What is fructosamine best defined as?

• A. A protein to which glucose binds
• B. Another term for blood glucose
• C. A carbohydrate molecule to which glucose binds
• D. A type of insulin

Answer: (A)

Fructosamine is glycated serum proteins formed when glucose binds nonenzymatically to amino groups on circulating proteins, mainly albumin. This nonenzymatic glycation creates ketoamine linkages, and because these proteins turn over over about two to three weeks, the fructosamine level reflects average blood glucose over that period rather than a single momentary value. That makes it best defined as a protein to which glucose binds. It’s not the same as blood glucose, not a carbohydrate molecule, and not a type of insulin.
