lipids on the other hand are those with fused rung compounds such as steroid and cholesterol. [8] Molecular weight can be calculated by MW= (3 x g sample)/(mol KOH) (1) Lipids of natural origin are usually obtained from their esters by alkaline hydrolysis. Such procedures allow the yield of complex mixtures of fatty acids which are resolvable with relative difficulty. Description of fatty acids therefor is restricted to the determination of its average chain length‚ average degree of unsaturation

there were trace amounts at the bottom. Overall‚ my conclusion is that only acidic solutions inhibit Amylase’s ability to digest starch. Background The goal of the experiment is to test whether or not Amylase can withstand abnormal changes in pH without denaturing itself. Salivary Amylase is an enzyme that acts upon any polysaccharide that enters the mouth (mainly starch). However‚ it has a few other clinical uses. It is used for the diagnosis of acute pancreatitis‚ an inflammation of the pancreas

What is the relationship between fats and soaps? Soaps are made from fats by hydrolysis. Fats are glycerol with three fatty acids‚ and soaps are the sodium or potassium salts of fatty acids. 10.

RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:

productexpels one of its substituents which is originallybonded to the carbonyl carbon forming a newcarbonyl compound. The reaction is callednucleophilic acyl substitution reaction.The procedure for acyl halides‚ acid anhydrides‚esters and amides is hydrolysis. Hydrolysis issimply the reaction with water to yield acarboxylic acid. Also for acetyl chloride isalcoholysis: Schotten-Bauman Reaction. It is thereaction with an alcohol to yield an ester. Thealcohol used here was ethanol. Again for acetylchloride and

reactivity tests. The samples used were acetyl chloride for acyl halide group‚ acetic anhydride for acid anhydride group‚ ethyl acetate for ester group‚ acetamide and benzamide for amide group. These derivatives were identified through the mechanism of hydrolysis‚ alcoholysis and aminolysis reactions. Positive results were obtained and the presence of a carboxylic acid derivative in each compound was confirmed. _____________________________________________________________________________________ Introduction

Introduction In this experiment‚ trimyristin will be isolated from the nutmeg by extraction‚ and then used to prepare myristic acid by hydrolysis. The isolation of a substance from a natural product is a common technique used nowadays. Usually‚ the isolation is a complex procedure and requires a lot of steps and preparation. For this experiment
