Document Summary
Are aldehyde or ketone derivatives of polyhydroxy alcohols (c-h2o)n = carbon hydrate, n = 3-8. Each c has an oh group except for one which has a carbonyl group. N= 4, tetroses n= 5 pentoses n= 6 hexoses n= 7 heptoses. An aldopentose indicates an aldose sugar consisting of a five-carbon chain. If the carbonyl group is an aldehyde, sugar is an aldose. If the carbonyl group is ketone, sugar is a ketose. Structural isomers: same molecular formula, different structural formula. Stereoisomers: same molecular formula, same structural formula but different configurations or arrangements of groups in space. Carbon called asymmetric c or chiral c cis/trans configurations. Different optical configurations 2 different arrangements of 4 different groups around a central c. Converts a 3d (tetrahedral) object into a 2d form for simplicity in viewing. Reference molecule for d and l configurations is glyceraldehyde.
