Detailed explanation-1: -Some carbohydrates consist of hundreds or even thousands of monosaccharides bonded together in long chains. These carbohydrates are called polysaccharides ("many saccharides"). Polysaccharides are also referred to as complex carbohydrates.

Detailed explanation-2: -The second type of simple carbohydrates is disaccharides. They contain two sugar units bonded together.

Detailed explanation-3: -There are two major types of carbs: simple and complex. The difference between them lies in the number of sugar molecules they contain. Simple carbs-also known as simple sugars-contain one or two sugar molecules, whereas complex carbs have three or more.

Detailed explanation-4: -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.

Detailed explanation-5: -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.
