Draw the tripeptide RDF. Draw the structure that would exist at physiological pH. For the peptide bond between R and D, identify in your drawing all the atoms that are co-planar by coloring them in red. All atoms for every amino acid must be explicitly drawn.
Neutral Amino Acids
Amino acids which do not have any charge on them are neutral amino acids.
Globular Protein
The globular proteins refer to the shape of protein specifically spherical in nature apart from spherical form fibrous, disordered and membrane-bound proteins exist. These globular proteins are miscible in water and form a colloidal solution rather than other types which might not exhibit solubility. Many classes of the fold are found in globular proteins, which render them a sphere shape. Globular fold containing proteins usually are referred to by the term globin.
Dimer
Dimers are basic organic compounds, which are derivates of oligomers. It is formed by the combination of two monomers which could potentially be strong or weak and in most cases covalent or intermolecular in nature. Identical monomers are called homodimer, the non-identical dimers are called heterodimer. The method by which dimers are formed is known as “dimerization”.
Dipeptide
A dipeptide is considered a mixture of two distinct amino acids. Since the amino acids are distinct, based on their composition, two dipeptide's isomers can be produced. Various dipeptides are biologically essential and are therefore crucial to industry.
Draw the tripeptide RDF. Draw the structure that would exist at physiological pH. For the peptide bond between R and D, identify in your drawing all the atoms that are co-planar by coloring them in red. All atoms for every amino acid must be explicitly drawn.
- Amino acid:- It maybe defined as the compounds which contain an amino(-NH2) group, a carboxyl (-COOH) group and a side chain (-R) which varies for every amino acid.
- Tripeptide:- Peptide means bond between carbonyl carbon (-C=O) and the amino (-NH) group.
that is(i.e.), 
is a peptide bond.
- And three amino acids combines to form a tripeptide.
- Physiological pH:- It is the pH where net charge becomes zero by making balance between acid and base.
- R is Arginine, D is Aspartic acid and F is Phenylalanine.
