Explain how mono-, di- and polysaccharides differ.

Answer 1

Answer to this question needs to be very long but here is a short story.

Monosaccharide is a simple sugar consist only of one unit. They serve as building blocks for more complex carbohydrate forms.

For example:

Glucose
Fructose
Galactose
Ribose and Deoxyribose - RNA, DNA
and so on...
Disaccharides are a group of sugars composed of two monosaccharide groups linked together.

For example:

Maltose = Glucose + Glucose
Sucrose = Glucose + Fructose
Lactose = Glucose + Galactose
Polysaccharides are complex carbohydrates composed of numerous monosaccharides combined through the loss of water molecules.

For example:

Starch
Amylopectin
Glycogen

Single sugar molecules are known as monosaccharides, two monosaccharide units bound together to form disaccharides, and lengthy chains of linked monosaccharide units are known as polysaccharides.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
