Concept explainers
(a)
Interpretation:
The type of protein that describes the given statement “In the amino acid, the interaction of R groups results in formation of disulphide bonds or ionic bonds” needs to the determined.
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:
The type of protein that describes the given statement “In the polypeptide chains the amino acids are joined by peptide bonds” needs to the determined.
Concept Introduction:
Proteins are polymeric biomolecules which are formed by the polymerisation of amino acids. Amino acids are the organic molecules with –NH2 and −COOH functional groups bonded on same carbon atom of the molecule.
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:
The type of protein that describes the given statement “In the beta-pleated sheet the polypeptides have hydrogen bonding interactions with the polypeptides in adjacent chains” needs to the determined.

- Please correct answer and don't use hand ratingarrow_forwardPlease correct answer and don't use hand ratingarrow_forwardThe SN 1 mechanism starts with the rate-determining step which is the dissociation of the alkyl halide into a carbocation and a halide ion. The next step is the rapid reaction of the carbocation intermediate with the nucleophile; this step completes the nucleophilic substitution stage. The step that follows the nucleophilic substitution is a fast acid-base reaction. The nucleophile now acts as a base to remove the proton from the oxonium ion from the previous step, to give the observed product. Draw a curved arrow mechanism for the reaction, adding steps as necessary. Be sure to include all nonzero formal charges.
