Introduction In this experiment we are going to test for glucose. A body fluid sample is detected at a scene of crime and a sample taken using cotton bud. The prime suspect is a diabetic. No DNA has been found at the scene. Carry out the necessary forensic tests and present a forensic report. Many common sugars, with the exception of sucrose, act as reducing agents, and are therefore known as reducing sugars. Reducing sugars can reduce copper (II) ions in boiling alkaline solution to copper (I). Before you can perform the test on the body fluid sample, you must make up a 1% glucose solution to act as a control solution. ...read more.


Method for making the standard solution First of all we got a plate and we put it on the weighing scales then we put in 1.98g of powder in the plate then we got the volume metric flask that had our standard solution in and also we got a spatula and a funnel the we put the funnel on the top of the volume metric flask and we poured some powder down the funnel and we added some sterilised water so the powder will go throw faster and we pushed it down with a spatula then we washed the funnel and the plate with more sterilised water then we filled the sterilised water up to the line on the volume metric flask then we left it. ...read more.


(Using the standard solution you knew that a positive test look's like. Sample a came from the scene of crime came positive this puts the suspect at the crime scene. Sample B shows us what a negative test looks like because it only contained water. Evaluation Benedict's is a good test for glucose every sensitive test possible chance of contamination did not carry the practical out under sterile conditions could have asked me sample with a clinistrix test can give you three results only a small amount of glucose (light) slightly more glucose (medium) lots of glucose (dark) Vocational implications A forensic scientist would not test for glucose this way Special machine for testing the sample for less chance of contamination more accurate (results) process - gas chromentphry. ?? ?? ?? ??

    Following this preliminary, the closest form of measurement received was by measuring to the nearest mm, to measure to a greater degree of specificity would be extremely difficult. In the main investigation care is needed when placing the discs into the centre of each agar plate as some of them failed to be in the correct place.

    5. Then we mixed the Benedict's solution and the glucose into the test tube that already contained the solution. 6. Then we put the Bunsen burner on and placed the beaker that had the water in it on top on the gauze mat that was on the tripod and we heated the beaker and put the test tube in the beaker.
