The c 2 epimer of glucose
網頁D-mannose, a C-2 epimer of glucose, exists naturally in many plants and fruits, and is found in human blood at concentrations less than one-fiftieth of that of glucose. However, although the roles of glucose in T cell metabolism, diabetes and obesity are well characterized, the function of D-mannose in T cell immune responses remains unknown. 網頁The configuration of the C-2 epimer of D-glucose is: Q.

Glucose is an aldohexose that crystallizes in an anhydrous form in absolute alcohol and has a density of 1.52 g/mL. It is highly soluble in water and alcohol. It hydrates easily and loses this water slowly when heated to 100°C. Anhydrous glucose melts slowly at a temperature of 146°C.
