(a)
Interpretation: Whether the given statement is described as primary, secondary, tertiary or quaternary protein structure should be indicated.
Hydrogen bonding present between the amino acid in the same polypeptide results a coiled shape to the protein.
Concept Introduction: Proteins are
They polymerise by peptide linkage to form dipeptide, oligopeptide and polypeptide molecules. Each peptide bond formation is a condensation reaction that occurs with the elimination of water molecule.
(b)
Interpretation: Whether the given statement is described as primary, secondary, tertiary or quaternary protein structure should be indicated.
Hydrophilic amino acids move to the polar aqueous environment present outside the protein.
Concept Introduction: Proteins are polymeric biomolecules which are formed by the polymerisation of amino acids. Amino acids are the organic molecules with
They polymerise by peptide linkage to form dipeptide, oligopeptide and polypeptide molecules. Each peptide bond formation is a condensation reaction that occurs with the elimination of water molecule.
(c)
Interpretation: Whether the given statement is described as primary, secondary, tertiary or quaternary protein structure should be indicated.
An active protein contains four subunits.
Concept Introduction: Proteins are polymeric biomolecules which are formed by the polymerisation of amino acids. Amino acids are the organic molecules with
They polymerise by peptide linkage to form dipeptide, oligopeptide and polypeptide molecules. Each peptide bond formation is a condensation reaction that occurs with the elimination of water molecule.

- Identify the missing organic reactants in the following reaction: X + Y H+ two steps Note: This chemical equation only focuses on the important organic molecules in the reaction. Additional inorganic or small-molecule reactants or products (like H2O) are not shown. In the drawing area below, draw the skeletal ("line") structures of the missing organic reactants X and Y. You may draw the structures in any arrangement that you like, so long as they aren't touching. Click and drag to start drawing a structure.
