Are there any differences in the rate of metabolism of a dried yeast culture with differing carbohydrate sources? In the current practical that was undertaken the growth rate of yeast (S. cerevisiae) with differing carbohydrates sources : Glucose (C6H12O6)‚ Fructose (C6H12O6)‚ Lactose (C12H22O11)‚ Xylitol “(CHOH)3(CH2OH)2” and Water (H2O) as a Control were observed. “ Yeast are single-celled fungi which consist of more than one thousand different species which have been identified. The most commonly

difficult and costly task‚ compared with such charged molecules as metallic ions. Here is an example for isolating sucrose from Euphorbia lathyris L. (EL). 4. What is the best way to detect sugars? To overcome the high detection limit of carbohydrates‚ most of the methods described in the literatures rely on some sort of derivatization technique since the introduction of a chromophoric moiety can substantially improve the sensitivity‚ and a suitable tagging of reducing saccharides usually results

variety of foods. There are five basic food groups and I will outline them and their function in the body. One basic food is bread‚ other cereals and potatoes and the main nutrient for this type of food is carbohydrate‚ calcium‚ iron‚ B vitamins and dietary fibre. The main function of carbohydrate in the body is to provide energy. Dietary fibre is not absorbed but passes through the gastrointestinal tract‚ helping to keep it healthy before being excreted. The role of calcium is to develop and maintain

use of glucose during physical activity are: diet‚ activity intensity level‚ and activity duration. (Whitney and Rolfes 466-468) First of all you must have a carbohydrate rich diet in order to store glycogen. Abundant glycogen stores enables people to perform physical activity longer at higher intensity. Glucose provided by carbohydrates (Whitney and Rolfes 466-468) Intensity of activity affects glucose use because a lower intensity saves glucose while high intensity burns glucose quickly. Moderate

Brown rice vs. White rice: Which is better? Rice is considered a staple diet all over the world. With over billions of people consuming it daily‚ the question remains which is better out of these two? We all know or must have heard that brown rice is healthier as compared to white rice. Now‚ let us read about it in detail as to how brown rice is healthier? But before that‚ let us clarify the physical difference between these two rice. Physical appearance: 1. White rice: It as the name says is white

Title: Hydrolysis of macromolecules Abstract: This lab was designed to teach the process of “hydrolysis”‚ a chemical reaction in which water is added to a polymer‚ breaking its bonds and forming smaller molecules. A hydrogen cation and a hydroxide anion (which once formed water) break apart and attach themselves to the ends of shorter polymers. Hydrolysis plays an important role in our lives and in the lives of every living thing on earth. Living organisms rely on digestion (hydrolysis)
