Study Notes
Characteristics of Penicillins
- One characteristic of penicillins is that they inhibit bacterial cell wall synthesis.
Function of Penicillins
- The main function of penicillins is to inhibit bacterial cell wall synthesis, ultimately killing the bacteria.
New Forms of Penicillin
- New forms of penicillin have been developed through genetic engineering and other techniques.
Determining Enzyme and Receptor Sites
- X-ray crystallography has enabled biochemists to determine the precise structure of enzymes and receptor sites.
Pharmacological Activity
- The pharmacophore is the composition of the structural fragment of a drug molecule that confers pharmacological activity.
Orientation of Functional Groups
- The functional groups in a drug molecule are oriented in a specific three-dimensional arrangement to interact with the receptor site.
