There are four classes of biological molecules these include lipids, carbohydrates, proteins, as well as nucleic acids all living things are made up of one of these types of living molecules. 4 biological molecules revision notes notes for the cie igcse biology topic: 4 biological molecules these have been made according to the specification and cover all the relevant topics in the syllabus for examination in may/june as well as october/november and march.

These four types of molecules are often referred to as the molecules of life the four molecules of life are proteins, carbohydrates, lipids and nucleic acids each of the four groups is vital for every single organism on earth. A macromolecule is a very large molecule, such as protein, commonly created by the polymerization of smaller subunits ()they are typically composed of thousands of atoms or more the most common macromolecules in biochemistry are biopolymers (nucleic acids, proteins, carbohydrates and lipids) and large non-polymeric molecules (such as lipids and macrocycles. The large molecules necessary for life that are built from smaller organic molecules are called biological macromolecules 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. Four organic molecules make up all of the life on earth organic molecules contain carbon and hydrogen chemically linked to one another in long chains, with carbon as the backbone and hydrogen atoms attached to the carbon atoms. Summary notes, revision videos and past exam questions by topic for cie igcse biology topic 4 - biological molecules.
Paul andersen describes the four major biological molecules found in living things he begins with a brief discussion of polymerization dehydration synthesis is used to connect monomers into polymers and hydrolysis breaks them down again. Hydrophobic molecules 54 proteins include a diversity of structures, resulting in a wide range of functions 55 nucleic acids store, transmit, chapter 5 the structure and function of large biological molecules 69 are generally incorporated as monomers into disaccharides or polysaccharides, discussed next. Biology 12 – lesson 3 - biological molecules 4 glycogen storage form of glucose in animals and humans stored in muscle and liver cells is a highly branched large molecule when blood sugar levels drop, liver cells break down glycogen and release its glucose monomers into the blood.
Updated video on biomolecules (macromolecules): carbohydrates, lipids, proteins, and nucleic acids by the amoeba sisters including examples, functions, monomers, and structures expand details for. The information storage molecules for biological systems made of c, h, o, n & p 2 kinds of nucleic acids: dna & rna all nucleic acids are polymers of nucleotides nucleotides consist of a phosphate, a pentose sugar, and a nitrogenous base 4 different bases in dna & rna general info. The hydrophobic ends of the detergent molecules try to surround the fat globules in the milk, causing movement of the milk at the molecular level this re-orientation of the different phases of the milk cause the swirling effect we notice when the colors in the milk begin to mix.
