CARBOHYDRATES - Coggle Diagram
CARBOHYDRATES
THREE TYPES OF CARBOHYDRATES WITH EXAMPLES
Simple (Example: Sugar, Most boxed cereals, Tinned fruits, YoghurT, Ice cream, Jelly, Sweets/chocolates, Biscuits, Cakes)
Complex (Example: Bread, Pasta, Rice, Noodles, Oats/porridge, Breakfast cereals)
Fibrous (Example: Cauliflower, Broccoli, Green Beans, Cabbage, Brussels Sprouts, Peas, Carrots, Courgettes)
ELEMENTS OF CARBOHYDRATES
There are different types of sugar molecule but the most commonly occuring is glocuse. Glucose molecules link together in long chains to make larger molecules such as:
Starch
Energy storage molecule in plant cells.
Glycogen
Energy storage molecule in animal cells.
Cellulose
Found in plant cell walls.
Carbohydrates are our main source of energy. Carbohydrates are made from the elements carbon, hydrogen, and oxygen.
The atoms of these elements are linked together to form molecules of sugar.
FUNCTION
Carbohydrates have a main function for energy storage molecule.
They contains a large amount of energy that can be released quickly inside the body.
They are used as fuel to provide the energy for keeping the body alive.
RELEASE OF GLUCOSE INTO THE BLOOD STREAM
Simple carbohydrates easily enters the bloodstream quickly because of their simple molecular structure. Also slow down digestion.
Complex carbohydrates typically take longer to digest, processed food digested much faster.
Fiber carbohydrates are parts of plants that can't be digested.
