- Stereoisomers
- Stereoisomers are molecules that
have molecular formula and atomic
bondage but different arrangement in
space.
- Optical Isomerism
- In order to exhibit optical
isomerism your need to have a
chiral centre it is usually a carbon.
Chiral means four different atoms or
groups are attached to it
- Enantiomers
- Enantiomers are
chiral molecules
that mirror
eachother and are
furthermore non
superimposable.

- Amino Acids
- Amino acids are bifunctional molecules, they
contain both the amino group (-NH₂) and a
carboxyl group (-COOH). When both functional
groups are attached to the same carbon the
amino acid is called an α-amino acid

- Zwitterions
- Amino acids can act as both weak
acids and weak bases. The (-COOH)
group donates a H⁺ ion while the
(-NH₂) group accepts the H⁺

- Structure of Proteins
- Primary
- The order in which amino
acids join together are
primary structures
- The order in which amino
acids join together are
primary structures
- Secondary
- When a polypeptide chain
forms a alpha helix or a
beta sheet
- When a polypeptide chain
forms a alpha helix or a
beta sheet
- Tertiary
- Tertiary structures require four types of
interactions to maintain its structure.
-Instantaneuos dipole-Induced dipole
between non-polar side chain, -Hydrogen
bonds between polar side chains, -Ionic bonds
between ionisable side chains, - Sulfide
bridges between covalent side chains
