Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many sugar units make up polysaccharides?
A
one
B
two
C
more than two
D
zero
Explanation: 

Detailed explanation-1: -As a rule of thumb, polysaccharides contain more than ten monosaccharide units, whereas oligosaccharides contain three to ten monosaccharide units, but the precise cutoff varies somewhat according to the convention. Polysaccharides are an important class of biological polymers.

Detailed explanation-2: -The combination of two simple sugars is called a disaccharide whereas carbohydrates consisting of three to ten simple sugars are called oligosaccharides, and those with a larger number of monosaccharide units are called polysaccharides.

Detailed explanation-3: -Simple carbohydrates are made up of just one or two sugar units, whereas complex carbohydrates are made up of many sugar units.

Detailed explanation-4: -A disaccharide (also called a double sugar ) is the sugar formed when two monosaccharides (simple sugars) are joined by glycosidic linkage.

Detailed explanation-5: -Monosaccharides are the simplest form of carbohydrates and are composed of a single molecule or subunit. The disaccharides are composed of two monosaccharides linked together, and polysaccharides are composed of 3 or more monosaccharides linked together.
