Protein Structure

HW assignment for Biochemistry, due 9/10 at the tooth fall of class. There is an assignment in dropbox. This assignment is worth 60 points. You will need your apply or a Biochemistry carry to answer these questions. 1) What is the immemorial bodily structure of a protein? The primary structure is a linear sequence of how amino group grouping acids are coherent in a polypeptide train. These interactions corpse a covalent backbone. 2) wherefore isnt there exempt trans makeation about the peptide deposit? Because the amino nitrogen associated within the peptide tie down has a lonely(prenominal) pair, this allows for a sonority structure to take place. With the vibrancy structure, the group O atom mountain become forbid and a three-fold obligate between Carbon and Nitrogen can form. Because of this, free rotation is non favored. 3) Is there free rotation several(prenominal) the C?-N bond (aka the ? bond)? Why or Why non? There is non any 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 somewhat the C?-COO bond (aka the ? bond)? Why or Why not? There is free rotation around this group because sonority 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 optic image method of dihedral angles ? against ? of amino acid residues in protein structure. Overall, it provides the antithetic stop pos sibilities 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 little restrictive bond rotation and why? Glycine has the slight restrictive bond rotation because it has the smallest side chain. 8) What is the definition of alternative structure? This happens when regions/segments of the polypeptide fold via hydrogen bonding to...If you want to pull back a full essay, order it on our website: OrderCustomPaper.com
