What the sim shows
Add prepared Biuret reagent to the food sample. Purple indicates protein; the reagent stays blue when protein is absent. Compare with a known protein control. The drop count stages the demonstration; it does not measure protein concentration.
- Left: chosen sample. Right: known protein control. Both receive the same prepared reagent.
