ANSWER: Yes, Mannose is an Aldose.
An aldose is a type of monosaccharide, or simple sugar, that contains only one carbohydrate (C6H12O6) molecule. Aldoses are characterized by the presence of an aldehyde functional group (-CHO) at the end of the molecule.
Mannose is a six-carbon aldose sugar that belongs to the family of hexoses, along with other simple sugars such as glucose, galactose, and fructose. It is found naturally in many fruits and vegetables, and is also used as a sweetener and dietary supplement.
In addition to its sweet taste, mannose has several important functions in the body. It is involved in the metabolism of carbohydrates and the synthesis of certain enzymes, hormones, and other molecules. It is also used by the immune system to identify and eliminate harmful bacteria and viruses, and has been shown to have specific benefits for the urinary tract.
