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.

All carbohydrates (or carbs) are composed entirely of carbon, hydrogen, and oxygen atoms. They are often made up of a carbon spine with oxygen and hydrogen molecules, thus their name, carbo-(carbon)-hydrates(water) .They may contain ketones or aldehydes in their structure.imple Carbs (Cookies, chocolate, table sugar). The structure of carbohydrates (also called saccharides), is divided up into three major groups: Monosaccharides, Disaccharides, and polysaccharides. Monosaccharides are the simplest sugars, and make up all other carbohydrates.
