- Biological Molecules
- Water
- Polar
- Metabolite
- Solvent
- High heat specific capacity
- Relatively large latent heat of vaporisation
- Strong cohesion between molecules
- Ice is less dense than water
- Carbohydrates
- Only carbon, hydrogen and oxygen
- Long chains of sugars, saccharides
- Monosaccharaides
- Can join to form disaccharides and polysaccharides
- Glycosidic bonds, condensation reactions
- Can join to form disaccharides and polysaccharides
- Monosaccharaides
- Monosaccharides
- Glucose
- Main substrate for respiration
- Two isomers - alpha and beta
- Glucose
- Glycogen
- Animal energy storage
- Lipids
- Only soluble in organic solvents
- Saturated
- Animal fats
- Don't contain double bonds
- Solid at room temperature
- Unsaturated
- Plants
- Double bonds
- Liquid at room temperatre
- Triglycerides
- One glycerol. three fatty acids
- Energy reserves in plants
- Ester bonds
- Phospholipids
- One fatty acid in triglyceride replaced by phosphate group
- Hydrophilic head, hydrophobic tail
- Proteins
- Amino acids
- Peptide bond
- Primary structure
- Order of amino acids
- Secondary structure
- Alpha helix or beta pleated sheet
- Tertiary structure
- 3D shaoe
- Globular or fibrous
- 3D shaoe
- Amino acids
- Inorganic ions
- Hydrogen - pH
- Iron ions - haemoglobin
- Sodium ions - co-transport of glucose
- Phosphate ions - component of DNA
- Water
- Monomers and Polymers
- Monomers
- Monosaccharides
- Glucose
- Nucleotides

- Water
- Polymers
- Monomers joined together
- Condensation reaction
- Joins monomers together, removes water
- Hydrolysis
- Water is added, monomers seperate
- Monomers
