Shown is the active site if carboxypeptidase. Carboxypeptidase is a protease that works to hydrolyze the first peptide bond of a polypeptide, cleaving away the N-terminal residue from the rest of the chain. A substrate is shown in the diagram. The orange square shiwn indicates the bond that will be hydrolyzed. a) put a square around the atom that will act as a nucleophile in the first step of the mechanism. b) put a triangle around the atom that will...

Draw the Lewis structure for the following molecule. Then, using VSEPR, consider the shape around each carbon and oxygen atom. Using the shape of the electron groups around each, determine whether the resulting molecule would be polar or nonpolar. Draw methoxymethanol, CH_3OCH_2OH. The shape around the first carbon is, the shape around the oxygen, and the shape around the second carbon is molecule is (polar or nonpolar).
