How does chymotrypsin stabilize the tetrahedral intermediate?
Homework Answers
C. Electrostatic hydrogen bond interactions. A nucleophile attack on the Carbonyl group of the peptide bond causes the electron of the C=O migrate to the oxygen atom. This creates a tetrahedral structure (C-atom bound to amino group, C-alpha atom, O- atom, and the nucleophile, just like a tetrahedral CH4 molecule), the O- is stabilized by the -NH groups of chymotrypsin by hydrogen bonding.

A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
