Macromolecules In The Sandwich

In the sandwich you just ate, you have consumed three raw macromolecules. The bread would be considered the carbohydrate. The mayonnaise is the lipid. The turkey is of course considered the protein. Although the body takes in these three different forms one way, the way the body breaks it down is in three ways. First is the break-down of the carbohydrates(bread). The polysaccharide form of this is too big for the body to simply break down directly. So, instead the body uses multiple forms of procedures to break down the molecule into a usable size, such as glucose. The body begins breaking it down with salivary amylase. This is the process of chewing it in your mouth. The disaccharides then go through intestinal digestion which break them down
