Concept explainers
Interpretation:
Amino acid that is hydrophobic has to be identified and explained.
Concept introduction:
Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins.
Amino acid had both amino functional group and carboxyl functional group in a molecule.
Amino functional group is
The amino acids that are neutral are further classified into polar and non-polar.
The side chain are classified into hydrophobic (water hating) and hydrophilic (water loving).
Hydrophilic (water-loving):
The compound has the polar group such as hydroxyl group (
Hydrophobic (water-fearing):
The compound has non polar group such as alkyl chain and benzene ring is called as hydrophilic.
