What is the name of the carbohydrates that yield two to ten monosaccharide units?

Oligosaccharides

Carbohydrates that yield two to ten monosaccharide units are called oligosaccharides. They are a class of carbohydrates that are made up of two to ten monosaccharide units linked together by glycosidic bonds. Oligosaccharides are found in many foods, including fruits, vegetables, and grains. They can also be found in the human body, where they play a variety of roles, such as providing energy, supporting the immune system, and regulating digestion.

Some common examples of oligosaccharides include:

• Disaccharides, which yield two monosaccharide units on hydrolysis. Examples of disaccharides include sucrose (table sugar), lactose (milk sugar), and maltose (malt sugar).
• Trisaccharides, which yield three monosaccharide units on hydrolysis. Examples of trisaccharides include raffinose and stachyose.
• Tetrasaccharides, which yield four monosaccharide units on hydrolysis. Examples of tetrasaccharides include verbascose.

Oligosaccharides are classified according to the number of monosaccharide units they contain. Disaccharides are the most common type of oligosaccharide, followed by trisaccharides and tetrasaccharides. Oligosaccharides with more than four monosaccharide units are rare.
