if treatment is delayed‚ the damage to the brain is irreversible (Sharon Rady Rofles & Kathryn Pinna & Ellie Whitney‚ 2009). Galactosaemia is treated through dietary restrictions. People with the disorder must avoid foods and beverages containing lactose‚ which is made up of galactose and glucose. The main focus of dietary treatment is the exclusion of milk and milk products. Other examples include organ meats and legumes (Genetic Science Learning Center‚ 2012). With continued dietary management‚

differential and selective medium used to select for gram-negative bacteria. It also differentiates lactose-fermenting bacteria from non-lactose-fermenting bacteria. Only #1 was used to inoculate this medium. After inoculation‚ the plate was incubated at 37◦C for 18-24 hours. Observation shows there is a bright red growth but no change in the appearance of the medium. This indicates no lactose fermentation‚ however since there is growth‚ this means the bacterium in gram-negative. Mannitol

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 negatively and therefore are considered non-reducing sugars. Table

Although the sale of raw milk is prohibited in Canada‚ some people nevertheless believe in the virtues of this product‚ claiming that pasteurization destroys important vitamins and that drinking raw milk can prevent or treat allergies‚ cancer or lactose intolerance. But is this really true? To find out‚ researchers in Ontario reviewed and analyzed 40 studies on the effects of pasteurization and the nutritional value of milk. The first finding: pasteurization has a small effect on the vitamins naturally

ntroduction The purpose of this experiment was to use Iodine‚ Benedict and Biuret to test the reaction of the following 12 samples: 1% glucose‚ 0.3% glucose-1-phosphate‚ 1% maltose‚ honey‚ 1% sucrose‚ 1%lactose‚ 1% glycogen‚ 1% starch‚ protein‚ beer‚ distilled water and an unknown solution (test tube: 300). The iodine test for starch was to test how would starch reacted if we put iodine in it. The color of starch before the test was clear. The color of the iodine was brown. When you added iodine
