Biochemistry Enzymes
Action of enzymes as catalysts in biochemical processes

* Enzymes acts as catalyst and increase the rate of all the chemical reactions. * Enzymes are also described by two properties like all other catalysts. It composed of two main functions. * The first function is that, they increase the rate of chemical reactions by without consumed themselves or undergo any change or alteration in the reaction. . ( Zemitec et,al 2008). * The second function is, they increase reaction rates without changing the chemical equilibrium between the reactants and products. ( Bhagavan et,al 2006). * The reaction between two substrates are catalyzed by enzymes. The enzyme brings a template upon which the two substrates are combined together in the proper position and make them to react each other.
Deficiency in aldolase B and hereditary fructose intolerance * Hereditary fructose intolerance is a condition I which affects a humans ability to digest the fructose sugar. The incidence of hereditary fructose intolerance is 1to 2 in 20000 to 30000 individuals in a year worldwide. .( John .R.H 1996) * Hereditary fructose intolerance can be caused by mutations in the ALDOB gene. The ALDOB gene is responsible for making the aldolase B enzyme. The aldolase B enzyme is primarily seen in the Liver. This helps for the fructose metabolism. This enzyme is responsible for the further step in the metabolism of fructose, which breaks down the molecule fructose-1-phosphate into other molecules called glyceraldehyde and dihydroxyacetone phosphate. * The lack of aldolase B can results in the accumulation of fructose 1 phosphate in the liver. This seems to be toxic and can cause death of liver cells. The short of aldolase B can cause the reduction of dihydroxyacetone phosphate and this will lead to decrease in phosphate level in the body. ( Monique L 2008) * The damage of liver cells and a decrease level of phosphate groups will lead to hypoglycemia and will damage

    Aldolase B, can no longer take its substrate, F-1-P, and turn it into the products, DHAP and Glyceraldehyde. During HFI, fructose is still being phosphorylated by fructokinase, leading to a build up of F-1-P, and will no longer being used for glycolysis or gluconeogenesis. The continued use of phosphorous leads to the depletion of the free phosphate pool in the cells. The electron transport chain requires phosphate to make ATP. With the low amounts of free phosphate available, ATP production slows. Essentially, fructose is no longer being used as energy by the liver cells. Liver cells are now low on energy leading to liver damage and eventually liver failure. Fructose-1-phosphate produces the symptoms of HFI. It normally acts a signal in high blood sugar instructing the glucokinase to stay in the cytoplasm, so it does not go into the nucleus. When blood sugar is low, and F-1-P builds up, it signals the glucokinse to stay in the cytoplasm leading to a glycogenolysis and gluconeogenesis slowing down. When low blood sugar occurs, the liver cannot release glucose into the blood to help stabilize it, this is known as hypoglycemia. Many symptoms that are involved with hereditary fructose intolerance have to do with hypoglycemia, such as shakiness, headaches, and irritability, in addition to phosphate related liver issues (Sanders,…

    Enzymes do their work as catalyst by speeding up the process to improve performance. They lessen the activation energy making producing products easier .Enzymes act on specific substances in our bodies. The enzymes will fit into the substance or substrate like a lock and key .Once it is with its certain substrate, it acts like a key and it unlocks the substrate and the substrate can do what it needs to do and then the enzyme will releases from it and is not changed ,then it moves on to another substance.…

    The lack of available insulin results in a disorder in the metabolism of carbs, protein, and fat. Because they are attempting to rid the body of excess glucose, the kidneys excrete the glucose along with water and electrolytes (esp. sodium and potassium). The fatty acids are converted into ketone bodies by the liver. Ketone bodies are acidic; their accumulation in the circulation due to lack of insulin leads to metabolic acidosis.…

    In case study one; the patient is diagnosed with hereditary fructose intolerance with many symptoms including: loss of appetite, jaundice, kidney and liver not functioning, and generalized tremors. Hereditary fructose intolerance is when the person is lacking the enzyme that is needed to break down fructose. Enzymes are able to simplify chemical reactions, reduce energy requirements and achieve the desired results with incredible precision (http://www.sternenzym.de/english/enzymes/index.html). In enzymatic processes the risk of unintentional side reactions can be excluded almost entirely, since each enzyme fits only one substrate like a key in a lock: it only boosts the reaction to which it belongs (http://www.sternenzym.de/english/enzymes/index.html). The enzyme that is missing is called the aldolase B. When this enzyme is missing the body cannot break down fructose which then chemically alters the process of changing glycogen into glucose. Blood sugar may fail and then causes the liver to store substances that are dangerous to the body. Aldolase B is found in the liver but also in the kidneys and intestinal. Aldolase B is responsible for the second step in the metabolism of fructose, which breaks down the molecule fructose-1-phosphate into glyceraldehyde and…

    Congenital sucrose intolerance due to sucrose malabsorption was first reported in 1960 by Weijers et al. in three children, in one of whom maltose tolerance was also poor [27,77]. Five patients with sucrose intolerance described by Prader et al. in 1961 [22] were later shown to have an additional intolerance to isomaltose and palatinose [23-251 which are split by the same enzyme [26]. A total of thirty-four cases of congenital sucrose intolerance have increased absorption of intact…
