Key Topics to Revise
1
Chemical Analysis of Living Tissues
- Living tissues contain the same elements as Earth's crust but in different proportions
- Human body composition: Oxygen (65%), Carbon (18.5%), Hydrogen (10.5%), Nitrogen (3.3%), others (2.7%)
- Chemical analysis involves treating tissue with trichloroacetic acid to separate acid-soluble and acid-insoluble fractions
2
Amino Acids and Proteins
- Amino acids are α-amino acids with amino and carboxyl groups on the same carbon
- 20 proteinaceous amino acids are used for protein synthesis
- Classification: Non-polar, polar uncharged, positively charged, negatively charged
3
Carbohydrates
- General formula: Cₙ(H₂O)ₙ, though some exceptions exist
- Classification: Monosaccharides, oligosaccharides, polysaccharides
- Monosaccharides can be aldoses (aldehyde group) or ketoses (ketone group)
4
Lipids
- Insoluble in water but soluble in non-polar organic solvents
- Composed mainly of carbon, hydrogen, and small amounts of oxygen
- Can form emulsions - colloidal solutions in water
