Food Tests: How To Test For Protein | Biology Practicals

Hazel and Emilia demonstrate the food test to test for the presence of protein. To carry out this test, mix the food sample with Biuret reagent, shake, and if protein is present a purple solution will form.

A special thank you to Sancton Wood School in Cambridge for letting us use their lab to film in.

These videos are designed to help with your GCSE and IGCSE science revision.

To keep up to date with my Science with Hazel videos and support:

Hazel completed her undergraduate degree at St John's College, the University of Cambridge. She then did a PGCE (Post-Graduate Certificate of Education) before qualifying as a science teacher. She now works full time as a professional tutor.

Material required for Level 9 is included.

Thanks. I cant understand experiments by reading so ths really helps

we can also add sodium hydoxide + coppersulphate for testing protein

NICE!! No matter how high they climb...or high far they reach....they just can't seem to get out of the kitchen
😁😁

Shouldn't it be with copper sulphate(CuSO4) solution and caustic sode(NaOH)?

[ammarkalalib]

Why you didnt use 5cm cube of dilute sodium hydroxide and 5 cm cube of copper sulfate

[pakohlomani]

That's it .I expected some thing long

[siphogunde]

why does my teacher talk about adding sodium hydroxide and copper sulfate
