Structural Biochemistry/Chemical Bonding/ Disulfide bonds

WebAdenine (“A”) and Thymine (“T”) each have one donor and one acceptor, whereas Cytosine (“C”) has one donor and two acceptors, and Guanine (“G”) has one acceptor and two donors. The A nucleotides are always hydrogen bonded to T nucleotides, and C nucleotides are always hydrogen bonded to G nucleotides. WebGlycine and Proline start secondary structures called beta turns. A beta turn is a turn in the primary structure, stabilized by hydrogen bonding. Because Proline has an odd, cyclic structure, when it forms peptide bonds, it induces a bend into the amino acid chain. I challenge you to draw the peptide chain with proline; you will see it. dark deception scrapped content

WebDisulfide bond formation generally occurs in the endoplasmic reticulum by oxidation. Therefore disulfide bonds are mostly found in extracellular, secreted and periplasmic proteins, although they can also be formed in cytoplasmic proteins under conditions of oxidative stress. Weba) The disulfide bond is an ionic bond. b) Disulfide bonds can be intramolecular, but not intermolecular. c) Disulfide bonds occur in both polypeptides and nucleic acids. d) Disulfide bonds are stronger than hydrogen bonds. e) Disulfide bonds confer structural stability upon the molecules in which they form.
