Lysine-rich proteinoid can synthesize peptides with inorganic pyrophosphate instead of ATP (Fig. 3)27). Pyrophosphate has been proposed as an evolutionary precursor of ATP30>. In some microorganisms, pyrophosphate serves as a source of energy in fermentation. The experiment of Fig. 3 compares equimolar amounts of these two energy-rich phosphates. The ratio of yield from ATP to that from pyrophosphate in one experiment was 3.7 27). 

In 1944, Emerson, Stauffer, and Umbreit proposed that the function of light energy in photosynthesis is the formation of energy-rich phosphate bonds (p. 107). In their model (hereafter, the Emerson model ), the free energy necessary to drive both C02 fixation and reduction came from these energy-rich phosphate bonds (i.e., ATP), produced as a result of light absorption by a chlorophyll-containing protein. 

The reaction of reverse transfer of energy-rich phosphate residues from ATP to PolyPs and from PolyPs to ADP, thus linking energy-rich pools, was discovered by Kornberg and co-workers (Kornberg el al., 1956 Kornberg, 1957 a,b) ...

The above ingenious reaction was brought about by heating the mixture to 150° for 1-5 hr., the yield of (XXIII) being 49 per cent. Thus there is a redistribution of energy-rich phosphate bonds. 

If depressants inhibit the utilization of energy-rich phosphates, phospholipid biosynthesis might be expected to be affected. With a dose of 60 mg/kg body weight of thiopentone [5-ethyl-5-(l-methylbutyl)-2-thio-barbitone], Dawson and Richter (1950b) convincingly demonstrated a reduction in the rate of transfer of labeled phosphate from the water-soluble pool to the phospholipids of mouse brain. This was not due to the hypothermia induced by the anesthetic. Ansell and Dohmen (1957) confirmed this for a number of phospholipids, including phosphatidylcholine and -ethanolamine. It was subsequenUy shown that the phosphorylation of the bases choline and ethanolamine was unaffected (Ansell, 1960). This was presumably a consequence of the unchanged level of ATP.

Why are energy-rich phosphates rich in energy It means, why is the free energy of hydrolysis of certain selected phosphates a few kilocalories greater than that of the more usual ones ... 

The quantitative evaluation of these contributions to the energy of the different types of energy-rich phosphates is summed up in Table VII.
