Shmoop Biology guide to Biomolecules and the Chemistry of Life. Free online Biomolecules and the Chemistry of Life Learning Guide for teachers and students. Many of the biomolecules that we will be talking in this section are In chemical terminology, each bead is a monomer compound, the hooks. Biomolecules are the organic compounds which form the basis of life, i.e., they build up the living system and responsible for their growth and maintenance.

Our BSc Molecular Biomolecules chemistry course focuses on the structure and function of biologically important molecules, giving you a biomolecules chemistry of theoretical knowledge and practical lab skills.

You will learn about DNA, RNA and proteins and the molecular events that govern cell function while exploring the relevant aspects of biochemistry, genetics and cell biology.

Advances in molecular biology have led to the completion of several large genome projects that are changing the face of modern biology, especially in areas of medicine, agriculture and biotechnology.

You will find out how this has helped us to begin to understand the molecular basis of biomolecules chemistry and use genetic manipulation in biotechnology to make valuable products including blood clotting factors, insulin and vaccines.

Specific nature Urease catalyse the hydrolysis of urea and not biomolecules chemistry urea, so these are specific in nature.

Concentration Dilute solutions are more effective.

Amount of enzyme Very small amount can accelerate the reaction. Biomolecules chemistry inhibitors These compounds inhibit the enzyme action. With the help of such compounds, the reaction biomolecules chemistry be controlled. Enzyme streptokinase is used for blood clotting to prevent heart disease.


Pentose sugar It is either ribose or deoxy ribose not having oxygen at C2. Biomolecules chemistry base Derived from purines having two rings in their structure e. DNA and RNA Nucleic acid is polynucleotide, biomolecules chemistry in the living cells or bacterial cells having no nucleus and in viruses having no cells.


The two chains coil biomolecules chemistry double helix and run in opposite direction. These are held together by hydrogen bonding.

They are generally large and often have a complex branched connectivity. Because of their size, polysaccharides are not water-soluble, but their many hydroxy groups become hydrated individually when exposed to biomolecules chemistry, and some polysaccharides form thick colloidal dispersions when heated in water.

It successfully discriminated three brands of orange juice beverage. After cellulose, lignin is the second most abundant biopolymer and is one biomolecules chemistry the primary structural components of most plants. It contains subunits derived from p-coumaryl alcoholconiferyl alcoholand sinapyl alcohol [13] and is unusual among biomolecules in that it is racemic.

The lack of optical activity is due to the polymerization of lignin which occurs via free radical coupling reactions in which there is no preference for either configuration at a chiral center. Lipids[ edit ] Lipids oleaginous are chiefly fatty acid estersbiomolecules chemistry are the basic building blocks of biological membranes.

Another biological role is energy storage e. Most lipids consist of a polar or hydrophilic head typically glycerol and one to three nonpolar or hydrophobic fatty acid tails, biomolecules chemistry therefore they are amphiphilic.


Fatty acids consist of unbranched chains of carbon atoms that are connected by single bonds alone saturated fatty acids or biomolecules chemistry both single and double bonds unsaturated biomolecules chemistry acids. The chains are usually carbon groups long, but it is always an even number.
