Theoretical Background Coffee has being blamed for so many ills from causing diseases and cancers to many people. Recent study states that coffee intake is not bad at all and doesn’t find any health benefits in causing cancer and diseases. However these studies state that a mild intake of unfiltered coffee can increase cholesterol levels. Newer studies have also shown that coffee may have benefits‚ such as protecting against Parkinson’s disease‚ type 2 diabetes and liver cancer also it has high

Introduction Although bacteria is microscopic in size‚ it is largely important in the healthcare field‚ environmental work‚ food preparation‚ as well as many other industries. In particular‚ it is essential that healthcare workers be able to identify the species of bacteria invading a human reservoir in order to prescribe the correct antibiotic that will kill that species. For the purpose of bacteria identification‚ numerous tests have been devised to find out the exact species in question. However

quantitative analysis in various fields such as biology‚ chemistry. -ONPG is a compound structurally similar to lactose and thus is used as a substrate instead of lactose. Lactose Galactose + Glucose‚ however these products are not easily quantifiable. By substituting glucose with a compound that can be easily noticed with a distinguishable colour change‚ we can then assay for lactose activity. ONPG is colourless but gives Galactose and a yellow coloured compound‚ 0-Nitrophenol (ONP) Galactose-ONP

reabsorption in the kidney‚ or muscle contraction. There are two other monosaccharides: fructose and lactose. Fructose is found in sperm and in fruits‚ to make them more attractive to animals. Lactose is found in the milk of mammals and is an important energy supply for their young. These monosaccharides also help to build disaccharides. Glucose and fructose join together to form sucrose and glucose and lactose join to form galactose. Sucrose is the major transport carbohydrate of green plants. It is transported

Let’s start. • Nutrition is a study of the interactions occurring between you & food. • Nutrients – about 45 substances that provide energy‚ structure or regulation of body processes. • Essential nutrients- need them‚ but can’t make them or fast enough. • Macronutrients- need in large amounts (carbohydrates‚ fats/lipids‚ proteins – provide energy/calories) • Micronutrients – need in very small amounts (vitamins‚ minerals- no energy/calories) • Phytochemicals- another category in plant food-

to the family Enterobacteriaceae. The historical definition of this group has been based on the method used for detection (lactose fermentation) rather than on the tenets of systematic bacteriology. Accordingly‚ when the fermentation technique is used‚ this group is defined as all facultative anaerobic‚ gram-negative‚ non-spore-forming‚ rod-shaped bacteria that ferment lactose with gas and acid formation within 48 h at 35°C. The standard test for the coliform group may be carried out either by the
