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…

Question

Chapter 18, Problem 18.139EP

(a)

Interpretation Introduction

Interpretation: Whether one or more galactose monosaccharide unit is/are present in sucrose has to be predicted.

Concept introduction: Sucrose is a disaccharide and it contains two monosaccharide units, Fructose and Glucose. These monosaccharide units are joined together by α,β(1→2) glycosidic linkage.

(b)

Interpretation Introduction

Interpretation: Whether one or more galactose monosaccharide unit is/are present in ribose has to be predicted.

Concept introduction: Monosaccharides are those types of sugars which cannot be further hydrolyzed. Ribose is a pentose.

(c)

Interpretation Introduction

Interpretation: Whether one or more galactose monosaccharide unit is/are present in stachyose has to be predicted.

Concept introduction: Monosaccharides are those types of sugars which cannot be further hydrolyzed. If two monosaccharides combine, then the sugar is called disaccharide. If three monosaccharides combine, then the sugar is called trisaccharide. Stachyose is a tetrasaccharide.

(d)

Interpretation Introduction

Interpretation: Whether one or more galactose monosaccharide unit is/are present in lactose has to be predicted.

Concept introduction: Lactose is a disaccharide and it contains two monosaccharide units, D-galactose and D-glucose which are joined together by β(1→4) glycosidic linkage.
