Which blood component reacts with phenolphthalein and hydrogen peroxide to produce a pink colored indicator?

Hemoglobin

Explanation: The Kastle-Meyer test relies on the iron in hemoglobin, which is the iron-containing portion of a red blood cell, to promote the oxidation of phenolphthalin to phenolphthalein. Phenolphthalin is colorless, but in the presence of blood and hydrogen peroxide, it changes to phenolphthalein, which makes the solution pink.
