1.What is sugar?
Sugar is/comes from a plant (sugar cane).
2.What is the chemical formula for glucose?
The chemical formula for glucose is C6H12O6
3.What aspects of the glucose molecule contribute to taste?
The spacial arrangement of the atoms of the glucose molecule fice it a sweet taste along with the balance of the molecules.
4.How was/is sugar used the medical field?
Sugar was used for sweetener in medicines that tasted nasty.
5.What is a monosaccharide? Disaccharide? Polysaccharide?
They are "simple sugars", Their names refer to the number of units in them.
6.Draw a glucose molecule.
7.What is the difference between glucose, fructose, sucrose and lactose? What are they found in? What are their chemical formulas? What do their molecules look like?
Glucose:
8.What is an isomer?
Isomers are compounds that have the same chemical formula but different arrangements of the atoms.
9.What does the body use glucose for? What happens to the human body if glucose levels are off?
Glucose is used to fuel the brain and is constantly in the blood stream to get it to the brain. If levels are off, irregular glucose levels may result in lowered brain activity and function, and possibly a coma.
10.What other compounds are "sweet" but are unfit for human consumption? Why?
Ethylene glycol is sweet, it when in the human body, is poisonous. The oxidization of Ethylene glycol by enzymes in the human body make it poisonous to consume
11.List the artificial sweeteners discussed in the reading. Tell me a bit about each.

Glucose:
- Brain fuel
- constantly needed for proper brain function
- Has the same formula as glucose and the same amount and type of atoms, but the are arranged differently.
- It is a disaccharide, meaning it is comprised of two simple monosaccharide units a glucose unit, and a fructose unit.
- Disaccharide from one unit of glucose and one unit of galactose. Also called "milk sugar".

Saccharin:
- Fine powder
- Very sweet
- Zero calorie
- Started tasting metally
- Composed of two natural amino acids
- 200 times sweeter than glucose
- Similar structure to sucrose
- Zero calorie
