A ketohexose, in contrast, is a hexose with a ketone functional group located in position 2. Aldohexoses have four chiral centers. Because of that there are 16 possible stereoisomers. Examples of aldohexoses are glucose, mannose, galactose, gulose, idose, talose, allose, and altrose. Glucose is a one of the products of photosynthesis in plants.

Hexoses. The three hexoses are D-glucose, D-galactose, and D-fructose (Figure 7.2.1 7.2. 1 ). Glucose and galactose are both aldohexoses, while fructose is a ketohexose. Figure 7.2.2 7.2. 2: Structures of Three Important Hexoses. Each hexose is pictured with a food source in which it is commonly found.

A ketohexose is a ketone-containing hexose. The important ketohexoses are the 2-ketohexoses, and the most important 2-ketose is fructose. Besides the 2-ketoses, there are only the 3-Ketoses, and they do not exist in nature, although at least one 3-ketohexose has been synthesized, with great difficulty.

D-Tagatose (Tag) is a ketohexose that is a C-4 epimer of d-fructose and a low-calorie natural sugar present in small amounts in fruits and milk products. d-Tagatose can easily replace the sucrose in food, since their taste, cooking, and texture properties are very similar.

For example, and aldopentose is a five-carbon sugar with an aldehyde carbonyl; a ketohexose is a six-carbon sugar with a ketone carbonyl: However, it is important to keep in mind that the carbonyl groups of sugars usually are combined with one of the hydroxyl groups in the same molecule to form a cyclic hemiacetal or hemiketal. These structures.

D-Fructose, also shown in Figure 14.3.1 14.3. 1, is the most abundant ketohexose. Note that from the third through the sixth carbon atoms, its structure is the same as that of glucose. It occurs, along with glucose and sucrose, in honey (which is 40% fructose) and sweet fruits. Fructose (from the Latin fructus, meaning "fruit") is also.

Important Hexoses. Although a variety of monosaccharides are found in living organisms, three hexoses are particularly abundant: D-glucose, D-galactose, and D-fructose (Figure 6.4.1 6.4. 1 ). Glucose and galactose are both aldohexoses, while fructose is a ketohexose. Figure \ (\ PageIndex {1}\): Structures of three important h exoses: D-glucose.

Putting it all together, glucose is an aldohexose, a six-carbon aldehyde sugar; fructose is a ketohexose, a six-carbon keto sugar; ribose is an aldopentose, a five-carbon aldehyde sugar; and sedoheptulose is a ketoheptose, a seven-carbon keto sugar. Most of the common simple sugars are either pentoses or hexoses.

Fructose is a ketohexose found in honey and a wide variety of fruits and vegetables. Combined with glucose in an α (1→2)β linkage, it forms sucrose. It makes up one-sixth to one-third of the total carbohydrate intake of most individuals in industrialized nations. Sorbitol, a sugar alcohol, is a minor dietary constituent.

D-Tagatose (D-tag) is a ketohexose, a stereoisomer of d-fructose and it is found naturally in several foods, including cheese and yoghurt. Its texture is very similar to sucrose and almost as sweet as sucrose, with only 1.5 kcal/g and it does not provoke dental caries (Levin 2002 ; Oh 2007 ; Taylor et al. 2008 ; Calzada-León et al. 2013 ).
