Capitolo 13, Problema 45a
Identify the disaccharide that fits each of the following descriptions:
a. ordinary table sugar
Guida verificata passo dopo passo1
Understand the problem: The question asks us to identify the disaccharide commonly referred to as 'ordinary table sugar.' Disaccharides are carbohydrates composed of two monosaccharide units linked by a glycosidic bond.
Recall the common disaccharides: The most well-known disaccharides are sucrose, lactose, and maltose. Each has a specific composition and function.
Focus on sucrose: Sucrose is the disaccharide commonly known as table sugar. It is composed of one glucose molecule and one fructose molecule linked by an α(1→2) glycosidic bond.
Relate to everyday use: Sucrose is widely used as a sweetener in households and food products, making it the most likely candidate for 'ordinary table sugar.'
Confirm the answer: Based on its composition and common usage, the disaccharide that fits the description of 'ordinary table sugar' is sucrose.

Types of Disaccharides Concept 1
Sucrose
Sucrose is a specific type of disaccharide commonly known as table sugar. It is composed of one glucose molecule and one fructose molecule. Sucrose is widely used as a sweetener in food and beverages and is naturally found in many plants, particularly in sugarcane and sugar beets.

Glycosidic Bond
A glycosidic bond is a type of covalent bond that links monosaccharides together to form disaccharides and polysaccharides. This bond is formed through a dehydration reaction, where a water molecule is released. The nature of the glycosidic bond can affect the properties and digestibility of the resulting carbohydrate.
