What to Focus On
- Carbohydrates are polyhydroxy aldehydes or ketones.
- Classified as monosaccharides, disaccharides, and polysaccharides.
- Monosaccharides form cyclic structures (α and β anomers).
- Proteins are polymers of α-amino acids linked by peptide bonds.
- 20 amino acids form proteins; 10 are essential.
- Four levels of protein structure: primary, secondary, tertiary, quaternary.
- Lipids are water-insoluble, organic solvent-soluble biomolecules.
- Fats are saturated triglycerides; oils are unsaturated.
- Waxes are esters of long-chain alcohols and fatty acids.
Common Mistakes to Avoid
DNA and RNA are structurally the same except for the sugar.
All carbohydrates are sugars and taste sweet.
Peptide bond is formed by the combination of any two amino acids without water loss.
Memory Tips
Definition of carbohydrates: polyhydroxy aldehydes or ketones
Classification of monosaccharides: Aldotriose, Aldotetrose, Aldopentose, Aldohexose
D-glucose and D-fructose are hexoses with 6 carbons
Monosaccharides: Monosaccharides cannot be hydrolyzed further
