Most important lipids are fats‚ phospholipids and steroids Fats Made up of glycerol and fatty acids Glycerol is a 3 carbon alcohol with a hydroxyl group A fatty acid consists of carboxyl group attached to a long carbon skeleton Saturated have as many hydrogen’s as possible with no double bonds Unsaturated have one or more double bonds Phospholipids 2 fatty acids and a phosphate group attached to a glycerol The 2 tails are hydrophobic but have a

Abstract: The purpose of this experiment was to compare biodiesel to other fuels. The ecotoxicity of biodiesel was estimated‚ along with that of other biofuels through the germination of seeds in the presence of different concentrations of fuels. This resulted in biodiesel having an average of 79.4% germinated seeds in a 10% solution of fuel‚ compared to other fuels whose percentage of germinated seeds decreased with higher concentrations of fuel. In addition‚ biodiesel was also synthesized and

Biodiesel It refers to a vegetable oil- or animal fat-based diesel fuel consisting of long-chain alkyl (methyl‚ propyl or ethyl) esters. Biodiesel is typically made by chemically reacting lipids (e.g.‚ vegetable oil‚ animal fat (tallow[1][2])) with an alcohol producing fatty acid esters. Biodiesel is meant to be used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines. Biodiesel can be used alone‚ or blended with petro diesel

DNA Extraction from Wheat Germ and Making an Agarose Gel AIM: To be able to make and agarose gel and perform gel electrophoresis in six different dyes. Also‚ to extract DNA from wheat germ. INTRODUCTION: Agarose gel is a substance that is used in science for gel electrophoresis and size exclusion chromatography. These processes use agarose gel to separate and analyze proteins and DNA. The medium is composed of a purified agarose powder that has been boiled in a buffer solution and then cooled
