Cyclic Structure of Fructose As a ketohexose, fructose forms a 5-membered ring when the hydroxyl on C-5 reacts with the carbonly on C-2 -D-Fructose.
Biological Macromolecules
Four major groups of organic compounds, necessary for life are: polymers monomers –Carbohydrates monosacchrides –Lipids fatty acids –Proteins amino acids.
