plant that resist digestive enzymes. A few definitions of dietary fibers are nondigestible carbohydrates and lignin that are intrinsic and intact in plants. nondigestible carbohydrates and lignin that are intact in plants. Another definition is the edible parts of plants or analogous carbohydrates that are resistant to digestion and absorption in the human small intestine‚ with complete or partial fermentation in the large intestine. Dietary Fiber are not necessary for our body‚ but they do help us

The first procedure that was done was the gram stain. Under a microscope‚ if the gram stain is purple‚ the bacterium is gram positive‚ if the stain is red‚ it is gram negative. The next test was the fermentation tests for glucose‚ sucrose and lactose. If an organism is able to ferment the carbohydrate‚ there will be acid produced‚ which will turn the broth yellow. Homofermentation shows that only one product was produced-acid. Other organisms will carry out heterofermentation‚ the presence of acid

milk is important when examining the quality of milk because it indicates the total amount of nutritive value of milk when water is removed (Leila et al‚ 2014). Milk is made up of about 87% of water and 13% of other components such fats‚ protein‚ carbohydrate etc. (Ward et al‚ 2016). Sheep milk is highly nutritious‚ rich in vitamins A‚ B‚ and E‚ calcium‚ phosphorus‚ potassium‚ and magnesium (Caja and Francois‚ 2017). It contains a higher proportion of short- and medium-chain fatty acids‚ which have

Living organisms catabolize organic molecules within their cells and use the energy released to manufacture ATP by phosphorylating ADP. Many prokaryotes and virtually all Eukaryotes phosphorylate ADP either through fermentation (anaerobic) or respiration (aerobic). Both of these processes involve oxidation of foodstuffs‚ yet only the latter requires oxygen. Cellular respiration is a very complex process that consists of many steps that take place inside the cell‚ in an organelle called a mitochondrion

BIOFERTILIZER: The pathophysiology of the Tuberculin reaction is explained thus: M. Tuberculi are engulfed by macrophages after being identified as foreign‚ but due to a self- preserving mechanism peculiar to TB it is able to block the fusion of the phagosome within which it is existing with the lysosome which would destroy it. So it can continue existing and replicating within the immune cell designed to destroy it. After several weeks‚ the immune system somehow [ mechanism as yet unexplained]

LACTOSE – C12H22O11 Chemical and Biochemical Properties Lactose is very stable and inert from a chemical point of view. It has no significant tendency to react with the drug or other components of a formulation. Some remarks on the chemical properties of lactose are useful however‚ the low hygroscopicity of crystalline lactose supports its virtual chemical inertness. Most chemical reactions of lactose occur noticeably only in aqueous environment. Because lactose has a very low tendency to attract
