a conjugated protein having a carbohydrate component
"The researchers discovered that the virus's ability to evade the immune system relied on its outer layer of glycoproteins, which function as conjugated proteins possessing a significant carbohydrate component."
A protein with covalently bonded carbohydrates.
"Researchers analyzed the glycoprotein to determine how its covalently bonded carbohydrates affected cell recognition in the immune response."
