The pepper alkaloid piperine is a nontoxic, natural dietary compound with a broad range of physiological activity. The present work is the first demonstration of its interaction with a mammalian protein. Circular dichroism (CD) spectroscopy was used to reveal and analyze the binding of piperine to a lipocalin protein. Induced CD spectra measured in pH 7.7 phosphate buffer at 37\^A°C demonstrated reversible, non-covalent association of piperine with bovine \^I˛-lactoglobulin (BLG), the major whey protein in milk. The binding parameters (Ka \^a\textperthousandˆ 8 \u A— 104 M-1
