17.
it is an aldehyde i.e CHO group in which O is doubly bonded with C i.e C=O.
in ketone also the group is CHO but the difference is that a ketonic group is never attached at the end. whereas in the ques the CHO group is attached at the end that means it is aldehyde.
in carboxylic acid the group is COOH.
in amine the group is NH3

a disulfide refers to a functional group with the structure R–S–S–R'
Disulfide bonds in proteins are formed between the thiol groups of cysteine residues by the process of oxidative folding. The other sulfur-containing amino acid, methionine, cannot form disulfide bonds.

Nucleotides are the building blocks of nucleic acids; they are composed of three subunit molecules:
a nitrogenous base,
a five-carbon sugar (ribose or deoxyribose),
and at least one phosphate group.
There is no nucleosome present in nucleotide rather it is a structural unit of a eukaryotic chromosome.
