4 biological molecules and their functions

Reactive atoms such as oxygen, nitrogen and phosphorus are present in many organic molecules. They include fats, phospholipids, steroids, and waxes. These giant molecules are also called macromolecules. 2. 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. Cells are largely composed of compounds that contain carbon. 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 structure of biological molecules. 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. Key monomers include glucose (also known as blood sugar), fructose, and galactose.. ADVERTISEMENTS: This article throws light upon the top four classes of biomolecules. Let us study them in brief. The top four classes of biomolecules are: (1) Carbohydrates (2) Lipids (3) Proteins and Amino Acids and (4) Isoprenoids and Pigments. Biological polymers are large molecules composed of many similar smaller molecules linked together in a chain-like fashion. When small organic molecules are joined together, they can form giant molecules or polymers. The individual smaller molecules are called monomers. In addition to the main proteins and nucleic acids in biological macromolecules, there are also sugars, lipids and their combined products. All Biomolecules have certain functions and these molecules all have a unique structure which is why they function in these ways. Also, read – Biomolecules in Living Organisms The large molecules necessary for life that are built from smaller organic molecules are called biological macromolecules. Biomolecules: The living matter is composed of mainly six elements — carbon, hydrogen, oxygen, nitrogen, phosphorus and sulfur. They range from small molecules such as primary and secondary metabolites and hormones to large macromolecules like proteins, nucleic acids, carbohydrates, lipids etc. There are 4 types of bio-molecules as. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Biological macromolecules are important constituents of organisms. Carbs are made of monosacharrides (single sugars) linked together. An example is starch, made of many linked glucose molecules. Start studying Functions for 4 Biomolecules. Though there are many biomolecules based on their role in body. Monosaccharides, also called monomers or simple sugars, are the building blocks of larger carbohydrate molecules and are a source of stored energy. These molecules are known collectively as macromolecules, these molecules are grouped into four main categories which each have their own structure. Food sources. These elements together constitute […] Identifying Functional Groups. Body elements; Primary metabolites; Secondary metabolites. 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. Their function is to provide a key source of energy for cells. They give energy and nutrients to all the living beings on the earth. These non-living molecules are the actual foot-soldiers of the battle of sustenance of life.
