a short section of a protein peptide bonds alanine H2N CH C CH2OH OH O serine H2N CH C H OH O glycine several individual amino acids
Chapter 27: Amino Acids, Peptides, and Proteins monomer unit: α-amino acids Biopolymer: the monomeric amino acids are linked through an amide bond (the
amino acids bound by amide (peptide) bond classification of basic amino acids according the structure of side-chain and functional groups
A Peptide Bond 1 join amino group of one amino acid with carboxyl group of another by forming and amide bond between them → Peptide Bond
4 4 5 Polar/basic amino acids: Lysine, Arginine and Histidine of amino acids with TiO2 surfaces elucidating the peptide bond for-
PEPTIDES Peptides- Amino acids are joined covalently to form peptide bonds Polymerization results in the linkage between two AA which takes place due to
Further condensation reactions result in a polypeptide The amino acid units are linked by peptide bonds (sometimes called peptide links) R1-COOH + R2-NH2
linked together by amide bonds Scheme 1 shows representation for an α-amino acid and peptide The repeating units in peptide is called amino acid residue
explain why peptide bonds are polar and prefer the trans configuration • explain how side chains confer distinct chemical and physical properties on amino
