PRODUCTION OF CITRIC ACID Introduction: Citric acid is a White solid‚C3H4OH(COOH)3‚soluble in water and slightly soluble in organic solvents‚ which melts at 153 oC. Aqueous solutions of citric acid are slightly more acidic than solutions of acetic acid. Traces of citric acid are found in numerous plants and animals‚ because it is a nearly universal intermediate product of metabolism. Large amount of the acid are found in the juice of citrus fruits‚ from which it is precipitated by the

Introducton : The most common macromolecules found in living organisms are carbohydrates ‚ lipids‚ proteins and nucleic acids. Briefly‚ the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy‚ information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests‚ many cannot. Scientists then use certain tests to determine the presence of

The Effects of Acid Rain on Plant Growth PURPOSE The purpose of this experiment was to determine to what degree acid rain affects the growth of certain plants. I became interested in this idea because I’m worried about our environmental conditions and it sounded very interesting to me. The information gained from this experiment may be used to as a warning to stop air pollution. HYPOTHESIS My hypothesis is that the plant watered with the acid solution will grow more slowly than plant’s

Insulin Synthesis The discovery of insulin was one of the greatest events in medical history. The existence of insulin is as necessary as that of glucose (the body’s basic unit of fuel). Both of them are related and required for life. In order for the glucose to be regulated‚ insulin circulates through blood vessels and bind with particular (insulin) receptors‚ promoting interactions essential for the wellbeing of the body’s internal mechanisms. Insulin is a hormone synthesized exclusively

Secondary excitotoxicity is thought to be more relevant to chronic neurodegenerative disorders than the classical acute form. In this pathway increased glutamate levels are not required as disturbances with the neuronal resting membrane potential cause glutamate receptors to be over-activated by physiological levels of glutamate. In a neuron which is affected by another pathological process and shows reduced ATP production‚ Na+ dysfunction or impaired glucose metabolism and as a result has an abnormal

OIL PURIFICATION A SCIENCE INVESTIGATORY PROJECT CHAPTER I Background of the Study INTRODUCTION Oil used in cooking foods is commonly derived from vegetables. Cooking oil is commonly used for frying and oil used for frying is usually thrown away. The recycling of cooking oil also provides a form of revenue for restaurants‚ which are sometimes compensated by cooking oil recyclers for their used deep fryer oil. Cooking oil recycling also results in less used oil being disposed

I. I haven’t heard of FFP during the first semester actually. I just knew that the following semester I would be needing a white book with a flame print on it. I really didn’t care about the subject so much even though I was already attending the classes. To tell you the truth‚ I thought that FFP would be the simplest subject in my load but as it turns out‚ it proved to be quite stressful. Not bad stressful but good stressful‚ okay‚ maybe sometimes bad stressful. I learned a lot of values from this
