Answer:Polar R groups of closely positioned amino acids often enter into "HYDROGEN BONDING".

Explanation: hydrogen bonding which is a partial intermolecular bonding interaction, is a type of bonding between a lone pair on an electron rich donor atom.

An amino acids is an organic acid, which has an amino group, carboxy group, and an organic R group. This R group can be polar or non polar. When it is polar it goes into hydrogen bonding with each other. The polar side chain which is the R chain makes an amino acids to be able to dissolve in water.

Amino acid with a Non polar R chain does not form hydrogen bond with each other.

See picture to understand the structure of an amino acid. You will see the carboxylic chain, the amino chain, and the R side chain.
