Chemistry - The carbon compunds that comprise the major food groups

The carbon compounds that comprise the major food groups

The outcomes of digestion of proteins, lipids and carbohydrates are
represented in the diagram above.

Human digestion is primarily the breakdown of the major nutrients: namely
proteins, carbohydrates and fats and oils (lipids). All three classes of
compounds contain carbon as the central element along with hydrogen and
oxygen. Proteins also contain nitrogen and some sulfur.

Digestion of proteins, carbohydrates and fats involves enzyme-catalysed
hydrolysis reactions where the large molecules are broken into their
simpler 'building blocks'.

* proteins are broken down to amino acids

* complex carbohydrates (polysaccharides) are broken down to glucose

* fats and oils are broken down to fatty acids and glycerol

The products of digestion are circulated to body cells where they undergo
condensation reactions to produce different proteins, complex carbohydrates
and fats.

During respiration, sugars released from the digestion of food react with
oxygen to release the energy required by cells.
