1.0 Introduction This assignment is based on a study of alcohol metabolism and its impacts to human health. The assignment explains that how the body can dispose of alcohol and discern some of the factors that influence this process and influences of the process to the metabolism of food‚ hormones‚ and medications. 1.1 History of alcohol The word “alcohol” appears in English as a term for a very fine powder in the 16th century. It was borrowed from French‚ which took it from medical Latin.

acetyl CoA is able to enter the citric acid cycle because this is the most acceptable fuel input into the cell. The path that the pyruvate takes depends on the energy needs of the cell and the oxygen availability (Tymoczko‚ p. 318). Pyruvate dehydrogenase complex consist of three distinct enzymes each with its own active

In fat synthesis‚ the enzyme pyruvate dehydrogenase‚ which forms acetyl-coA‚ and also acetyl CoA carboxylase which forms malonyl-coA are obvious control points. These are activated by insulin. This leads to an overall increase in the levels of malonyl-coenzyme A‚ which is the substrate required for fat synthesis. Thus‚ the flux down storage pathway is increased when there is sufficient glucose in the ’fed’ state. Pyruvate dehydrogenase dephosphorylation Pyruvate dehyrdrogenase

Introduction All tissues have some capability for synthesis of the non-essential amino acids‚ amino acid remodeling‚ and conversion of non-amino acid carbon skeletons into amino acids and other derivatives that contain nitrogen. However‚ the liver is the major site of nitrogen metabolism in the body. In times of dietary surplus‚ the potentially toxic nitrogen of amino acids is eliminated via transaminations‚ deamination‚ and urea formation; the carbon skeletons are generally conserved as carbohydrate

males’ bodies have lower possibility to produce alcohol dehydrogenase. If drink same amount of alcohol‚ older males are more intoxicated than younger men. Menopausal women hormone changes obviously‚ which lead women to tend to more intoxicated than younger women at same amount of alcohol. People with liver damage also tend to more intoxicated because of their liver do not work as good as normal livers‚ they tend to produce less alcohol dehydrogenase. However‚ the frequent heavy drinkers tend to less intoxicated

he Krebs Cycle also expressed as: CH3C(=O)C(=O)O− (pyruvate) + HSCoA + NAD+ → CH3C(=O)SCoA (acetyl-CoA) + NADH + CO2 is the main pathway in all aerobic organisms. Basically it’s the way that cells produce energy for itself‚ but the only issue is it requires the presence of oxygen. In total eight reactions that take place in the mitochondria‚ and these reactions result in two carbon molecules and oxidizes it into carbon dioxide. Step 1 Citrate synthase bridges to Oxaloacetate substrates which can

Experiment 14. Dehydrogenase in yeast During respiration‚ hydrogen atoms are removed from glucose molecules by enzymes called dehydrogenases and passed to various chemicals called hydrogen acceptors. As the hydrogen atoms pass from one hydrogen acceptor to another‚ energy is made available for chemical reactions in the cell. In this way‚ substances such as glucose provide energy for vital reactions in living organisms. In this experiment‚ a dye called methylene blue acts as an artificial hydrogen

PREG is either converted to 17α-hydroxypregnenolone (OH PREG) by the 17α-hydroxylase activity of CYP17A1 or converted to progesterone (PROG) by the enzyme 3β-hydroxysteroid dehydrogenase (3β-HSD). PROG is further converted to 17α-hydroxyprogesterone (OH PROG) by the 17α-hydroxylase activity of CYP17A1‚ and OH PROG is also formed from OH PREG by 3β-HSD .
