The Role of Fat and it's importance in our diet !1 LIPIDS • Lipids are non soluble molecules that include fats, waxes, sterols, & phospholipids. Lipids main function is storing energy, sending chemical messages in cells, and are components in cell membranes. Lipids make up adipose tissue which is a connective tissue that is made up of lipid cells called adipocytes. Lipids can also be metabolized leading to a large amount of ATP (energy in the body) production. When Lipids are broken down they are broken into a glycerol molecule and fatty acids.
It is important for an IV solution to have salts in it so the water and solute can be equal to create an isotonic environment. If there wasn’t, there would either be a hypotonic causing the cell to burst, or there would be hypertonic causing the cell to shrink. We created models of living cells by using dialysis tubing. The dialysis tube represented the cell membrane to act as selectively permeable to water and some solutes. We observed different solutes (NaCl, Ovalbumin, Glucose, Sucrose, and Water) in the dialysis tubing.
It is affected by various factor like secretion from glands, content and amount of secretion etc., affect the drug transport through this route. This route consist only 0.1% of total skin surface. ii) Transcellular route :- Drug transport through this route passes from corneocytes which has highly hydrated keratin making hydrophilic pathway. This corneocytes are surrounded by lipid connecting these cells. So a drug requires a number of partitioning and diffusion step.
Angela Johnson GE150 08/03/2014 Unit 7 Lipids versus Carbohydrates Your body stores energy in the form of triglycerides, each triglyceride contain three fatty acid compounds bound to glycerol chemical backbone. Most triglycerides are stored in adipose tissue made up of fat cells distributed throughout your body. Carbohydrates are stored as glycogen a large number of carbohydrate molecules are made up hundreds or thousands of smaller units of glucose, a simple sugar. Your body can also convert carbohydrates into fat for long term energy storage. Carbohydrate is the universal energy cell.
Most differential stains have a challenge step that follows staining with a primary dye. In the Gram stain the challenge step is a rinse with either ethanol or acetone (either may be used). This step dehydrates and tightens the cell wall of Gram positives (mainly peptidoglycan) such that the rinse does not enter the cell. Gram negatives have mainly a lipid cell wall (even though they do contain peptidoglycan) that allows the challenge rinse to penetrate the cell and rinse out the crystal violet-iodine complex rendering the Gram negative cell colourless. Thus, the Gram negative cells must be stained to be seen, and this is done with the counter stain.
KSCN ionizes into K+ and SCN-, and in the presence of the H+ ion supplied by nitric acid, the H+ and SCN- will combine to form the weak acid HSCN. Since there is a large excess of nitric acid compared to KSCN, we can assume that all of the SCN- will be in the form of HSCN. Procedure part 2: Six test tubes were filled with various amounts of 0.003M sodium thiocynate. A constant amount of 10 ml of 0.003 M Fe(NO3)3. The first tube had no sodium thiocynate.
A diuretic provides the means of forced diuresis, which increases the rate of urination. There are many categories of diuretics, but all of them increase the excretion of water from bodies. One of the most important functions of diuretics is that they remove all of the excess water from the body. Caffeine contains Xanthines, which is a diuretic through inhibiting the reabsorption sodium ions, and increasing the glomerulus filtration rate. Water filters from the blood through the kidneys.
[ (Unknown, Salt, essential nutrient, 2011) ] For this report salt reference will be as: A colorless or white crystalline solid, chiefly sodium chloride, used extensively in ground or granulated form as a food seasoning and preservative. African Americans have some the highest rates of blood pressure in the world. (Max C. Reif, 2011) Blood pressure: is the driving force of circulation for oxygen rich blood. Pressure exerted by blood: is the pressure exerted by the blood against the walls of blood vessels. Pressure can be high: Hypertension; or low: Hypotension.
When CO2 is higher, pH is lower or acidic. When pH is acidic, hemoglobin is released to tissues that need oxygen. The relationship between oxygen affinity and pH Compare the biochemical structure of hemoglobin to myoglobin The molecular difference between normal and sickle forms of hemoglobin The difference between normal and sickle red blood cells at the cellular level How the diseased cells are different from normal red blood cells in their capacity to carry oxygen A normal RBC is round and concave shaped that easily moves through the bloodstream. A sickle hemoglobin releasing oxygen sticks together, forms fiber formations that causes the sickle appearance. This decreases the capacity to carry oxygen and also by not moving through smaller circulation easily causes blockages.
