THE PROCESS OF FERMENTATION THROUGH DIFFERENT KINDS OF SUGARS In order to produce ethyl alcohol fermentation‚ we had to determine what sugars used‚ such as glucose (a single sugar) sucrose (table sugar) and lactose (milk sugar) will react with yeast to produce ethyl alcohol fermentation. My hypothesis is that the sugar lactose would produce the highest amount of bubbles and ferment. INTRODUCTION: The significance of fermentation is a lengthy process that has been practiced by humankind

Abstract Much of our money is spent eating out. Our food is processed‚ refined‚ concentrated‚ sugared‚ salted and chemically engineered to produce high-calorie‚ low-nutrient taste sensations. This problem is unique to westernized peoples. Rural populations in China‚ Japan‚ and Southeast Asia who have little access to rich foods experience few heart attacks. Similarly‚ most people in rural Africa and South and Central America have little fear of diabetes and cardiovascular disease. Yet in North America

disulphide bond. It is produced by the beta cells in pancreatic islets to maintain the blood glucose at optimum level. When there is a rise of glucose in the blood especially after meals‚ insulin works to convert glucose into glycogen by glycogenesis as well as into lipid by lipogenesis. However‚ in people with type 1 diabetes‚ their body are not able to supply sufficient insulin for converting the glucose into glycogen as the storage

oxygen‚ while proteins (composed of amino acids) have amino groups (-NH3+) and carboxyl (-COOH) groups. These characteristic subunits and chemical groups impart different properties to the macromolecules. For example‚ monosaccharides such as glucose are polar and soluble in water‚ whereas lipids are nonpolar and insoluble in water.

The aim of our investigation is to find out whether the use of different sugar isomers with yeast‚ will affect the rate at which the yeast respires at. The sugars to be tested are fructose‚ galactose‚ glucose‚ lactose and sucrose. Their effects on the respiration rate of yeast to be observed through the measurement (cm3) of the displaced water‚ which will tell us how much CO2 has been respired over 2 minutes. To compare the effects an average will be calculated for each and a result will be drawn

experiment used six smith fermentation tubes‚ distilled water and sugar substrates. It composed of six set-ups which used 15ml of 10% yeast suspension‚ 15 ml distilled water and 15 ml of their assigned sugar substrate namely: starch‚ lactose‚ sucrose glucose and fructose respectively. Set-up six was the controlled set-up and did not contain any sugar substrate. The opening of the tube was covered with a cotton ball to prevent oxygen from entering. The set-ups were then observed every five minutes for

Complex Carbohydrates PERSONAL SUMARY: There is a very real difference between simple and complex carbohydrates. Let’s look at them. Simple carbohydrates‚ found in rice‚ pasta‚ white potatoes‚ and some dairy products‚ contain sugars that are broken down quickly by your body. This will provide your body with a quick burst of energy‚ but if the carbohydrates are not used quickly‚ the sugar will turn to fat. That’s why low-carb diets cut them out. But those diets often lump all carbs together
