A conjugated protein is a type of protein that has a non-protein molecule attached to it. These molecules can be lipids, carbohydrates, or other types of proteins. Synonyms for conjugated proteins can include glycoproteins, lipoproteins, and nucleoproteins. Glycoproteins are proteins that have sugar molecules attached, while lipoproteins are proteins that have lipids attached. Nucleoproteins are proteins that are associated with nucleic acids and are important for the structure of DNA and RNA. Other synonyms for conjugated proteins can include chromoproteins, flavoproteins, and metalloproteins, depending on the type of non-protein molecule attached to the protein. Understanding the various types of conjugated proteins is essential for understanding their biological functions.
