PRODUCTION

S U G A R S

• Produced in photosynthesis

• Produced in the body as Glucose.

S T A R C H

• Produced in photosynthesis

• Glucose builds up over time during photosynthesis, so plants store it in form of starch and fiber.

CHEMICAL STRUCTURE

S U G A R

• Sugar is composed of Carbon, Oxygen, and Hydrogen

• C6H12O6

S T A R C H

• Starch is composed of Carbon, Oxygen, and Hydrogen.

• It is made up of chains of starch.

FUNCTIONSS U G A R

• Sweetener

• Quick energy release

• Adds color to biscuits and make them golden.

S T A R C H

• Provides structure

• Carbohydrate in the human diet.

• Plants use it as energy storage

SOURCES S U G A R S

• Apples

• Honey

• Bananas

• Whole wheat bread

• Sugar cane

• Sugar beet

S T A R C H

• Wheat bread

• Kernel

• Potato

NUTRITIONAL

S U G A R

• Need sugar for energy

• Too much sugar not good for body

• Stored as fat when consumed in excess

S T A R C H

• Good to consume in potato, fruits, wheat bread.

• Digestion

• Helps lower cholesterol
