Glycoprotein

/ˌɡlaɪkoʊˈproʊˌtin/ noun

Definition

A protein that has carbohydrate groups covalently attached to it. These molecules are important for cell recognition, immune responses, and protection of cell surfaces.

Etymology

From Greek 'glykys' meaning 'sweet' (referring to carbohydrates/sugars) and 'protein'. The term emerged in the mid-20th century as biochemists discovered that many proteins, especially those on cell surfaces, have sugar molecules attached.

Kelly Says

Glycoproteins are like cellular ID cards covered in sugar! The carbohydrate portions act as identification tags that help cells recognize friend from foe, which is why blood types depend on different sugar patterns on red blood cell glycoproteins.
