Biotin. Its place in evolution

Abstract

In the previous article we try to give an explanation for the success of models of enzymatic reactions in which coenzymes play a role. However, one vital cofactor that has thus far not yielded appreciably to this approach is biotin. We attempt to show that biotin presents a fundamentally new sort of problem to bioorganic chemistry; this problem requires consideration both of the origin of life and subsequent evolution in any attempt to understand the anomalies offered by this cofactor.
