Concept explainers
(a)
Interpretation:
The structure of two possible dipeptides that can be formed by the combination of glycine and asparagine amino acids should be drawn.
Concept Introduction:
Proteins are
These amino acids involve in condensation process to form peptides and polypeptides which further form complex protein molecules.
(b)
Interpretation:
The N and C-terminal amino acids in the dipeptides that can be formed by the combination of glycine and asparagine amino acids should be labeled.
Concept Introduction:
Proteins are biomolecules that are composed of certain monomer units such as amino acids. These are carboxylic acids with one amino group bonded on the alpha-C atom of the molecule.
These amino acids involve in condensation process to form peptides and polypeptides which further form complex protein molecules.
(c)
Interpretation:
The name of the dipeptides that can be formed by the combination of glycine and asparagine amino acids, using three letters symbol should be determined.
