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

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

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

involves the nucleophilic addition of an organomagenesium complex to a carbonyl carbon followed by acid work-up. This reaction involves a single electron transfer between the carbonyl group and the grignard reagent. Once the Grignard reagent is synthesized it can work as a base by abstracting a proton or it can work as a good nucleophile. When it works as a base it can be added to water‚ alcohols‚ amines‚ acids‚ terminal alkynes and etc. When it works as a nucleophile‚ its nucleophilicity reacts with the
