transformation of ketoses to aldoses‚ resulting in all monosaccharides and most disaccharides reducing the blue Cu2+ ion to cuprous oxide (Cu2O)‚ a brick red-orange precipitate. Examples of reducing sugar are glucose. Examples of non-reducing sugar are sucrose. Monosaccharide‚ which is smallest carbohydrates molecules‚ can be described by the number of carbons in the chain so that a monosaccharide with five carbons in a chain is a pentose and one with six carbons is a hexose. A monsaccharide contains one

INTRODUCTION Macromolecules are highly important organized organic molecules that are found within living cells. These biological molecules help the body execute precise important tasks. There are four types of macromolecules: carbohydrates‚ lipids‚ proteins and nucleic acids. (Karp‚ 2010) This specific experiment showcased the identification of different macromolecules using three different testing methods. Carbohydrates‚ sugar molecules‚ are known as “fast fuel” in the body‚ and they contain

Sugar is sucrose that is extracted from sugar beets and sugarcane. Sucrose‚ or table sugar‚ is the most common added sugar‚ and is found in the form of high fructose corn syrup. Americans consume up to 60 pounds of sugar in one year‚ that is 76.7 grams of sugar per day‚ which equals 19 teaspoons or 306 calories! This number is much larger for people that eat more processed foods or drink soda beverages on a regular basis. No sugar is healthy‚ but an average amount of sugar for men‚ should be around

diseases. But before we can truly testify anything we have to truly understand we have to break it down into its two ingredients that it is made up of‚ glucose and fructose. Sugar‚ or its natural form‚ sucrose‚ is a carbohydrate‚ which makes it an energy substance. It is also known‚ as sucrose is a sweet crystalline substance obtained from various plants‚ especially sugar cane and sugar beef. It is used a sweetener in foods to make them taste better‚ and is made up off glucose and fructose.

Introducton : The most common macromolecules found in living organisms are carbohydrates ‚ lipids‚ proteins and nucleic acids. Briefly‚ the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy‚ information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests‚ many cannot. Scientists then use certain tests to determine the presence of

Gatorade Reigns Supreme Over Powerade Gatorade and Powerade two similar sports drinks on the surface‚ but what lurks in the shadows is what separates these two drinks. On the surface Gatorade and Powerade look the same and may not taste that much different to some people. However their ingredients is what separates them from one another. One is a lot better than the other‚ and it’s Gatorade. Gatorade is a much better sports drink than Powerade because it has more sodium‚ the sugar they use has less

word Fermentation has been derived from Latin (Ferver which means to ‘boil’).As during fermentation there is lot of frothing of the liquid due to the evolution of carbon dioxide‚ it gives the appearance as if it is boiling. Sugars like glucose and sucrose when fermented in the presence of yeast cells are converted to ethyl alcohol. During fermentation of starch‚ starch is first hydrolysed to maltose by the action of enzyme diastase. The enzyme diastase is obtained from germinated barley seeds. Fermentation

negatively affected or positively affected due to the concentration balance in their environment. Potato cells were used to see the affects of sucrose in different concentrations. In some concentrations a weight change was seen in the potato. Introduction In the osmotic concentration lab potatoes were used to see the affects of different concentrations of sucrose on the weight of the potatoes. Solanum tubersummore commonly known as the potato is the fourth most important food crop in the world. It
