The nectar is rich in hexose sugars. Hexuronic acid is any uronic acid derived from a hexose. Hexosamines are amino sugars created by adding an amine group to a hexose. Tagatose is a sweetener based on its properties as a monosaccharide, specifically a hexose. Idose is a hexose, a six carbon monosaccharide. Hexosyltransferases are a type of glycosyltransferase that catalyze the transfer of a hexose. AHCC stood for "Active hexose correlated compound". Therefore, glucose is both a hexose and an aldose, or an aldohexose. ABC transporters generally carry oligosaccharides and have a low affinity for hexose. The NADPH is generated via the hexose monophosphate shunt. A hexokinase is an enzyme that phosphorylates hexoses (six-carbon sugars), forming hexose phosphate. A small proportion is glucuronidated, oxidised, "N"-formylated or conjugated to a hexose. Glucose is a hexose&colon; a monosaccharide containing six carbon atoms. Fucose is a hexose deoxy sugar with the chemical formula CHO. This reaction is a component of the hexose mono-phosphate shunt and pentose phosphate pathways (PPP).
