INDUSTRIAL ANIMAL AGRICULTURE 1. Some definitions: What is ‘industrial animal agriculture’‚ and what are its properties? What are zoonoses? Industrial animal agriculture is a modern form of intensive farming that uses intensive production lines and is designed to produce the highest output at the lowest cost. Industrial farms use new technology which provides them with high mechanisation‚ speed in production and low labour requirements. The animals in industrial farms are kept usually indoors with

Experiment 9 Thin Layer Chromatography Experiment: 9 Title: Thin Layer Chromatography Introduction: Chemical analysis is conducted on specific analytes (specific substance of interest in a mixture)‚ however it is often found that these analytes must be separated for the chemical analysis to conduct their analysis. Chromatography is a set up of laboratory a technique that is used to separate a chemical mixture. This technique is very useful as it allows us to follow the course of

Analysis of an Unknown Mixture Performed: 2/13/14 Submitted: 3/3/14 Abstract: The purpose of this experiment was to separate and identify the two unknown compounds. The sample used was 105 and it contain 2-propanol and 2-heptanone. IR spectrums were taken of the contents of the second and sixth test tubes and showed the presence of an OH functional group and a small amount of ketone in test tube two and a large presence of ketone in test tube six. The average boiling points of the test tubes

WHAT IS PHARMACOGNOSY? Pharmacognosy is the study of drugs of natural origin. The term comes from two Greek words: "pharmakon" meaning drug or medicine‚ and "gnosis" meaning knowledge. The American Society of Pharmacognosy defines pharmacognosy as "the study of the physical‚ chemical‚ biochemical and biological properties of drugs‚ drug substances or potential drugs or drug substances of natural origin as well as the search for new drugs from natural sources". Plant preparations are said

Task-2 Part-2 Fibrous proteins /collagen: From my diagram I can observe the quaternary structure is 3 helical polypeptides which are looped around and is held by hydrogen bonds. The 3 stranded molecules runs parallel to others and the disulphide cross-linkages between the r-groups of the amino acid holds the molecules together forming fibres. Collagen molecules forms covalent bonds which are called cross links‚ with other collagen molecules next to it. The cross-links that form are shocked along

Intro: Carbohydrate‚ any of a large group of compounds in which hydrogen and oxygen‚ in the proportions in which they exist in water‚ are combined with carbon; the formula of most of these compounds may be expressed as Cn(H2O)n. Structurally‚ however‚ these compounds are not hydrates of carbon‚ as the formula would seem to indicate. Carbohydrates‚ as a class‚ are the most abundant organic compounds found in nature. They are produced by green plants and by bacteria using the process known as photosynthesis
