A 50.0 ml juice extract is colorimetrically assayed using Nelson's test. One milliliter (1.00 mL) of the solution and the standard glucose solution (concentration: 1mg/mL) were treated with freshly prepared Nelson's reagent and arsenomolybdate reagent and then diluted to 10.0 mL separately in properly labeled test tubes. Absorbance at 480 nm for the standard is 1.702 and for the sample, 0.926.

What can you say about how Norbixin and Beta Carotene will behave in your experiment just by looking at the circled differences in their structures? ( the experiment was thin Layer Chromatography. finding compounds in spinach juice using their polarity and retention factor, Rf= distance traveled by the compound / distance traveled by the solvent). (Please do not copy and past some idea from other websites. I can do that myself) undefined
