Concept explainers

Carbohydrates
Carbohydrates are the organic compounds that are obtained in foods and living matters in the shape of sugars, cellulose, and starch. The general formula of carbohydrates is Cn(H2O)2. The ratio of H and O present in carbohydrates is identical to water.
Starch
Starch is a polysaccharide carbohydrate that belongs to the category of polysaccharide carbohydrates.
Mutarotation
The rotation of a particular structure of the chiral compound because of the epimerization is called mutarotation. It is the repercussion of the ring chain tautomerism. In terms of glucose, this can be defined as the modification in the equilibrium of th…
L Sugar
A chemical compound that is represented with a molecular formula C6H12O6 is called L-(-) sugar. At the carbon’s 5th position, the hydroxyl group is placed to the compound’s left and therefore the sugar is represented as L(-)-sugar. It is capable of rotat…

Interpretation Introduction

Interpretation:

When L-ascorbic acid participates in a redox reaction, it is converted to L-dehydroascorbic acid. In this reaction, if the L-ascorbic acid oxidized or reduced should be identified and if L-ascorbic acid a biological oxidizing agent or a biological reducing agent should be explained.

Concept introduction:

Vitamin C is a water-soluble nutrient which is also recognized as ascorbic acid and present in some foods. It acts as an antioxidant in the human body and help to guard cells from the injury caused by free radicals. When body converts the food into energy the free radicals are formed.

d-(-)-Erythrose has the formula HOCH2¬CH(OH)¬CH(OH)¬CHO, and the d in its name implies that it can be degraded to d-(+)-glyceraldehyde. The (-) in its name implies that d-(-)-erythrose is optically active (levorotatory). When d-(-)-erythrose is reduced (using H2 and a nickel catalyst), it gives an optically inactive product of formula HOCH2¬CH(OH)¬CH(OH)¬CH2OH. Knowing the absolute configuration of d-(+)-glyceraldehyde (Section 5-14), determine the absolute configuration of d-(-)-erythrose.
Gentiobose is found in saffron. Gentribose contains two glucose molecules linked by a beta (1 - 6) glycosidic bond. Describe how to draw the glycosidic linkage in this structure
2-Butanone is reduced by hydride ion donors, such assodium borohydride (NaBH₄), to the alcohol 2-butanol. Eventhough the alcohol has a chiral center, the product isolated from the redox reaction is not optically active. Explain.
