While some of these substances are macromolecules, most of them have complex structures that cannot be directly absorbed by intestinal cells. The digestive process consists of breaking down these food materials into smaller molecules that can be absorbed.<br /><br />Hydrolysis, the process by which chemical bonds are broken by the addition of a molecule of water, is the basic chemical reaction by which these molecules are split into their constituent, smaller molecules. Interestingly, although proteins, carbohydrates and fats are vastly different in their structures and make up, it is the same chemical reaction, hydrolysis, that is required for their break down during the chemical digestion process.Anonymoushttps://www.blogger.com/profile/18318793357205752287noreply@blogger.comtag:blogger.com,1999:blog-6940012124110345593.post-70862444927962063812012-06-09T08:03:35.030+08:002012-06-09T08:03:35.030+08:001.
