conjugated protein
Quick Summary
A conjugated protein is a compound formed by a protein linked with a nonprotein substance, known as a prosthetic group. This linkage can be through covalent bonds, as seen in glycoproteins and some heme proteins, or through noncovalent bonds like hydrogen bonds and hydrophobic interactions, found in lipoproteins and nucleoproteins.123
Examples of conjugated proteins include:
* Lipoproteins: Proteins combined with lipids, important for transporting fats in the blood.2
* Glycoproteins: Proteins with attached carbohydrates, playing roles in cell recognition and immune responses.3
* Metalloproteins: Proteins that bind metal ions, such as transferrin (iron carrier) and ceruloplasmin (copper carrier).4
* Hemoglobin: A conjugated protein found in red blood cells that carries oxygen.1
