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 ...

"It unlocks a new dimension of chemical synthesis ... "C-H bonds are incredibly strong, and the natural structure of ketones and esters makes it especially difficult to direct a catalyst to ...

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 ...

Fat molecules contain three ester ... Each molecule consists of a long non-polar covalent hydrocarbon ‘tail’ and a polar, ionic ‘head’ where the charge is. This structure explains the ...
