To make an ester, a hydrogen atom must be removed from the hydroxyl group (–OH) of the alcohol. The –OH portion of the acid's carboxyl group must also be removed. The hydrogren atom and the ...

The structure involves three intertwined helical polynucleotide chains. Each chain, which is formed by phosphate di-ester groups and ... about the axis of the molecule, with the pentose residues ...

DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the ...

During esterification this small molecule is water. Esters have characteristic smells and are insoluble in water. The functional group (-COO) is known as the ester link. The main use of esters is ...
