What is a polysaccharide?

Short Answer

Expert verified

A polysaccharide is a carbohydrate that contains many monosaccharides.

Step by step solution

01

Introduction

  • Carbohydrates are the simple constructing blocks of all residing things. Carbon(C), Hydrogen(H), and Oxygen (O)atoms are located in diverse combos in all carbohydrates. Carbohydrates are sugars.
  • Monosaccharides and disaccharides are the 2maximum not unusual place sugar kinds.
02

Polysaccharides

  • A polysaccharide is a carbohydrate composed of many monosaccharides bound together by glycosidic linkages.
  • Monosaccharide chains shape polysaccharides.
  • As a result, each polysaccharide is made up of several chemical rings.
  • Because a water molecule is generated for every glycosidic link, condensation polymerization is used to build polysaccharides.
03

Properties of Polysaccharides

  • Polysaccharides have a sour flavor and are water-insoluble.

  • Polysaccharides encompass starch and cellulose.

  • Polysaccharides are carbohydrates composed of several monosaccharides connected together by glycosidic linkages.
  • Non-reducing carbohydrates are polysaccharides.
  • Polysaccharides have branching and complicated structures.
