Five things I've learned:
1. Macromolecules are polymers, they are disassembled to moners by hydrolysis. It is basically the reverse of the dehydration process.
2.A method of classifying sugars is the size of the carbon skeleton. It can range from three to seven carbons long. Glucose and fructose have six carbons which are called hexoses.
3.Polysaccharides are macromolecules. They have a few hundreds to thousands of monosacchrides that join together by glycosidic linkage.
4.Plants use starch as a storage polysaccharide. By doing so they can store up surpluses of glucose. Starch means store energy and it then translate to major cellular fuel.
5.Animals have enzymes that store starch for us and thus making starch nutrients for our cells.
