Summary of Carbohydrates: Monosaccharides‚ Disaccharides‚ Polysaccharides Carbohydrates are molecules that are synthesized from carbon‚ oxygen‚ and hydrogen atoms. Some types of carbohydrates consist of a single unit consisting of a few atoms‚ while other carbohydrates consists of thousands of units linked together through chemical bonds. Glucose‚ maltose‚ and glycogen are three carbohydrates that are similar‚ but structurally different. Carbohydrates have the general molecular formula CH2O. Starch

In the quest to combat pre-diabetes‚ a lifestyle disease that he was diagnosed with‚ Professor Tim Noakes embarked on and advocated for a Low Carbohydrate High Fat diet. The aim of the LCHF diet is to achieve a nutritional balance of 5% carbohydrates‚ 60-70% fats and 20-30% protein‚ and claims to control insulin levels resulting in weight loss‚ body weight control and prevent insulin resistance. The control of insulin levels and the hindrance of insulin resistance are of great importance since if

Carbohydrate Powders: During an intense weight training workout‚ the glycogen stored in the muscles and liver is the main energy source. Optimal strength and endurance during your workouts it is very important that these glycogen supplies are completely restored before starting a new workout. The best moment to replenish exhausted glycogen supplies is during the first 2 hours after the workout. Easily digestible food products containing lots of fast absorbing carbohydrates high glycemic index are

Comment 14: Page 8: Explain if pH was controlled during fermentation. In any case‚ do a reference in the result section to the pH at the end of fermentation Response: The pH was not directly controlled during the fermentation. In the line with typical studies conducted for ABE production‚ the medium was supplemented with buffer (50 g/L KH2PO4‚ 50 g/L K2HPO4‚ 220 g/L C2H3O2NH4) as an approach to control the pH changes during the fermentation. In addition‚ it has been reported that lignocellulosic

THE EFFECT OF INHIBITORS AND MANIPULATION IN ENERGY PRODUCTION OF YEAST CELLS FOR GLYCOLYSIS AND FERMENTATION INTRODUCTION The aim of this experiment was to study the process of alcoholic fermentation in Saccharomyces cerevisiae (yeast cells) and measure the rate of Co2 production during anaerobic breakdown of the respiratory substrate‚ sucrose‚ in the yeast cells. The effects of an inhibitor on respiratory enzyme were also looked at. It is hypothesized that the five different reaction mixtures

in biological systems. Glycolysis is the sequence of reactions that converts glucose to pyruvate with the concomitant formation of ATP. Three fates of this pyruvate produced exist. In this practical the production of pyruvate and acetaldehyde by fermentation of glucose is established. A series of test tubes was set up each containing glucose and yeast suspension in buffers at different pH values. These test tubes were incubated for an hour at 37℃. Trichloro-acetic acid solution was then added to the

Abstract Carbohydrates are important in metabolic processes for everyday physical and chemical actions. The carbohydrate‚ glucose‚ is a key component in generating adenosine triphosphate‚ also known as ATP. In order to analyze unknown glucose levels‚ a DNS assay was performed. By using 2-hydroxy-3‚5-dinitrobenzoic acid to oxidize the aldehyde group on the carbohydrate‚ the reducing end of glucose increases in absorbance of 540 nm. Using a UV spectrophotometer‚ the concentration was calculated

Carbohydrates come in a variety of sizes. Describe the basic chemical structure of carbohydrates and explain how larger ones are made. How do the category names of different carbohydrates relate to the complexity? Finally‚ what are they used for in organisms? Carbohydrates are made by the basic chemical structure of Carbon‚ Hydrogen‚ and Oxygen‚ in the same two to one ratio that makes up water. It is made bigger when an enzyme comes in and takes hydrogen and oxygen away from two different
