Biological macromolecules are large cellular components abundantly obtained naturally and are responsible for varieties of essential functions for the growth and survival of living organisms. There are four important classes of biological macromolecules, viz., carbohydrates, lipids, proteins, and nucleic acids.

Macromolecules are large complex molecules that occur in colloidal state in intercellular fluid. They are formed by the polymerization of low molecular weight micromolecules. Polysaccharides, proteins, and nucleic acids are common examples of macromolecules.

Biological macromolecule A large, organic molecule such as carbohydrates, lipids, proteins, and nucleic acids.

Macromolecules are the molecules of life and are built around chains of carbon atoms that are often quite long. Explain why carbon's structure allows it form molecules essential for life. Carbon is the most important element to life. Without this element, life as we know it would not exist.

A macromolecule is a very large molecule important to biological processes, such as a protein or nucleic acid. It is composed of thousands of covalently bonded atoms. Many macromolecules are polymers of smaller molecules called monomers.

11.1 Introduction: The Four Major Macromolecules These are the carbohydrates, lipids (or fats), proteins, and nucleic acids. All of the major macromolecule classes are similar, in that, they are large polymers that are assembled from small repeating monomer subunits.

Macromolecules For Identification. All living things contain organic macromolecules: Lipids, proteins, carbohydrates and nucleic acids. Characteristic for these organic molecules is that they are made up of only a small number of elements: Carbon, hydrogen, oxygen, and to smaller amounts nitrogen, phosphorus and sulfur ...
