Step 1
Sudan III is a dye that is used to stain lipids (fats) in biological samples. It is a non-polar dye that has an affinity for lipid molecules. Show more…

Lipids Sample Code Letter Sudan III's Result (lipid) Color +/- Distilled Water W Margarine M Crisco C Whipped Cream K Corn Starch F Table 3.3 - Please indicate the color of your result and whether it was + or - for the Sudan III test. Why does the Sudan III reagent bind to the samples that they did? Which compound(s) yielded the most positive result and does this support what you know about the lipid or fat content of these substances? Why is it important to include distilled water as a test sample in each of the tests (Benedict's, Lugol's, Biuret, and Sudan III) we performed?

Provided that Sudan IV stain is used to test for the presence of lipids, which component/s of the periderm will yield a positive result? Why is this so?

24. A sample that does contain the molecule being tested is called (a) positive control, (b) unknown, (c) soluble, (d) independent variable, (e) a protein. 25. When lipids are stained with Sudan dye (a) two layers appear, (b) they absorb the red dye, (c) they turn violet, (d) one red layer appears, (e) b & d are correct. 26. A sample that does not contain the molecule being tested is called (a) insoluble, (b) unknown sample, (c) positive control, (d) dependent variable, (e) a negative control. 27. Peptide bonds (a) join amino acids together, (b) join fatty acids to glycerol, (c) are formed by dehydration, (d) a & b are correct, (e) a & c are correct. 28 The protein assay was used to determine (a) the presence of proteins, (b) the concentration of proteins, (c) the amount of carbohydrate bound to protein, (d) the ratio of proteins to lipids in a sample, (e) the volume of BSA.
