Organic molecules are the molecules of life that include Carbon and Hydrogen. Organic molecules consist of four important classes which are lipids‚ carbohydrates‚ proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing

This study focuses on the effect that temperature has on the enzyme amylase. Enzymes are composed of proteins and acts as a catalyst to speed up the rate of a specific chemical reaction by lowering the activation energy. Reactions do not need enzymes to occur‚ but the human body and other living organisms depend on the use of enzymes in order for biochemical reactions to happen in milliseconds. Each enzyme contains a distinct three dimensional structure which is related to its particular function

Cardiovascular Diseases Cardiovascular disease is defined as a disease that affects any area of the cardiovascular system‚ including the heart and blood vessels‚ and covers a range of diseases such as arteriosclerosis‚ atherosclerosis and coronary heart disease. Diet plays a vital part in the prevention and control of these diseases however other manageable factors such as smoking and physical inactivity also contribute to the diseases if not controlled correctly. However corrective action or

Match the following terms to the correct statement. a. Independent Variable b. Control Group c. Dependent Variable The control group is the part of the experiment where the independent variable being tested is not so that it may serve as a standard for comparison. In an experiment it is the independent

Environmental Chemistry It often matters how much given atoms combine‚ in what arrangement‚ with what others‚ what impulse they receive‚ and what impart. The same ones make up earth‚ sky‚ sea‚ and streams; the same as the sun‚ the animals‚ grains and trees‚ but mingling and moving in every different ways. - Lucretius (95-52 B.C.) in The Nature of Things I. Physical Chemistry Why is Physical Chemistry important in the study of Environmental Engineering? • Applied physical chemistry procedures

SOLVENT EXTRACTION Solvent extraction‚ also known as liquid extraction and partitioning‚ is a method to separate compounds based on their relative solubility in two different immiscible liquid‚ usually water and organic solvent. It is an extraction from one liquid phase to another liquid phrase. Liquid extraction is a basic technique in chemical laboratories‚ where it is performed using a separator funnel. This type of process is commonly performed after a chemical reaction as part of the work-up
