positive result. The positive result ranged colours from reddish orange (Identifying Macromolecules). Based on class observations (refer to table two)‚ the only solvents that contained lipids were vegetable oil and slightly skim milk. Subsequently‚ the Sudan IV solution has the ability to liquefy in lipids‚ except with water. Thus‚ if it reacts with lipids a colour change will occur. It will turn into red colour which is a positive result in this case. As discussed in class‚ unsaturated fat is a lipid
