There has been a great deal of investigations on relationship between structure and properties in the solid state of various polymers. Among these the synthetic poly(amino acid) has been attracting a growing attention because of their unique rigid conformation of the backbone chain. It has been ...

Basic Amino Acid Structure: alpha carbon, hydrogen atom, carboxyl group, amino group, "R" group (side chain).Yassine Mrabet/Wikimedia Commons Generally,amino acidshave the following structural properties: A carbon (the alpha carbon) A hydrogen atom (H) A Carboxyl group (-COOH) An Amino group...
A series of novel 2-[5-(aryloxyacetyl)-amino-1,3,4-thiadiazol-2-ylthio] propionate derivatives were synthesized in high yield, and their structures were characterized by IR, 1H NMR, 13C NMR, and elemental analysis, coupled with one selected single-crystal X-ray structure determination. The...
Amino acid based surfactants, which have an amino acid residue as a hydrophilic moiety, are reviewed with respect to their properties and applications. Salts of N α-acyl amino acids have an amino acid side chain radical in the hydrophilic moiety, an amide linkage and a chiral carbon atom, ...
The Amino Acid Structure Chart and Reference Table Chart describes the biological properties and solubility of the 20 standard amino acids.
20、p adjacent to the peptide bond cannot rotate freely, this rigidity of the peptide bond holdsthe six atoms in a single plane. the amino (_NH_) group does not ionize between ph o and 14 due to the double-bond properties of the peptide bond. In addition, r groups on amino acid res...
Most amino acids have the basic formula RCHNH2COOH and have properties of both bases and acids, because each amino acid has an amino group (NH2) and a carboxyl group (COOH). In the simplest amino acid, glycine, R is represented by a hydrogen atom (CH2NH2COOH). In others, R may be ...
Amino acid structure Chemical structure of an amino acid. Marked the carboxyl group (yellow), amino group (blue) and the chain or radical (green). All amino acids have an amino group and an acid group. They differ from each other by the structure of its chain. Sometimes the chain contain...
