Potentially prebiotic syntheses of condensed phosphates.

Orig. Life Evol. Biosph. 26(1) , 15-25, (1996)

In view of the importance of a prebiotic source of high energy phosphates, we have investigated a number of potentially prebiotic processes to produce condensed phosphates from orthophosphate and cycl...

A possible prebiotic synthesis of pantetheine, a precursor to coenzyme A.

Nature 373(6516) , 683-5, (1995)

The involvement of coenzyme A in many enzyme reactions suggests that it acted in this capacity very early in the development of life on Earth. Particularly relevant in this regard is its role in the a...

Optical rotation of noncovalent aggregates.
