The chirality of an amino acid results from the fact that its a carbon: A) has no net charge.
B) is a carboxylic acid.
C) is bonded to four different chemical groups.
D) is in the absolute configuration in naturally occurring proteins.
E) is symmetric.
Amino acids

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
