From Celiac Disease to general distaste‚ gluten-free diets are on the rise and it may seem to some that the appearance and prevalence of gluten-sensitivity is a modern phenomenon‚ cashing in on a Western trend without a real scientific base. It may surprise the cautious reader to discover that Celiac Disease is in fact one of the most common long-term diseases worldwide with a history likely dating back to at least the first and second centuries. This begs the question: what is celiac disease? Where

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

ABSTRACT In todays world of ever evolving genetic mutations the incidence of drug resistant forms of microorganisms are on the rise. The importance of identifying these pathogens and their related epidemiology has become increasingly more important. The purpose of this study was to identify an unknown bacterium in a controlled laboratory environment over a 5 week period. Utilizing a variety of differential testing and staining methods learned in the microbiology course‚ students were to determine

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

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

Introduction Water is necessary to life but it can be unhealthy too. In general‚ the water quality is poor in developing countries like Kenya. Water is a vector of diseases like yellow fever‚ diarrhea… Water purification is very important in these countries but people don’t have a lot of time to spare‚ they work or they are in the field and in general women must spend a significant amount of time walking to collect water. So we need to find a quick‚ easy‚ and economic solution that is as simple
