Racemic 2-hydroxymethyltrithia[5]heterohelicene (2-HT), which has a labile helical structure was incorporated into serum albumins of nine species in 1% ethanolic aqueous solution, giving 1:1 complexes which exhibited induced circular dichroism spectra with species specificity. The application of 2-HT to bovine serum as a probe for chiral recognition revealed that the serum itself manifested an apparent chiral discrimination between enantiomers of 2-HT.
