To draw the two cyclic hemiacetal forms from of glucose get the one structure hydroxyl group on ( C 4 ) place on the ring and another one structure hydroxyl group on the ( C 3 ) place on the ring. Concept Introduction: Acetal formation: The acid catalysts is added to the reaction of an alcohol with an aldehyde or ketone , the hemi-space initially formed is converted into an acetal or a ketal substitution reaction. A hemiacetal or a hemiketal: addition of alcohol to an aldehyde or ketone which produce hemi acetal.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

1) Please list all glycosidic linkages between each monosaccharide units. For example, α(1→4)2) Please discuss whether these oligo/polysaccharides would be reducing or non-reducing sugar. Remember to state your reasoning in complete sentence.

Naturally occurring D-glucose is one of a pair of enantiomers. Its mirror image is L-glucose. Draw the two cyclic six-membered isomers of L-glucose that differ in the configuration around C1 and indicate which is a and which is B.

A student decided that the configuration of the asymmetric centers in a sugar such as d-glucose could be determined rapidly by simply assigning the Rconfiguration to an asymmetric center with an OH group on the right and the S configuration to an asymmetric center with an OH group on the left. Ishe correct? (We will see in Chapter 20 that the “d” in d-glucose means that the OH group on the bottommost asymmetric center is on the right.)
