Lipids play various roles in biological systems:
Highlight: The presence of double bonds in unsaturated fats creates "kinks" in the fatty acid chains, affecting their physical properties such as melting point.
The circulatory system is essential for multicellular organisms:
Definition: Diffusion - The movement of particles from an area of high concentration to an area of low concentration.
This section of the AS biology unit 1 revision notes lifestyle health risk pdf provides a comprehensive overview of key biological molecules and systems, essential for understanding the foundations of biology at the AS level.
Polysaccharides are long chains of glucose molecules with specific structures and functions:
Glycogen:
Starch:
Cellulose:
Definition: Condensation reaction - A chemical reaction in which two molecules combine to form a larger molecule, releasing water in the process.
Lipids, particularly triglycerides, are another important class of biomolecules:
Vocabulary: Ester bond - A chemical bond formed between a fatty acid and glycerol in triglycerides.
Fatty acids can be:
Example: Olive oil contains monounsaturated fats, while fish oils are rich in polyunsaturated fats.
Water is a crucial molecule in biology due to its unique properties. Properties of water A level Biology include:
Highlight: These properties make water essential for life, allowing for processes like photosynthesis and maintaining stable temperatures in organisms.
Carbohydrates are vital biomolecules composed of carbon, hydrogen, and oxygen. They are classified into:
Example: Glucose, fructose, and galactose are examples of monosaccharides, while maltose, sucrose, and lactose are disaccharides.
Carbohydrates serve important biological functions:
Vocabulary: Glycosidic bond - A chemical bond that joins carbohydrate molecules together.
