Proteins - definitions
1.
A bond between two amino acids through dehydration synthesis.
Peptide bond
2.
The number and arrangement of multiple folded protein subunits in a multi-subunit complex.
Quaternary structure
3.
Overall 3 dimensional shape of a polypeptide. This determines the function of the protein.
Tertiary structure
4.
The area of the enzyme were the reaction happens. If the enzyme changes, this would change.

Polypeptide is:
Three or more amino acids chained together
13.
When a polypeptide chain coils or folds into a alpha helix or a beta pleated sheet.
Secondary structure
14.
A process when proteins or nucleic acids lose the quaternary structure, tertiary structure, and secondary structure which is present in their native state, by application of some external stress.
