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 ( − N H 2 ) and carboxyl functional group is ( − C O O H ) and a R group is considered as side chain, when all these are bonded to same carbon atom. 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 ( OH ), acid group is called as hydrophilic. Hydrophobic (water-fearing): The compound has non polar group such as alkyl chain and benzene ring is called as hydrophilic.

Interpretation Introduction

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 (−NH2) and carboxyl functional group is (−COOH) and a R group is considered as side chain, when all these are bonded to same carbon atom.

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 (OH), acid group is called as hydrophilic.

Hydrophobic (water-fearing):

The compound has non polar group such as alkyl chain and benzene ring is called as hydrophilic.

The carbon-nitrogen peptide bond is rigid, but rotation can take place about the bond between the nitrogen and α-carbon atoms and the bond between the α-carbon and the carbonyl carbon atom. These bond angles define the conformation of the peptide chain. Consider the Ramachandran plot shown to answer both questions.
