Isolation of Casein from Milk In this experiment‚ casein was isolated from milk by means of isoelectric precipitation. A percent yield of % was obtained by the group. Introduction Milk is an opaque white or bluish-white liquid secreted by the mammary glands of female mammals‚ serving for the nourishment of their young. This liquid‚ as secreted by cows‚ goats or certain other animals are used by humans as food and as a source of dairy products such as cheese and butter. Milk composition differs

Isolation of Trimyristin from Nutmeg by Extraction Introduction: Extraction is the physical process by which a compound or mixture of compounds is transferred from one phase into another. We will be looking specifically at an organic solvent extraction which is a type of solid-liquid extraction. This type of extraction utilizes an organic solvent that has a high affinity for the compound of interest. Most reactions produce a crude mixture of undesired reagent‚ byproducts‚ as well as the

ISOLATION OF TRIMYRISTIN FROM NUTMEG ABSTRACT The purpose if the experiment was to extract the Trimyristan from ground nutmeg using extraction‚ distillation and recrystallization procedures. This experiment involves extraction and separation techniques that yield a purified product. The product was extracted and a distillation process was used to remove any remaining solvent. The recrystallization of the sample in turn produced a pure sample‚ which was proven using the known melting

Date of experiment: September 3rd‚ 2013 Organic Chemistry II – CHLB330 Name: Symone MoxeyLab Partner: Lynden Cooper Isolation of caffeine from tea leave Abstract:- Introduction:- Caffeine is probably the most commonly used addictive drug. This drug is found in a number of things ingested by people. It belongs to a group of nitrogen bases called purines. Because caffeine possesses these base-like properties‚ it is described as an alkaloid. They usually taste bitter and often are physiologically

Introduction It is crucial in the field of microbiology to study the morphology‚ biological activity‚ and the behavior of microbes thus the isolation of such microbes from the environment is necessary because it allows scientists to study them in close proximity. Microbial life forms are found everywhere. They are major players in biogeochemical cycling of elements and primary producers in numerous environments. There are also some microbes living inside higher forms of organisms that aid in digestion
