QUALITATIVE TESTS OF CARBOHYDRATES Final Lab Report Submitted by Brittany Fitzgerald 545301 Prepared for Nancy Cook Chemistry 3501 Monday November 26‚ 2012 RESULTS PART A: As a result of the Benedict’s test on various sugar solutions‚ it was found that galactose‚ mannose‚ arabinose‚ ribose‚ lactose‚ fructose‚ maltose‚ and cellobiose tested positively and therefore are considered reducing sugars. Glucose‚ starch‚ sucrose‚ and methyl-D-glucopyranoside on the other hand tested

essential carbohydrates needed for athletes‚ and the effects of consuming carbohydrates before and during competition is very important in helping with the enhancing of an athlete’s endurance and his or her exercise performance. It is critical for athletes to ingest a significant amount of carbohydrates in their bodies in order to compete at high performance levels. Carbohydrates are the main fuel source for our body‚ but as athletes we must know the difference between good and bad carbohydrates. Good

Carbohydrate and Diabetes Research NUR 115 AM The articles that I researched for this project were interesting and shed light on the relationship between carbohydrates and diabetes. Some of the information that I learned will be useful in my nursing career. Carbohydrates fill numerous roles in living things‚ such as the storage and transport of energy in the form of starch and glycogen etc. The basic carbohydrate units are called monosaccharides‚ such as glucose‚ galactose‚ and

substitutes; fats; free foods; combination foods; fast foods; and alcohol. Carbohydrate Counting When you eat a healthy meal or snack‚ it is usually a mixture of carbohydrate‚ pro- tein‚ and fat. However‚ your body changes carbohydrate into glucose faster than it changes protein and fat into glucose. It is the carbohydrate that makes your blood glucose level go up. In carbohydrate counting‚ you count foods that are mostly carbohydrate. These include starches (breads‚ cereals‚ pasta)‚ fruits and fruit

The amount of carbohydrates I consumed was more than double the RDA‚ Recommended Dietary Allowance. To help reduce my carbohydrate consumption‚ I plan on eating less cereal because that has become a go-to meal for me at college. Cereal can add up in sugar and carbohydrates quickly when it is eaten as a meal or in large amounts. I also plan to eliminate the amount of bread I
