What is the difference between Sudan IV Lipid Test and Translucence Lipids Test?
We just did a lab on this in my bio class.The Sudan test uses Sudan IV reagent. If a lipid or fat is present, red globs of fat will appear at the top of the solution. If not, there won't be a reaction.The translucence test is when a drop of liquid is placed on an unglazed paper. Water will dry up and leave the paper crinkly. An oil or fat will spread out, and leave a stain, not really drying, and making the paper look translucent.
