Protein Structure

HW assignment for Biochemistry, due 9/10 at the tooth calm of class. There is an assignment in dropbox. This assignment is worth 60 points. You will need your apply or a Biochemistry intelligence to answer these questions. 1) What is the unproblematic bodily structure of a protein? The primary structure is a linear sequence of how amino group convention acids are coherent in a polypeptide mountain chain. These interactions corpse a covalent backbone. 2) wherefore isnt there exempt mutation about the peptide deposit? Because the amino nitrogen associated within the peptide fond regard has a lonely(prenominal) pair, this allows for a sonority structure to take place. With the ring structure, the group O atom corporation become nix and a three-fold bail bond between Carbon and Nitrogen can piddle. Because of this, free rotation is non favored. 3) Is there free rotation some the C?-N bond (aka the ? bond)? Why or Why not? There is not an y free rotation because the amino Nitrogen has a lone pair that can form a partial double bond character with the carbonyl group. This characteristic resists free rotation.. 4) Is there free rotation around the C?-COO bond (aka the ? bond)? Why or Why not? There is free rotation around this group because resonance is limited to resist the free rotation. 5) What is a Ramachandran plot and how does it connect to bond rotation in peptides? Ramachandran plot is a optical image method of dihedral angles ? against ? of amino acid residues in protein structure. Overall, it provides the incompatible stop possibilities of the two. 6) Which amino acid has more confining bond rotation and why? Proline is the most limiting because its side chain has a lot of hindrance. This limits the bond rotation. 7) Which amino acid has slight restrictive bond rotation and why? Glycine has the less(prenominal) restrictive bond rotation because it has the smallest side cha in. 8) What is the definition of secon! dhand structure? This happens when regions/segments of the polypeptide fold via hydrogen bonding to...If you want to jerk off a full essay, order it on our website: OrderCustomPaper.com
