Essays on Acetaldehyde

Introduction

Esophageal cancer is among the key health problems that is associated with numerous complications. As such, esophageal cancer is a form of cancer that typically occurs in any part of the esophagus and is among the most severe malignancies (Spechler, 2013). Essentially, this form of cancer is categorized into various types based of the cells involved whereby the most prevalent forms of esophageal cancer are Squamous Cell Carcinoma (SCC) as well as Adenocarcinoma (AC). Among the major risk factors that usually increase the likelihood of developing this form of cancer are smoking, having GERD (Gastro-esophageal Reflux disease), obesity and ...

Chronic alcoholism may be linked to certain types of cancers

Simply drink with moderation and care.

Alcoholism is very common for adults who consumer more than the intended amount of alcohol. Alcoholism may be acute or chronic. Acute alcoholism occurs when there is a sudden consumption of bolus amounts of alcohol in the system. In contrast, chronic alcoholism occurs when repeated abuse of alcohol is introduced in the body. Alcoholism is not limited to adults. Teenagers (mostly high school students) consume alcohol at about the same amount as with the adults. Most Americans and other Caucasians believe that ...

Abstract. Oxidation of ethanol is carried out by the oxidizing agent, potassium dichromate. The oxidizing agent undergoes a color change followed by the completion of the reaction. This change of color is utilized to measure the absorbance of the solution. The concentration of the unknown ethanol sample is calculated by plotting an absorbance vs concentration graph of the standard solutions.

Lab class completed - Introduction The aim of the experiment is to determine the concentration of ethanol by calorimetric determination method. The concentration of ethanol is measured following its oxidation with potassium dichromate. Potassium dichromate (K2Cr2O7) undergoes reduction, ...

Lab Report: Ethanol Determination Experiment

Objective: “To Determine the Ethanol content in several beverages using the enzyme alcohol dehydrogenase.”

The Chemistry behind this experiment is simple enough to understand. In the reaction carried out in the experiment, Nicotinamide Adenine Dinucleotide (NADH) is formed which can be analyzed quantitatively to find the concentration of Ethanol. The reaction involves oxidation of Ethanol to Acetaldehyde. This oxidation takes place with concomitant reduction of NAD+ to NADH. This formation of NADH can be seen in the Δ absorption at 340 nm micro level. At this wavelength, the reduced co enzyme absorbs at a very fast rate than the oxidized one, ...

Abstract

Cirrhosis is 12th on the list of leading causes of death in the US. Cirrhosis is characterized by scarring of the liver tissue due to inflammation that could lead to liver failure and death. Some patients develop cancer in due course of the illness. The scarring, which is usually permanent, covers the outer layer with collagen, makes the liver very rigid and limits the exchange of blood between the portal vein and the liver, thereby creating excess pressure in the hepatic portal vein. The scarring renders the removal of toxin such as alcohol difficult due to depletion of hepatocytes. ...
