Carbohydrates
What are carbohydrates? Meaning?
Molecules that contain carbon, hydrogen and oxygen.
It means hydrated carbon.
General formula for carbohydrates?
Cx(H20)y
What is monosachride? Examples?
A single sugar unit
{ Glucose, Fructose and Ribose}
What is a disaccharide? Examples?
When two monosachrides link together
{Lactose and sucrose}
What are polysachrides? Examples?
When two or more monosachrides are linked
{Glycogen, Cellulose and Starch}
What is the chemical formula for glucose?
C6 H12 O6
What is the property of glucose molecules?
Polar
Soluble in the water
Why is it important for glucose to be soluble in water?
It allows glucose to be dissolved in the cystol of the cell.
What are the type of variations of glucose?
Beta glucose (B) Alpha glucose (A)
How/Why is glucose soluble and polar in water?
This is because of the hydrogen bonds that form between hydroxyl groups and water molecules
What type of sugar is glucose? Structure?
It is a hexose monosachride or known as a monosacride
- composed of 6 carbons
What are the structural differences between alpha and beta glucose structure?
alpha glucose has a OH attached to carbon 1 in one direction
beta glucose has a OH attached to carbon 1 in other direction
