Stage 1 Medicinal Chemistry – Section 1 of 6
Keywords
Prokaryote – Unicellular cells that form colonies or filaments
Cell wall – network of carbohydrates and amino acids

Flashcard Questions
What is the plasma membrane surrounded by?
Peptidoglycan layer
What is the peptidoglycan layer composed of?
Polysaccharides
polypeptides

Stage 1 Medicinal Chemistry – Section 1 of 6
What determines structure of biomolecules?
Strong bonds
If the PH is greater than the Pka between an amine and acid, which is ionic?
The acid is ionic
What happens when the PH = Pka?
A mixture of neutral and ionised compounds exist
How do dipoles come to be?
Due to differences in electronegativity
What types of molecules are involved in dispersion forces?
Temporary dipoles
Which type of molecules occasionally have even electron distribution?
Non polar molecules- this leads to no interaction
Uneven electron distribution will form temporary dipoles
What happens to a hydrogen bond when interaction is at a greater length?
They become dipole-dipole interactions, which are much stronger
What are hydrophobic interactions based on?
Entropy
What type of molecules do hydrophobic interactions involve?
Non polar molecules
Give 2 molecules that covalent bonds occur in
DNA
Polypeptides
What are ionic and hydrogen bonds in terms of biological systems?
Interaction between enzymes and small molecules

Stage 1 Medicinal Chemistry – Section 1 of 6
Which 2 compounds does water solvate?
Ions
Polar molecules
What does weak interactions between molecules aid?
Protein folding
What weakens hydrogen, ionic and dipole dipole bonds?
Water
