Racemization of amino acids in sediments from saanich inlet, british columbia.

K A Kvenvolden, E Peterson, F S Brown.   

Abstract

In sediments spanning the last 9000 years from Saanich Inlet L enantiomers of amino acids are most abundant, but the percentages of D enantiomers increase with age, apparently because of partial racemization. Of the amino acids measured, glutamic acid and alanine show the greatest degree of racemization; leucine, isoleucine, and valine show the least.
