Phenylthiourea ptu
WebPhenylthiourea (PTU) is an enzyme inhibitor. Setup: Looked at 3 test tubes with potato extract and cathecol. - one control with no PTU Seeing if competitive or noncompetitive by looking at color in solution. - The darker we saw the more reactive was the . enzyme. WebFor experiment 6, Inhibitor Effects – Inhibiting the Action of Catechol Oxidase, it was hypothesized that the addition of phenylthiourea (PTU) would keep the enzyme reaction from occurring. The hypothesis was able to be accepted due to the fact that the tubes which contained the PTU showed very little change in pigment.

WebA member of the class of thioureas that is thiourea in which one of the hydrogens is replaced by a phenyl group. Depending on their genetic makeup, humans find it either very bitter-tasting or tastele ss. This unusual property resulted in N-phenylthiourea being used in paternity testing prior to the advent of DNA testing. WebCatechol oxidase is also inhibited by phenylthiourea (PTU) which binds to a copper atom in the enzyme.
