Lab Report: Organic Compound
Organic compound contains carbon, and is used to be thought that only living things could synthesize the complicated carbon compounds found in cells. It can be created by non- organic means. The organic compounds give protoplasm its characteristic nature; these compounds fall into four categories; protein (enzyme, catalyzes reactions, and structure), lipids (fat in cell membrane, storage of energy insulation), and carbohydrate (produces energy). Carbohydrates may exist as small as single independent units or building blocks called monomers. Carbohydrates monomers are called monosaccharides (ex; fructose, and galactose). Carbohydrates with two monomers linked together are called disaccharides (ex; maltose, sucrose, and lactose). Polysaccharides are composed of many glucose monomers (ex; starch, glycogen and cellules). Monosaccharides
When testing the five different solutions for the presence of reducing sugars using the Benedicts reagent the first step is to place water filled by a large beaker half full on a hot plate and heat the water as you prepare the rest of the experiment. Next, using a small rules, mark six test tubes (at 1 cm and 3 cm levels) and label the test tubes 1-6. Fill test tube 1 up to the 1cm mark with distilled water only. Add onion solution to test tube 2 to the 1 cm mark. In test tube 3 add potato solution to the 1cm mark. In text tube 4 place the provided glucose solution up the 1cm mark. In test tube 5 place the provided egg albumin solution up to the 1 cm mark. In test 6 place the provided egg albumin solution up to the 1cm mark. Lastly to each of the test tubes you prepared add Benedict solution to the 3 cm mark and shake gently to mix and do not cover or invert. When I first inserted distilled water the test tube was clear blue and not opaque. Test tube #2 (onion solution) turned brown/orange. Test tube #3 (potato solution) turned green and opaque. Test tube #4...
