Study Notes
Monosaccharides and Their Characteristics
- Hexose is a monosaccharide with six carbon atoms (e.g., glucose, fructose).
- Glyceraldehyde has two enantiomers, D-glyceraldehyde and L-glyceraldehyde.
- Aldoses contain an aldehyde functional group, characterized by the presence of a carbonyl (C=O) at the end of the carbon chain.
Sugar Representations and Classifications
- Fischer projection is a representation of sugars using horizontal lines to indicate groups projecting out of the plane.
- Monosaccharides are classified based on the number of carbons: trioses (3), tetroses (4), pentoses (5), hexoses (6), and so on.
Common Monosaccharides
- Glucose is the most abundant monosaccharide and a primary energy source for living organisms.
- An example of an aldose is glucose, which features an aldehyde group.
- Fructose is an example of a ketose, characterized by a ketone group in its structure.
- Glucose is the most common monosaccharide found in nature.
General Formula
- The general formula for monosaccharides is CnH2nOn, where 'n' represents the number of carbon atoms.
