Medical Definition of IGM. 1. : a class of immunoglobulins of high molecular weight that include the primary antibodies released into the blood early in the immune response to be replaced later by IgGs of lower molecular weight and that are highly efficient in binding complement. 2. : an immunoglobulin of the class IgM.efinition of IGM. 1. : a class of immunoglobulins of high molecular weight including the primary antibodies that are released into the blood early in the immune response to be replaced later by IgG and that are highly efficient in binding complement. 2. : an antibody of the class IgM.

Polysaccharides include such substances as cellulose cellulose,chief constituent of the cell walls of plants. Chemically, it is a carbohydrate that is a high molecular weight polysaccharide. Raw cotton is composed of 91% pure cellulose; other important natural sources are flax, hemp, jute, straw, and wood......Click the link for more information.hemically, it is a carbohydrate that is a high molecular weight polysaccharide.

Glucose is the most common simple carbohydrate. Photo Credit: Image credit: Steven Berg. Carbohydrates are one of the four major classes of organic compounds in living cells. They are produced during photosynthesis and are the main sources of energy for plants and animals.The term carbohydrate is used when referring to a saccharide or sugar and its derivatives.Carbohydrates can be simple sugars or monosaccharides, double sugars or disaccharides, composed of a few sugars or oligosaccharides, or composed of many sugars or polysaccharides.t is composed of glucose and fructose. Sucrose is commonly used by plants to transport sugar from one part of the plant to another. Disaccharides are also oligosaccharides. An oligosaccharide consists of a small number of monosaccaharide units (from about two to ten) joined together.
