Hexose - Wikipedia
Hexoses can form dihexose (like sucrose) by a condensation reaction that makes 1,6- glycosidic bond. When the carbonyl is in position 1, forming an formyl group (−CH=O), the sugar is called an aldohexose, a special case of aldose.
14.2: Classes of Monosaccharides - Chemistry LibreTexts
Classify monosaccharides as aldoses or ketoses and as trioses, tetroses, pentoses, or hexoses. Distinguish between a D sugar and an L sugar. The naturally occurring monosaccharides contain three to seven carbon atoms per molecule.
6.3: Classifying Monosaccharides - Chemistry LibreTexts
Monosaccharides are also classified as aldoses or ketoses to indicate the carbonyl-containing group that is present. Those that contain an aldehyde functional group are called aldoses; those containing a ketone functional group on the second carbon atom are ketoses.
14.3: Important Hexoses - Chemistry LibreTexts
Although a variety of monosaccharides are found in living organisms, three hexoses are particularly abundant: D-glucose, D-galactose, and D-fructose (Figure 14.3.1 14.3. 1). Glucose and galactose are both aldohexoses, while fructose is a ketohexose. Figure 14.3.1 14.3. 1: Structures of Three Important Hexoses.
Aldohexose - an overview | ScienceDirect Topics
Galactose is a reducing monosaccharide containing six carbon atoms (C₆H₁₂O₆), making it an hexose. Galactose is a carbon 4 (C-4) epimer of glucose, which represents the main carbon source for anaerobic energy production and glycan biosynthesis in most living organisms [ 10 ].

己糖(Hexose)化学式为C6H12O6. 1位含有醛基的6碳糖称为己醛糖， 2位含有酮基的己糖称为己酮糖。 己糖六个碳原子中有五个碳原子连上了羟基(-OH)，余下的一个碳原子是属于一个醛基(-COH)或是酮基(-CO-)的。
Aldohexose - an overview | ScienceDirect Topics
An aldohexose is defined as a monosaccharide that contains an aldehyde functional group when in the acyclic form, typically with six carbon atoms in the molecule. You might find these chapters and articles relevant to this topic. In Enological Chemistry, 2012.
