Benedict’s, Biuret, Starch & Lipid Tests | A-level Biology | OCR, AQA, Edexcel HD

https://goo.gl/31T06Y to unlock the full series of AS, A2 & A-level Biology videos created by A* students for the new OCR, AQA and Edexcel specification. In this video we cover the major qualitative food/biological molecules tests. This includes the iodine test for starch, Benedict’s test for reducing sugars (and how this procedure can be modified for non-reducing sugars and quantitative testing), the emulsion test for lipids and Biuret test for proteins. We’ll round everything up by working through a typical exam question.
