Why are carbohydrates deemed a high energy source?

They contain high energy electrons (H atom associated)

2

How do carbohydrates provide structure within animal cells?

The make up the extra-cellular matrices of animal cells

3

What are Monosacharides ?

6 carbon hexoses (individual molecules)

4

Name 3 Monoscharides

Glucose
Galactose
Fructose

5

What is a Disaccharide ?

Formed from monomers (multiple Monosacharides stuck together) via Glycosidic bonds.

6

Name 3 Disaccharides

Maltose
Lactose
Sucrose

7

What is a Glycosidic bond ?

Hydroxl group + Carbon of monomer.

Which of the three main Disaccharides is reducing and non-reducing ?

Maltose-Reducing (can be oxidized)
Lactose-Reducing
Sucrose-Non-reducing

9

What are Polysaccharides ?

Very large molecules consisting of hundreds of monomers all connected to one another.

10

What are the two 2 types of Glucose polymer found in Starch ?

Amylose & Amylopectin

11

Combined what do Amylose & Amylopectin create ?

Alpha Helices
