Carboydrates

Question 1

What are the 3 sugar units of carbohydrates? And give examples of each

Answer 1

1) Monosaccharides
Examples = glucose, fructose, galactose

2) Disaccharides = maltose, sucrose, lactose

3) Polysaccharide = starch, cellulose, glycogen

Question 2

What are examples of monosaccharides?

Answer 2

Glucose, fructose and Galactose

Monosaccharides include glucose, fructose, and galactose.

Question 3

What are the differences between alpha-glucose and beta-glucose?

Answer 3

Alpha-glucose has OH at the bottom, while beta-glucose has OH at the top

Alpha-glucose and beta-glucose differ in the position of the OH group.

Question 4

Which type of glucose has an easier time joining with alpha-glucose?

Answer 4

It’s easier for alpha glucose to join alpha glucose than to join beta glucose

Alpha glucose polymerization is not identical to beta polymerization.

Question 5

What is an isomer and give an example?

Answer 5

Isomer -have the same chemical formula but different structures
Glucose
Alpha glucose
Beta glucose
