In biology‚ there are four major biological macromolecules that are found in the cell‚ carbohydrates‚ lipids‚ nucleic acid‚ and proteins. Biological macromolecules are also known as organic molecules. Biological macromolecules are very large molecules that are of a key importance to living organisms. Most biological macromolecules are built by joining smaller molecule subunits. Carbohydrates are large groups of organic compounds found in foods such as sugars‚ starches‚ glucose‚ fructose‚ galactose

error in the composition of the LA agar media ingredients. However‚ when SWC agar media used‚ there was good growth of bacteria and bright production of light. When comparing both media‚ the SWC media contains 10ml of Glycerol whereas there was no Glycerol added in the LA media. Glycerol promotes good luminescent production in the bacteria. Moreover‚ the amount of Bacteriological agar as solidifying agent was increased in the SWC media

Properties of Alcohols and Phenols Experiment #3 Objectives: To observe the solubility of alcohols relative to their chemical structure‚ to perform chemical tests to distinguish primary‚ secondary and tertiary alcohols‚ and a color test for phenol. Introduction The general formula of an alcohol is ROH in which the R is an aliphatic hydrocarbon group. Alcohols may be looked upon as derivatives of water‚ HOH. One hydrogen of water is substituted by an alkyl group‚ R. Like water‚ alcohols show hydrogen

readily attained in commercial quantities from available raw materials. Organic oils are triglycerides or esters of fatty acids. They are chemical combinations of one molecule of glycerol with three molecules of fatty acids. When processed with caustic alkalis‚ they form soaps that are salts of fatty acids and glycerol‚ which is tryhydric alcohol.

researchers attempted to discover which bioplastic would be more viable for both industrial and personal use‚ in terms of its tensile strength‚ flexibility‚ water resistance and mouldability. In the procedure‚ for the first set-up‚ vinegar‚ glycerol and water were mixed in a bowl together with potato starch. The second set-up had a similar mixture‚ although instead of adding potato starch‚ agar-agar was used. Both mixtures were heated until they reached about 95 ͦC. Thereafter‚ half of the solutions

solutions of about pH10. When the pH drops below pH 8.3 phenolphthalein will go colourless. Here‚ an alkaline solution of milk‚ lipase and phenolphthalein will change from pink to colourless as the fat in milk is broken down to form fatty acids (and glycerol) thus reducing the pH to below 8.3. The time taken for this reaction to occur is affected by temperature. AIM To investigate the effects of increasing temperature on the activity of enzyme Lipase.
