What are the basic components (monosaccharides) of sucrose, maltose, lactose, glycogen, and starch?
Understand the Problem
The question asks for the basic components (monosaccharides) that make up several common disaccharides and polysaccharides: sucrose, maltose, lactose, glycogen, and starch. It also identifies glucose, fructose, and galactose as monosaccharides.
Answer
The basic components are: Sucrose (glucose and fructose), Maltose (glucose and glucose), Lactose (glucose and galactose), Glycogen (glucose), and Starch (glucose).
The basic components of the following are:
- Sucrose: glucose and fructose
- Maltose: glucose and glucose
- Lactose: glucose and galactose
- Glycogen: glucose
- Starch: glucose
Answer for screen readers
The basic components of the following are:
- Sucrose: glucose and fructose
- Maltose: glucose and glucose
- Lactose: glucose and galactose
- Glycogen: glucose
- Starch: glucose
More Information
Monosaccharides are the simplest form of sugars and are the building blocks for more complex carbohydrates like disaccharides (two monosaccharides joined) and polysaccharides (many monosaccharides joined).
Tips
It's easy to confuse the components of different disaccharides. Remembering that glucose is a common component in all three (maltose, lactose, and sucrose) can help.
