Glucose Interactions With Other Nutrients and Drugs

  • Glucose  enhances sodium absorption  in the small intestine and this in turn enhances water absorption , so glucose  enhances water absorption [113] . This is why glucose is used in sport drinks and oral rehydration solutions [113,114] . Glucose (or other sugars) added to beverages in concentrations greater than 6-8% may slow gastric emptying of fluids and therefore slow water absorption [115] .
  • Glucose  enhances fructose absorption [116,117] .
  • Glucose in large amounts, especially when given as an intravenous injection, may  lower blood levels of vitamin B1 (thiamin) , phosphate , magnesium and potassium . This is known as refeeding syndrome , which is especially dangerous in alcoholics, who often already have several vitamin and mineral deficiencies [118] .
  • A combination of alcohol and carbohydrates   (sweet liqueurs, vodka and soft drinks, rum and cola, gin tonic, or alcohol with carbohydrate snacks) may trigger  reactive hypoglycemia  with hunger, shakiness, dizziness and weakness within 1-3 hours after consumption [119] . Mechanism: carbohydrates stimulate insulin secretion and alcohol enhances its effect what results in an excessive drop of blood glucose [119,120] .
  • Proteins ( amino acids )  trigger the release of insulin, and they  reduce the increase of blood glucose levels after meals  when added to a carbohydrate meal:  slightly  in healthy individuals and  markedly  in those with diabetes 2 [121] . In one 2007 study in healthy individuals, 3-7 grams of amino acids leucine, isoleucine, valine, lysine and threonine in various combinations added to glucose drink reduced the rise of blood glucose levels after meals for more than 40% related to meals containing glucose alone; this effect was probably due to increased release of insulin triggered by amino acids [54] . In the same study, 18 grams  whey protein  added to a glucose drink reduced blood glucose levels after the meals by more than 50%.
Glucose Production Glucose as a sweetener is produced from starch, in the United States usually from corn (maize) starch [87] and in other countries also from wheat [88] , barley, sorghum, rice or potato, tapioca (cassava) and sago palm starch.

  • Circulating glucose concentrations do not drop below  mmol L −1 even in prolonged starvation.
  • During starvation, the brain must be supplied with fuel in the form of glucose or ketone bodies.
  • Carbohydrate reserves are depleted after 24 h of starvation.
  • In prolonged starvation, gluconeogenesis provides the glucose oxidised by the brain.
  • The major substrates for gluconeogenesis are amino acids derived from skeletal muscle protein breakdown.
  • Circulating ketone body concentrations rise during prolonged starvation.
  • During starvation, most tissues utilise fatty acids and/or ketone bodies to spare glucose for the brain.
  • Glucose utilisation by the brain is decreased during prolonged starvation as the brain utilises ketone bodies as the major fuel.
  • High concentrations of ketone bodies result in significant excretion of ketones.
  • Urinary ketones are excreted as ammonium salts derived from the renal metabolism of glutamine with the carbon skeleton being recovered through renal gluconeogenesis.

Recently, a specific peptide inhibitor for ATGL was isolated from white blood cells, specifically mononuclear cells. This peptide was originally identifed as being involved in the regulation of the G 0 to G 1 transition of the cell cycle . This peptide was, therefore, called G0G1 switch protein 2 (G0S2). The protein is found in numerous tissues, with highest concentrations in adipose tissue and liver. In adipose tissue G0S2 expression is very low during fasting but increases after feeding. Conversely, fasting or PPARα-agonists increase hepatic G0S2 expression. The protein has been shown to localize to LDs, cytoplasm, ER, and mitochondria. These different subcellular localizations likely relate to multiple functions for G0S2 in regulating lipolysis, the cell cycle , and, possibly, apoptosis via its ability to interact with the mitochondrial antiapoptotic factor Bcl-2. With respect to ATGL regulation, the binding of the enzyme to LDs and subsequent is dependent on a physical interaction between the N-terminal region of G0S2 and the patatin domain of ATGL.

Actovegin is a deproteinated, pyrogen- and antigen-free hemodialysate of calf blood. It is manufactured from calf blood in several steps by ultrafiltration: here, the manufacturer uses different cut off sieves: first, an ultrafiltration step employing a cut off of 6 kD is performed, followed by a vacuum distillation step and removal of the precipitate by filtration ( urn) and titration to pH . Afterwards, the product is subjected to sterile filtration with prefilters of pm and pm and stored at 2-6 °C for more than 14 days and subsequently filtered ( pm) and again titrated to pH . After subsequent pH titration steps, the product is again subject to filtration (7 pm and pm) and another ultrafiltration step with a lOkDa cut off, followed by sterile filtration with prefilters of pm and pm. After another storage period at 2-6 °C for more than 56 days, the final precipitate is removed by filtration ( pm) and diluted to a nominal concentration to 200 mg/ml dry weight. Finally, deproteinization is completed by sterile filtration with prefilters of pm and pm. The analysis of the final product shows that it contains a mixture of natural substances: both inorganic components like common blood electrolytes (. chloride, phosphate, sodium, potassium, calcium, and magnesium, several sources for nitrogen, amino acids, peptides, glucose, acetate and lactate) and organic components like amino acids, a number oligopeptides, nucleosides, glycosphingolipids and products of the intermediary metabolism.
