-Monosaccharides : the simplest carbohydrates cannot be hydrolyzed into the simpler carbohydrates. For example: Glucose, fructose (C 6 H 12 O 6 )… (Or we can say monosaccharides is a simple sugars) -All monosaccharides consist of at least three carbon atoms and they range from three to seven carbons long. -The molecule has a carbonyl group (>C=O) and multiple hydroxyl groups (—OH) Classification: Monosacchaides are classified depend on: 1. They contain an aldehyde group (–CHO) or keto group (C=O). 2. The number of carbon atoms present in the molecule: 3C : triose 4C : tetrose 5C : pentose 6C : hexose 3.Based on the configuration of chiral carbon farthest from the carbonyl group (D- or L- ) D and L designations: The –OH on the chiral atom farthest from the carbonyl group is used to assign the D and L configuration By convention, If OH on the left, then L- OH on the right, then D- nói them: Enantiomers: stereoisomers that are nonsuperposable mirror images of each other. In monosaccharides, D and L of each sugar are enantiomers
