All Biomolecules have certain functions and these molecules all have a unique structure which is why they function in these ways. When small organic molecules are joined together, they can form giant molecules or polymers. ADVERTISEMENTS: This article throws light upon the top four classes of biomolecules. Start studying Functions for 4 Biomolecules. 2. The structure of biological molecules. Let us study them in brief. Also, read – Biomolecules in Living Organisms Though there are many biomolecules based on their role in body. Carbs are made of monosacharrides (single sugars) linked together. They range from small molecules such as primary and secondary metabolites and hormones to large macromolecules like proteins, nucleic acids, carbohydrates, lipids etc. Food sources: These are the substances which act as food materials. They not only have biological functions but also have large molecular weights and complex structures. Biological polymers are large molecules composed of many similar smaller molecules linked together in a chain-like fashion. In addition to the main proteins and nucleic acids in biological macromolecules, there are also sugars, lipids and their combined products. The large molecules necessary for life that are built from smaller organic molecules are called biological macromolecules. Lipids: Lipids are nonpolar molecules that are not soluble in water. These giant molecules are also called macromolecules. Monosaccharides, also called monomers or simple sugars, are the building blocks of larger carbohydrate molecules and are a source of stored energy. They include fats, phospholipids, steroids, and waxes. Reactive atoms such as oxygen, nitrogen and phosphorus are present in many organic molecules. They give energy and nutrients to all the living beings on the earth. There are 4 types of bio-molecules as. An example is starch, made of many linked glucose molecules. These non-living molecules are the actual foot-soldiers of the battle of sustenance of life. Biomolecules: The living matter is composed of mainly six elements — carbon, hydrogen, oxygen, nitrogen, phosphorus and sulfur. The study of how carbon atoms interact with other atoms in molecular compounds forms the basis of the field of organic chemistry and plays a large role in understanding the basic functions of cells. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Their function is to provide a key source of energy for cells. Cells are largely composed of compounds that contain carbon. These molecules are known collectively as macromolecules, these molecules are grouped into four main categories which each have their own structure. Body elements; Primary metabolites; Secondary metabolites. There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. The top four classes of biomolecules are: (1) Carbohydrates (2) Lipids (3) Proteins and Amino Acids and (4) Isoprenoids and Pigments. Start studying 4 Major Biological Molecules. Because the chemical behavior of many reactive atoms or groups of atoms is well characterized, the presence and position of specific functional groups on an organic molecule can be used to predict the chemical behavior of that biomolecule.
