Ethanol Emulsion Test: Assignment 3 Introduction: The purpose of this lab was to test for the presence of lipids. Lipids consist of fats and oils. The test performed is called the Ethanol Emulsion test. The solubility of lipids and ethanol were broken down in this test. Lipids are non-polar organic compounds‚ making them un-soluble in water but soluble in organic solvents‚ such as ethanol. Sudan IV solution tested the oil in each sample by dying the lipids red and rising the oil to the top of the

billion worth of loans owed by ethanol producer San Carlos Bioenergy under new management headed by entrepreneur Menardo R. Jimenez. The loan restructuring was seen to help fast-track the company’s recovery from operational losses traced to the unfortunate combination of bad market conditions and government inattention. But no matter the unfortunate turn of events‚ Jimenez‚ who still owns about a third of GMA-7 television network‚ was asked to take over the bio-ethanol producer and took on the challenge

a colder room will burn more slowly. Overview Candles Candles are used to provide light when there is no electricity available or during power failures. Candles are also used to create a romantic setting at restaurants. Most candles are made of paraffin wax. Candles are also made from other types of materials such as soy wax‚ bee wax‚ plant wax or animal fat. The wax in a candle is used as fuel to keep the candle burning. The wick used in a candle is an absorbent twine and must have strong capillary

Extraction of DNA from Calf or Hog Thymus/Isolation of Yeast RNA I. Abstract Nucleic acids may be divided into two groups RNA and DNA. DNA contains almost all the genetic information while RNA serves as the bridge between the DNA and proteins. Study of both DNA and RNA initially involves proper extraction/isolation. The storehouse of eukaryotic DNA is the nucleus (and in the mitochondria)‚ so experimentally‚ DNA is extracted from tissues that have a high nuclear to cytoplasmic mass ratio‚ such

This include both nonpathogenic resident flora as well as pathogenic transient flora(Carter et al.‚ 2000). On the other hand‚ health care-associated infections constitute one of the greatest challenges of modern medicine (Mathur‚ 2011). Pandemic and avian
