Definition of Starch (5)
Type of Polysacchride, Obtained, Function, Structure
- Storage Polysaccharide
- Obtained from plants
- Breaks down into glucose
- Body gains E
- In diagrams, glucose monomers have straight bonds
Also known as amalose
Definition of Insulin (3)

Definition of Amylase (2)
- Enzyme in mouth
- Breaks amylose into glucose monomers
What is interesting about cellulose in the human body?
- Not digestible because we do not have the enzyme that breaks it down
- We ingest it because it cleans out our intestines
