Based on the number of sugar units, carbohydrates are classified into three types: Monosaccharide (having single sugar molecule), disaccharide (having two sugar molecules) and polysaccharide (having more than two sugar molecules). (Glycosidic bonds are formed between two monomeric sugar units or monosaccharides.
Sucrose is a disaccharide. It is composed of two glucose units. Therefore, a glycosidic bond is formed between two glucose units during the synthesis of sucrose which makes them vulnerable to chemicals that inhibit glycosidic bond formation.
On the contrary, glucose is a monosaccharide. It does not need to have a glycosidic bond. Therefore, its synthesis is not affected by such chemicals.
why would a chemical that inhibits glycosidic bond formation affect the synthesis of sucrose but not...

What are the differences? What are these two molecules called in relation to one another? , Draw the formation of a-glucose and a P-glucose starting from the chain form using your book (page 73) as a guide, (use chemical symbols) alpha-glucose beta-glucose In equation format, draw formation...
Which of the following is true of the mechanism for Glycosidic bond formation? 1. The hydroxyl on C1 of the sugar is protonated 2. Electrons from oxygen stabilize the carbocation formed by the leaving water molecule 3. A Nitrogen from either a purine or a pyramidine attacks C1 of the sugar molecule 4. All of the above statements are true

1- Sucrose does not react with Fehling's reagent because A- Sucrose is not a reducing sugar. B) The anomeric carbon of glucose is involved in the glucose- fructose bond and hence is not free to form the aldehyde in solution. C) The monosaacharide constituents of sucrose no longer have an anomeric carbon with a free potential aldehyde or ketone group, and therefore no longer exhibits reducing properties. D) sucrose is a disaccharide of glucose and fructose in which the oxygen...
