Glucose challenge was conducted through intravenous application of 50% glucose (0.3 g/kg of body weight) in 1 min periods in the antecubital vein. The clock was restarted at the beginning of glucose application. Samples used for measuring insulin and c-peptides were taken precisely in +2 min‚ +4 min‚ +6 min and +8 min after initiation of glucose administration. Samples for measuring glycemia were taken in +2 min‚ +4 min‚ +6 min and +8 min. Upon completed sampling‚ insulin infusion was stopped‚ while

involving the appearance of NADPH. Sucrose and glucose concentrations were calculated from the concentration of NADPH formed by the reaction of glucose-6-phosphate and NADP+. Spectrophotometric absorbance readings were taken at 340nm‚ this is because NADPH absorbs strongly at this wavelength‚ whilst NADP+ does not (1015MSC‚ 2010). The concentration of glucose and sucrose in Powerade was found to be 0.43g/100mL and 7.36g/100mL‚ whereas the concentration of glucose and sucrose in Gatorade was found to be

RESEARCH QUESTION How does the glucose concentration effects the time taken for the potassium permanganate to decolourise from purple to colourless ? HYPOTHESIS The higher the glucose concentration the shorter the time taken for the potassium permanganate to decolourise from purple to colourless.

The Benedict test is a test for monosaccharides; simple sugars like glucose or fructose (fruit sugar). In contact with monosaccharides‚ the Benedict solution turns from blue to pink. Does Sample A contain monosaccharides? _________ Note: Disaccharides such as sucrose (table sugar) and lactose (milk sugar)

From the experiment‚ the blood glucose concentration for Patient A is 5.6 mmol/L(Refer to Table 1). The blood glucose level for Patient A is normal as 5.6mmol/L is in the normal range. Urine sample from Patient A was tested and it is shown that there was no glucose and sodium present. The results showed that Patient A is healthy and could act as a control in this investigation. Secondly‚ patient B is suspected to suffer from diabetes mellitus. The blood glucose concentration for Patient B is 111mmol/L

lab is to measure urinary glucose (a known and unknown sample) using two quantitative tests: colorimetric strip test and o-toluidine test. Urinary glucose is the main focus for this lab due to its involvement with diabetes‚ a disease defined by the abnormal regulation of insulin. The most effective method for monitoring glucose is through blood glucose compared to urinary glucose. It has been discovered that urinary glucose is not a good measure of changes in blood glucose because: (1) the bladder

it is hypothesized that Glucose would have the highest fermentation rate because the structure of glucose suggests that it would require less work to break down into the pyruvate. Because of its simple molecular structure‚ it can be decomposed the quickest. Within glucose‚ starch‚ truvia‚ sucralose‚ saccharin‚ fructose‚ maltose‚ sucrose and lactose‚ there will be different fermentation rates because sugars like fructose have a 5-ring structure differing greatly from glucose. Lactose won’t ferment

DETERMINING THE GLUCOSE CONTENT OF AND ORANGE USING GOD-PAP ASSAY Every fruit has a sweet taste only that some are sweeter than others. The sweetness of most fruits come from its sugar content and these sugars that the fruits contain are known as invert sugars. In this experiment‚ an orange was used. An orange which is an excellent source of vitamin C gets its sweetness from natural sugars which are sucrose‚ glucose and fructose (livestrong.com). In this experiment the concentration of glucose in an orange
