electrochemical oxidation of the lysergic acid type of ergot alkaloids‚ the mechanism may be generally applicable for compounds having the ergoloid skeleton. In the course of the work it was concluded that a simple DC amperometric method of detection in a FIA system could be applied to determine the content of ergot alkaloids of different pharmaceutical preparations. A suitable method designed to meet current analytical requirements has been developed and validated. Keywords: Electrochemical oxidation; ergot

photosynthetic prokaryotes use the energy from sunlight to convert carbon dioxide and water to glucose and oxygen (a waste product). The summary reaction for photosynthesis can be written as 6 CO2 6 H2O C6H12O6 6 O2 This type of reaction is an oxidation-reduction (or redox) reaction. This reaction is also [anabolic/catabolic] and [endergonic/exergonic]. In redox reactions‚ electrons (and associated H ions) are transferred from one compound or element to another. If one compound or element

in the first place. They also prevent heavy metals from sparking oxidation. Prevention is vital‚ since oxidation causes the body to break down and become weak. The second is it intercepts oxidizing radicals that have already formed and stop them from multiplying. Unless the body has ample defenses‚ oxidizing chain reactions will make it vulnerable to further damage. The third is it gets to work on damage already caused by oxidation. The body has an amazing ability to heal‚ and with this defense system

appearance etc. Lipid oxidation is an important deteriorative reaction‚ which has significant implications in terms of the quality and value of fats and oils‚ specifically in relation to the off-flavours that develop as a result of autoxidation. Rancidity is caused by hydrolysis and oxidation. Heat‚ moisture and exposure to light will increase these chemical reactions and thus increase the likelihood of the onset of rancidity.During the initial stages of the oxidation process‚ hydroperoxides accumulate

reactions of the tricarboxylic acid cycle. Krebs determined how to accelerate the rate of oxygen consumption and pyruvate oxidation by adding specific dicarboxylic and tricarboxylic acids that stimulated the oxiation of pyruvate. Malonate‚ a succinate dehydrogenase inhibitor caused all intermediates to lose their effect on pyrucate oxidation. He determined that the oxidation of pyruvate was accomplished through a cyclic pathway and that pyruvate perforated the pathway by combining with oxaloacetate
