10/27/15 Vitamin D Deficiency Regarding Muscles Vitamin D deficiency has been tied to mainly bone pathologies. Recent research shows that the effects of Vitamin D span further than just affecting bones and particularly cause muscle weakness. Vitamin D is responsible for aiding in the absorption of other minerals‚ such as calcium. Calcium is a key ligand in muscle contractions‚ thus‚ Vitamin D indirectly can effect muscle contractions.

October 14‚ 2011 Vitamin B12 Deficiency Vitamin B12 deficiency is also known as Cabalamin‚ it is a water-soluble vitamin that helps to maintain the healthy central nervous system and the formation of the red blood cells. Usually water soluble vitamins can’t be stored by the body. However‚ Vitamin B12 is a special kind of vitamin that can be stored in the liver for years. It is also needed to make the DNA material that exists in every cell. The average adult needs 2.4 microgram of vitamin B12 daily. Pregnant

Determination of KHP – Acid - Base Titration For determining purity of unknown KHP‚ acid – base titration was used. Molarity of titrant in this case NaOH was standardized as 0.04958(±0.00011) M. Purity of unknown KHP was calculated as 35.88(±0.16) %. • Introduction Acid – base titration is typical method of determining unknown figures. Acid – base titration means that by using neutralization between acid and base. Abrupt changing of pH says whether procedure is done or not. pH indicators

Neutralization experiment AIM:- To investigate how heat is given out in neutralizing sodium hydroxide (NaOH) using different concentrations of Hydrochloric Acid. Background Information:- Substances that neutralize acids are called alkalis. An acid is a substance that forms hydrogen ions (H+ ) when placed in water. It can also be described as a proton donor as it provides H+ ions. An example of an acid is hydrochloric acid (HCl)‚ Sulphuric acid (H2SO4) etc. An alkali is a

then subsequently titrated with thiosulfate solution‚”2 being the difference from the former type of iodine titration. Iodometry is more widely used‚ as in this experiment‚ because there are only a few strong reducing agents; thus few iodometric determinations. (2) As mentioned earlier‚ iodometry involves the oxidation of iodide ion; it is added in excess to the oxidizing agent being determined. This would result to the formation of iodine which would be titrated with the standard thiosulfate solution

Plan a procedure that will allow you to compare quantitavely the glucose concentration in fresh samples of orange‚ lemon and grapefruit juice. Aim: The aim of this investigation is to produce a set of data which will enable comparison of the glucose concentrations of orange‚ lemon and grapefruit juice. Research: Benedict’s Reagent is a mixture of sodium compounds and copper sulphate. The copper ions are reduced by fructose (a reducing sugar) to form copper oxide‚ thus turning it from blue

Vitamin D is a fat-soluble vitamin that can be found in food but significant amounts of vitamin D can also be produced by the body. It can be obtained from sun exposure‚ food‚ and supplements are biologically inert and must undergo two hydroxylations in the body for activation. The two major forms of which are vitamins D2 (ergocalciferol) and vitamin D3 (cholecalciferol). This paper not only looks into the essential function of vitamin D on the subject of bone health‚ but also other non-calcemic

THE EFFECT OF CONCENTRATION ON REACTION RATE INTRODUCTION • Concentration is one factor which has an effect o the rate of a chemical reaction. In chemistry we describe concentration in terms of the number of moles of a substance there are in every cubic decimetre (litre) of solution‚ written as moles.dm-3 of M for short. • In this experiment you will find out how increasing the concentration of the acid solution changes the rate of the reaction between dilute hydrochloric acid and magnesium
