Explanation:
There are thousands of different types of molecules in a cell, but there are only four major classes of biomolecules.
It is found that more than beta dicarbonyl compounds have more than 75 % concentration in Enol form and remaining in Keto form.
Reason: This excess of Enol form can be explained due to extra stability of this isomer. It is found that the enol form is being stabilized by the interamolecular interactions i.e. Hydrogen bonding between the hydroxyl group (acting as Hydrogen Bond Donor) and Carbonyl Oxygen (Hydrogen Bond Acceptor).
