Peptide
A compound made of amino acids linked by peptide bonds
1 of 10
Zwitterion
A dipolar ionic form of an amino acid that is formed by the donation of a hydrogen ion from the carboxyl group to the amino group. Because both charges are present, there is no overall charge
2 of 10
Isoelectric point
The pH value at which the amino acid exists as a zwitterion
3 of 10
Condensation reaction
A reaction in which two small molecules react together to form a larger molecule with the elimination of a small molecule such as water
4 of 10
Stereoisomers
Species with the same structural formula but with a different arrangement of the atoms in space
5 of 10
Chiral carbon
A carbon atom attached to four different atoms or groups of atoms
6 of 10
Optical isomers/enantiomers
Stereoisomers that are non-superimposable mirror images of eachother
7 of 10
Biodegradable polymer
A polymer that breaks down completely into carbon dioxide and water
8 of 10
Degradable polymer
A polymer that breaks down into smaller fragments when exposed to light, heat or moisture
9 of 10
Pharmacological activity
The beneficial or adverse effects of a drug on living matter
