INTRODUCTION
Molecule: chemical structure made of atoms
Compound: chemical substance made of atoms from 2+ elements
Anabolic process: process where something is built up (using smaller molecules to create a
larger one)
Catabolic process: process where something is broken down (from larger molecules to smaller
ones)
, 2
ORGANIC COMPOUNDS
All made from Carbon, Hydrogen, and Oxygen (CHO)
Carbohydrates
Made from:
● Carbon
● Hydrogen
● Oxygen
Functions:
● Stores energy
● Provides energy
● Provides protection and structure
1. Monosaccharides
(1 sugar molecule)
Energy source.
Types and sources [Can be remembered as GGF (Gives Good Flavour)]:
● Glucose
○ Test: Benedict’s solution
■ Positive = brick red colour
■ Negative = blue colour
● Galactose
● Fructose
