Hypothesis Question: How does one stop the “burning” effect of chilli peppers? Hypothesis: Molecules in liquids, such as milk and water, dissolve or bind with the molecule in peppers that cause the pungency, and thus prevent that molecule from binding with taste and pain receptors on the tongue and mouth.

Chemical Principles Capsaicin- Hydrophobic molecule Many derivatives of capsaicin made by changes in the hydrocarbon tail. The other forms have lower Scoville unit ratings, thus not as spicy. The fucntional group of hydrocarbon tail is important to the effectiveness of capsaicin (or derivatives) binding to taste and pain receptors. If chilli peppers are rubbed on the skin, water has no effect. Petroleum jelly does however. Proof of hydrophobic nature. Water cannot dissolve capsaicin.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
