Carbohydrate Structure

Today students built models of carbohydrates and learned how monosaccharides join together to form di and polysaccharides.

Carbohydrates Homework Questions

1. Which elements do carbohydrates contain, and in what ratio?

2. If a sugar compound has 11 oxygen atoms, how many hydrogen atoms does it contain?

3. Based on their molecular formulas, which of the following are NOT carbohydrates?

a. C3H803
b. C10H18O9
c. C18H32O16
d. C4H8O2
e. C16H32O2
f. C6H12O6

4. For each molecule below, determine if it is a monosaccharide, a disaccharide, or a polysaccharide. You will need to look these up on your own.

a. Fructose

b. Ribose

c. Cellulose

d. Glucose

e. Sucrose

f. Glycogen

5. Describe a biological function for each of the following carbohydrates
a. Cellulose
b. Ribose
