Each
amino acid has an amino and carboxyl group, in black and a unique
side chain, or radical, in blue/dark
black. |
| NON-POLAR
AMINO ACIDS. Their side chains have no charge and they do NOT
react with water, so we call them "hydrophobic "or
"water-fearing." |
 |
 |
| POLAR
AMINO ACIDS. ALL the amino acids below have side chains that
react to water. They are all "hydrophilic", or "water-loving". |
Polar but no
net charge
Asparagine is
quite polar, whilethe others are less polar or "indifferent."

These three amino
acids are basic at the pH commonly found in living things.

These two amino
acids are acidic*, (as is clear in their name) at the
pH commonly found in living things.
