  1. Glucose cycle

    Unreferenced stub auto yes date December 2009 Orphan date December 2009 The glucose cycle also known as the hepatic futile cycle occurs primarily in the liver and is the dynamic equilibrium between glucose and glucose 6 phosphate . This is important for maintaining a constant concentration of glucose in the blood stream . Function The glucose cycle is required for one of the liver functions the homeostasis of glucose in the blood stream. When blood glucose levels are in excess, glucose can be stored in the liver as glycogen . When glucose levels in the blood stream are low the glycogen can be catabolism catabolised and glucose may re enter the blood stream. The catabolic process occurs at the nonreducing end of glycogen. A phosphate group breaks the bond between C 1 of a glucose ring and the O that connects it to the next phosphorolysis . One glucose unit is thus split off. Glycogen with n glucose units is converted into G 1 P a PO sub 4 sub group now attaches to C1 where O used to and glycogen with n 1 glucose units by enzyme glycogen phosphorylase. G 1 P is then converted into G 6 P by enzyme phosphoglucomutase. A water molecule hydrolyses G 6 P to glucose, the enzyme is glucose 6 phosphatase. Cell specificity When glucose enters a cell it is rapidly changed to glucose 6 phosphate, by hexokinase . The glucose cycle can occur in liver cells due to a liver specific enzyme glucose 6 phosphatase , which catalyse the dephosphorylation of glucose 6 phosphate back to glucose.

  1. Glucose paradox

    Orphan date February 2009 Glucose paradox is a theory formulated by biochemist Dr. J. D. McGarry and his research associates. It is a theory that demonstrates the importance of lactic acid in carbohydrate metabolism . The paradox is that the large amount of glycogen 10 in the liver cannot be explained by its relatively minimal glucose absorption. After the digestion of carbohydrates and their entering the circulatory system in the form of glucose blood sugar , some glucose will be absorbed directly into the muscle tissue and will be converted into lactic acid in the Fermentation biochemistry anaerobic energy system rather than going directly to the liver and being converted into glycogen . This is true especially in situations of energy depletion and exercise. The lactate is then taken to and converted by the liver into the building blocks for liver glycogen. Much of the body s liver glycogen is produced indirectly from lactate rather than directly from glucose in the blood.

  1. Glucose clamp technique

    Interventions infobox Name PAGENAME Image Caption ICD10 ICD9 MeshID D015309 OtherCodes Glucose clamp technique is a method for quantifying insulin secretion and resistance. It is used to measure either how well an individual metabolizes glucose or how sensitive an individual is to insulin. ref Linda von Wartburg, What s a Glucose Clamp, Anyway? Diabetes Health. Nov 7, 2007. http www.diabeteshealth.com read 2007 11 06 5500 whats a glucose clamp anyway ref Two types of clamps are quite commonly used. The hyperglycemic clamp, which requires maintaining a high blood sugar level by perfusion or infusion with glucose, is a way to quantify how fast beta cells respond to glucose. The hyperinsulinemic clamp, which requires maintaining a high insulin level by perfusion or infusion with insulin, is a way ... glucose concentration is acutely raised to 125  mg dl above basal levels by a continuous infusion of glucose. This hyperglycemic plateau is maintained by adjustment of a variable glucose infusion, based on the rate of insulin secretion and glucose metabolism . Because the plasma glucose concentration is held constant, the glucose infusion rate is an index of insulin secretion and glucose ... ml by a continuous infusion of insulin. Meanwhile, the plasma glucose concentration is held constant at basal levels by a variable glucose infusion.

  1. Random glucose test

    Random glucose test is a blood sugar test taken from a non fasting subject. This test, also called random blood glucose RBG , assumes a recent meal and therefore has higher reference values than the fasting glucose test. Reference values The reference values for a normal random glucose test in an average adult are 70 140 miligram mg deciliter dl 3.9 7.8 milimole mmol l , between 140 200 miligram mg deciliter dl is considered pre diabetes, and 200 miligram mg deciliter dl is considered diabetes according to ADA guidelines you should visit your doctor or a clinic for additional tests however as a random glucose of 200 miligram mg deciliter dl does not necessarily mean you are diabetic .

  1. Oral glucose gel

    Orphan date October 2008 Oral glucose gel is an Over the counter drug over the counter medication , consisting primarily of dextrose and water , along with small amounts of other compounds. It is frequently used by Diabetes diabetics and those with hypoglycemia to raise their blood sugar when it becomes very low. Diabetics and other people with hypoglycemia, or low blood sugar, run out of energy when their glucose levels drop too low. These reactions can lead to unconsciousness if not treated in a timely matter. Reactions can occur suddenly, however glucose levels can be brought back to normal by eating or drinking carbohydrates. It is recommended by The American Diabetes Association ADA to carry something containing 15 grams of glucose at all times in order to treat these sometimes sudden reactions. Use Oral glucose gel is used to raise dangerously low blood glucose concentration or blood glucose that has dropped too low for the person s adaptive compensatory mechanisms to cope with. The gel may be self administered or given by an Emergency medical technician EMT responding to a diabetic emergency. As glucose molecules will absorb directly though oral tissue it is either swallowed directly, or allowed to stay in the mouth momentarily to facilitate rapid absorption via various areas of the mouth cavity http www.ncbi.nlm.nih.gov pubmed 9572913 and then swallowed to allow absorption into the blood via the small intestine. Product Oral glucose gel usually is found in single use tubes providing a dose of 15 grams of glucose, or resealable tubes with a total of 45 grams of glucose. It is usually fruit flavored. Common brands include GlucoBurst Glucose Gel manufactured by PBM Products Insta Glucose manufactured by Valeant and Glutose manufactured by Paddock Labs , as well as several store brands.
