Niketan Avani October 5, 2010 Section: N6 Lab 3 Take-Home Assignment 1. DNS was used to measure sugar concentration in this lab, and it reacts with the aldehyde functional group. 2. Biuret was used to measure protein concentration in this lab, and it bonds to the peptide bonds in an amino acid. 3. Cs = 2.3 mg/mL As = 0.19 Au = 0.77 Cu = ? Cu = Cs Au = (2.3 mg/mL)(0.77) = 9.32 mg/mL As (0.19) 4. Yes, patient #3’s urine appeared to contain hemoglobin. One would measure a sample using a spec-20, and then comparing it to a standard sample that has a known concentration of hemoglobin in order to figure out the amount of hemoglobin that was in patient #3’s urine. The blank would only contain water. The standard would contain normal urine.
