Origins of Chirality in Nature: A Reassessment of the Postulated Role of Bentonite

Abstract

Bondy and Harrington have proposed that selective binding of L isomers of amino acids and D isomers of sugars to bentonite is the mechanism by which the chirality of molecules in living cells was originally established. Further experiments indicate that the observations of Bondy and Harrington are better explained in terms of the effects of the binding to bentonite of the products of radiochemical decomposition.
