high Young’s modulus. This study reveals the generic existence of chiral supramol. structures in aggregated amino acid derivatives and gives an in-depth investigation into the structural-property relationships, which could guide the rational design and screening of chiroptical supramol. materials.
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., Product Details of C18H17NO5
