A disulfide refers to a functional group with the structure R−S−S−R′. The linkage is also called an SS-bond or sometimes a disulfide bridge and is usually derived by the coupling of two thiol groups.

A phosphodiester bond occurs when exactly two of the hydroxyl groups in phosphoric acid react with hydroxyl groups on other molecules to form two ester bonds. Phosphodiester bonds are central to all life on Earth, as they make up the backbone of the strands of nucleic acid.

salmanssj: what is thiol group
kalpraj1: A thiol group is a fuctional group containing a sulfur atom bonded to a hydrogen atom. General formula: -SH

Also Known As: sulfanyl group, mercapto group

Examples: The amino acid cysteine contains a thiol group.

Disulphide bonds are used to connect peptide A and B of insulin

This was from biology point of view.

We have not yet discussed about phospho diether bond in bio
But if its di phospho ester then the answer is
-its used for the connection between two nucleotide of DNA
