The given disaccharide has to be classified as a reducing or non-reducing sugar. Concept introduction: Monosaccharides and most of the disaccharides give positive test with Benedict’s solution. It is used to detect the presence of aldehyde or alpha hydroxy ketones. A positive test with Benedict’s solution is confirmed by the formation of a brick-red precipitate.

Question

What is the complete name of the following sugar? но он носн он Write out the words alpha and beta. This question is case-sensitive. Capitalize only the configuration designation, D or L, example: beta-D-glucopyranose.

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.
