Case 1: Hereditary fructose intolerance Enzymes are proteins that increase the rate of chemical activity. Their three dimensional structure determines their function‚ and is made of chains of amino acids that have folded into a specific shape with a unique property. Enzymes lower the activation energy needed for a chemical reaction‚ therefore speeding up the process. Multiple enzymes work together in metabolic pathways‚ taking a product (end result) of one metabolic reaction as a substrate (substance

Enzyme Report Case 1 - Hereditary Fructose Intolerance 1 & 2. Enzymes take on a variety of roles in the human body at the cellular level. Specifically‚ they aid in the breakdown of macronutrients such as glucose and fructose so that the body can use them. Although reactions within the body would occur without enzymes‚ enzymes provide control because the reaction is not needed all of the time. Enzymes function in specific environments such as temperature or pH; some enzymes are specific

(Wolfe‚ 2000) Importance of Aldolase B Enzyme -Glucose and fructose are the components that make up sugar (sucrose). -In order to make ATP (energy)‚ glucose and fructose need to go through glycolysis and enter the Krebs cycle. -Fructose needs enzymes to break it down further‚ before it can enter the glycolysis process. -Initially‚ fructose is broken down by the enzyme fructokinase into fructose-1-phosphate. -The substrate fructose-1-phosphate (F-1-P) is then further broken down by an enzyme

and then the enzyme will releases from it and is not changed ‚then it moves on to another substance. Heredity Fructose Intolerance is a condition that can be passed down through families ‚in HFI‚two copies of an abnormal gene are present ‚thus making it an auto recessive disorder‚ and frequently it is seen in person without a history of the disorder .HFI is a condition that affects fructose metabolism ‚basically the amount of Aldolase B’s substrate ‚F1P ‚changes when Aldolase B is deficient or doesn’t

ENZYMOLOGY DISORDERS OF METABOLISM By Wieslaw Faliszewski Our cells are using various types of substances in order to perform their functions. They also use them as a source of energy to perform all the required tasks. Some of those compounds come from the outside in the form of consumed food; others are synthesized in our body. Majority of those compounds have to be broken into simpler parts that can be used in different metabolic processes. The problem is‚ however‚ that most of the

Intensive Care Nursery House Staff Manual Inborn Errors of Metabolism INTRODUCTION and PATHOPHYSIOLOGY: Inborn Errors of Metabolism (IEM) comprise a group of disorders in which a single gene defect causes a clinically significant block in a metabolic pathway resulting either in accumulation of substrate behind the block or deficiency of the product. All IEMs are all genetically transmitted typically in an autosomal recessive or X-linked recessive fashion. The major categories are: Organic

lowering the activation energy for reactions; this speeds up the rate of the reaction process as illustrated in figure 3 below (Grisham‚ 2012). (Figure 3‚ http://4.bp.blogspot.com) An example of how enzymes work within the body is the breakdown of fructose. Energy obtained from carbohydrates goes through a process called glycolysis. Glycolysis a series of biochemical reactions in which one glucose molecule is oxidized into two pyruvic acid molecules and a small amount of adenosine triphosphate (ATP)

ways or are reversible. Fructose‚ a monosaccharide or simple sugar found in fruits‚ fruit juices and sweeteners such as honey and contains 6 carbons‚ is broken down by an enzymatic reaction. Fructose is a carbohydrate and is a good source of energy for the body‚ but it needs to be broken down by enzymes to become energy that can be used by the body. When fructose is consumed the first step begins with the enzyme fructokinase binding with the fructose which produces fructose-1-phosphate. The second
