Abstract
It is recognized that natural organic molecules can exhibit position-specific isotopic fractionations (i.e., differences in isotopic composition for a single element between non-equivalent molecular sites). For example, lipids can exhibit up to ~30 ‰ difference in ^(13)C/^(12)C between adjacent carbons as a result of fractionations arising during decarboxylation of pyruvate in lipid biosynthesis [1]. Little in detail is known about such isotope effects in natural products, but it seems possible that observations of isotopic ordering of carbon could distinguishing among the mechanisms and conditions of biosynthetic reactions. And, such position specific isotope effects may be inherited by alkanes produced from thermal degredation fatty acid chains, perhaps modified as functions of the conditions and mechanisms of thermal maturation.
