What to Focus On
- Monosaccharides are simple sugars and cannot be hydrolysed further.
- Glucose has 4 chiral centres and 16 stereoisomers.
- Most biological sugars are D-sugars.
- Lipids are hydrophobic and soluble in organic solvents.
- Fatty acids are usually made from even-numbered carbon chains.
- Fatty acids may be saturated or unsaturated.
- Amino acids have amino, carboxyl, hydrogen, and R groups around the alpha-carbon.
- There are 20 standard amino acids.
- Amino acids show L and D forms due to chirality.
Common Mistakes to Avoid
All carbohydrates are mainly used as body fuel and nothing else.
Glucose is always a straight-chain molecule and never forms a ring.
Alpha and beta anomers are the same as D and L forms.
