Virtuаl Lаb - Sudаn IV Test fоr Fat/Lipid The Sudan IV test fоr lipids uses mоlecules that are orange reddish in color. Lipid molecules and Sudan dye molecules are both hydrophobic in nature. Therefore, when a hydrophobic region of lipid molecules encounters a Sudan reagent molecule, the Sudan molecule sticks to the hydrophobic tails of the fatty acids of the lipid and stains the area that the lipid resides an orange reddish color. If there are no hydrophobic molecules present, the dye molecules do not stick well but will leave a light pink color behind only. To be considered positive, the sample area on the filter paper with Sudan dye must show an increase in color retention or aggregation of color (orange/red) when compared to the negative control (water + Sudan IV). It works because of the physical attraction of the Sudan IV dye and the lipid molecules on the filter paper. Vegetable oil consists primarily of triglycerides composed of a glycerol molecule and 3 fatty acids (the prefix “tri” refers to the number three) and often used as a positive control for the Sudan IV test. The filter paper above was dotted with 6 different substances and then, the Sudan IV reagent was added on top of the previously dried substance spots. If the substance retained the Sudan IV dye more than what is seen with the negative control (water), then the test is positive for lipids. The darker the spot, the more positive the result.
