Glucose reactions

The autotropic pathway for acetate synthesis among the acetogenic bacteria has been examined (67). Quantitative fermentation of one mole of glucose [50-99-7] yields three moles of acetic acid, while two moles of xylose [58-86-6] C H qO, yields five moles. The glucose reaction is...

Drug/Lab test interactions False-positive urine glucose reactions may occur with penicillin therapy if Clinitest, Benedict s Solution, or Fehling s Solution are used. It is recommended that enzymatic glucose oxidase tests (such as Clinistix or Tes-Tape) be used. Positive Coombs tests have occurred. High urine concentrations of some penicillins may produce false-positive protein reactions (pseudoproteinuria) with the P.870...

FIGURE 7-6 Formation of the two cyclic forms of D-glucose. Reaction between the aldehyde group at C-l and the hydroxyl group at C-5 forms a hemiacetal linkage, producing either of two stereoisomers, the a and fi anomers, which differ only in the stereochemistry around the hemiacetal carbon. The interconversion of a and fi anomers is called mutarotation. 

Hass and Byrne 28-30) and Segal (31) described in 1959 and 1960 the ability of liver microsomal glucose-6-phosphatase to catalyze an exchange reaction involving transphosphorylation between glucose-6-P and 14C-glucose [reaction (2a)]. The former workers (30) demonstrated that...

Morrison and Ebner (1971c) were concerned with the kinetic effects of a-lactalbumin with either glucose or AT-acetylglucosamine. Thus, a-lactalbumin appears to cause the following (1) alternate pathways, (2) reductions in for either substrate, (3) a decrease in velocity with the A-acetylglucosamine reaction, and (4) an increase in velocity with the glucose reaction.

Reaction condition 0.5 mmol glucose, 0.5 mmol lauric acid, 50 mg Chirazyme L-2 lipase, 0.4 mL mixture of ethyl methylketone and hexane (4 1, vol/vol), 59°C, 650 rpm, 48 h. 

The fermentation of glucose (reaction 1) proceeds by the Embden-Meyerhof glycolytic pathway. The electrons generated reduce COj formed in the fermentation with the formation of acetate (reaction 2), which occurs by the acetyl-CoA pathway described below. The result is the formation of three mol of acetate out of one mol of glucose (reaction 3).
