Document Summary
Plants take sunlight and they make sugar and oxygen, we take in that sugar and oxygen to power glycolysis and cellular respiration and make energy molecules like atp. Monosaccharides: the monomer, we need n to be more than or equal to 3, triose, they all have a carbonyl group. The position os the carbonyl differentiates the kind of carbohydrate they are: and one or more hydroxyl group, two major classes (tautomers): Ends with ulose : the number of carbons also helps with naming, definitions of stereochemistry: Rules for assigning the side chain stereochemistry is the same as amino acids. Aldose: the carbons between the ends can all be chiral. Any of the chiral centres are not equivalent between the two steriomers. When the stereoisomers are not mirror images. Sometimes the sugar prefers being in a ring structure. The chiral carbon farthest from the anomeric carbon is used for the d/l.
