3. Results and discussion 3.1 Nutritional analysis In the present study‚ the potential benefits were shown by nutritional attributes of dried bathua (Table1). Moisture content and dry matter analysis‚ reporting during nutritional analysis is very important because it directly affects the nutritional content of vegetable. The moisture content was quite low (5.06%) which may be advantageous in view of increasing the sample’s shelf life. Bathua was found to be rich in carbohydrates (40.84%). There

THE CONTINUOUS BREWING OF BEER Beer is produced commercially by the controlled fermentation of wort‚ a liquid rich in sugars‚ nitrogenous compounds‚ sulphur compounds and trace elements extracted from malted barley. Fermentation is the process by which glucose is converted to ethanol and carbon dioxide and is expressed chemically as: C6H12O6 + 2PO43- + 2ADP → 2C2H5OH + 2CO2 + 2ATP Behind this simplified chemical reaction is a series of complex biochemical reactions. These reactions (known as the

There is a presence of fatty acids and sterols when the ethyl acetate extracts were analyzed. Not only is Stevia used to sweeten foods and beverages but it also is used to treat diabetes‚ lower high blood pressure‚ used as a weight loss aid‚ lowers uric acid levels‚ and prevents heartburn. Stevia increases the strength

A number of other methods can be used to synthesize the ester group. Among these are the addition of 2methylpropene to an acid to form t-butyl esters‚ the addition of ketene to make acetates‚ and the reaction

Stereochemistry of Dihydroxylation Reactions Question: Can the stereochemical outcome of dihydroxylation reactions be determined by thin layer chromatography? Overview: In this experiment‚ you will perform two reactions that transform alkenes into diols. While similar in functional group transformation‚ these reactions may lead to stereochemically different products. The two possible products are diastereomers of one another‚ and therefore have different physical chracteristics. After

Nitration of Acetanilide Introduction When organic compounds are nitrated it changes the composition and reaction of the compounds.[4] We could benefit from these changes‚ nitration of acetanilide produces a product called p- Nirtoanoline. P-Nitroaniline is commonly used as an intermediate in the synthesis of dyes‚ antioxidants‚ pharmaceuticals and gasoline. P-Nitroaniline is also used in gum inhibitors‚ poultry medicines and as a corrosion inhibitor. [2] Nitration is a type of chemical
