Solubility property in water should be explained when Peptide containing alanine and leucine or a peptide containing lysine and aspartic acid. Concept introduction: Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins. Amino functional group is ( − N H 2 ) and carboxyl functional group is ( − C O O H ) and a R (alkyl) group is considered as side chain, when all these are bonded to same carbon atom. In protein the amide bond can link together with two amino acids to form a peptide bond ( O = C − N H − ). Dipeptide results from the linkage of two amino acids through one peptide bond. Tertiary structure of protein is the noncovalent interaction that holds the single protein in a three dimensional shape takes place primarily between amino acid side chain or side chain thiol groups. Hydrocarbon side chain are attracted to each other by dispersion forces caused as a result of uneven distribution of electrons give rise to hydrophobic interaction. Hydrogen bonding is the electrostatic force of attraction between hydrogen and the electronegative atom.

Interpretation Introduction

Interpretation:

Solubility property in water should be explained when Peptide containing alanine and leucine or a peptide containing lysine and aspartic acid.

Concept introduction:

Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins.

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

In protein the amide bond can link together with two amino acids to form a peptide bond (O=C−NH−).

Dipeptide results from the linkage of two amino acids through one peptide bond.

Tertiary structure of protein is the noncovalent interaction that holds the single protein in a three dimensional shape takes place primarily between amino acid side chain or side chain thiol groups.

Hydrocarbon side chain are attracted to each other by dispersion forces caused as a result of uneven distribution of electrons give rise to hydrophobic interaction.

Hydrogen bonding is the electrostatic force of attraction between hydrogen and the electronegative atom.
