About Conjugated Molecules
Conjugated molecules contain a non-protein component attached to a protein portion, giving the molecule properties that a simple protein lacks. The content includes glycoproteins, lipoproteins, phosphoproteins, nucleoproteins, chromoproteins and metalloproteins, with attention to their prosthetic groups and roles in transport, protection, catalysis and cellular structure.
