Calcium Oscillations: Synthesis and Binding Studies of Photo-reversible Calcium Chelator Harpreet Sandhanwalia December 2‚ 2011 Dr. Alison McCurdy Abstract: Living bodies maintain a homeostasis by constant communication amongst the various cells and organs. Calcium plays a very important role in controlling this network of communication and henceforth helping in carrying out many essentials functions. However the exact working of Calcium

amount of calcium ions. If time permits‚ I could perhaps investigate other variables such as pH‚ surface area and concentration and their effect on calcium leaching. Moreover‚ I could also use other types of fish soup stocks and compare to determine which soup has more calcium in it. Lastly‚ I have purchased “cleaned” anchovies from the supermarket to carry out this experiment‚ where the head and bones are removed as opposed to using whole anchovies found at hawker stall.

Hypercalcemia is the term used when the blood calcium levels are higher than normal. Calcium is an important mineral for the body. Ninety-nine percent of the calcium is stored in the bones and about one percent circulates in the blood. Calcium is crucial for bone formation and also for the brain‚ the nerves‚ and the muscles to function properly. When calcium levels are too high or too low it causes problems in many parts of the body. The causes‚ symptoms‚ diagnosis‚ treatment‚ and prevention of

Introduction The experiment is testing for the formation of precipitates caused by different limiting reactants. A precipitate results in a solid formed by an ionic compound. Calcium nitrate and copper sulfate will be added to separate beakers with approximately half of the solutions from the Büchner funnel system of each trial to test for the formation of precipitates. The limiting reactant is the reactant that will run out first in the chemical reaction. It is important to recognize which chemical

If you do not wash all of the Calcium Carbonate out‚ then the percent yield would be smaller because there is enough calcium carbonate left in the beaker that would have attributed to the final yield. b. If you used tap water instead of DI water what do you think would happen? Why? If you used tap water‚ the coffee filter would have weighed more after the calcium carbonate

not drink human milk‚ but drink the milk of other species‚ and do so commonly throughout their adult lives. Milk is not only drank but is often used in cooking. New alternatives to milk‚ such as calcium-enriched juices‚ soymilk‚ and rice milks‚ have stormed the markets. In Asian markets‚ powdered calcium is a popular commodity‚ often spooned into a pot of rice or soup. We have been told milk "does a body good" and is important for growth in children and maintaining health in adults. But some scientific

how the presence of Ca++ ions in the extracellular and intracellular environment affects the secretion of trichocysts. Our first our hypothesis tested whether extracellular calcium is required for the secretion of trichocysts by treating cells with EGTA‚ an agent that blocks calcium ions; our second tested whether increased calcium will counter the inhibitory effects of EGTA; our third tested whether adding different ion‚ like MgCl‚
