The prebiotic chemistry of nucleotides
Origins of Life, 1984Diiminosuccinonitrile (DISN), formed by the oxidation of diaminomaleonitrile (DAMN), has been investigated as a potential prebiotic phosphorylating agent. DISN effects the cyclization of 3'-adenosine monophosphate to adenosine 2', 3'-cyclic phosphate in up to 39% yield. The mechanism of this reaction was investigated.

Obesity was probably rare in ancient times, with the current increase starting in the Industrial Revolution of the eighteenth century, and becoming much more widespread from about 1950, so concurrent with the increased consumption of carbohydrates from cereals in the Green Revolution.

The evolution of the prebiotic atmosphere
Origins of Life, 1984One-dimensional radiative convective and photochemical models are used to estimate the vertical temperature structure and composition of the earth's prebiotic atmosphere. Greatly enhanced CO2 levels (100-1000 times present) are required to keep the mean surface temperature above freezing in the face of decreased solar luminosity during the earth's ...

Struvite and Prebiotic Phosphorylation
Science, 1973Struvite, MgNH 4 PO 4 ⋅6H 2 O, rather than apatite or amorphous calcium phosphate is precipitated when phosphate is added to seawater containing more than 0.01 M NH 4 + ions.

Cyanoacetylene is an earlier intermediate in a proposed prebiotic synthesis of cytosine, while cyanoacetaldehyde is a later intermediate. There is no scientific basis for the claim that cyanoacetaldehyde is more plausibly prebiotic than cyanoacetylene in this context.

Dietary fiber and prebiotics exert a great impact on health-promoting food for mankind. Under this aspect a general overview is given about the bioavailability of carbohydrates and their influence on dietary fiber intake and about the developing of the prebiotic concept and specific functional foods. Moreover, the occurrence and chemical composition of

Based on modern geochemistry's view of the atmospheric and geological conditions on the primordial Earth ∼3.8–4 billion years ago, the most realistic scenario for the formation of amino acids and peptides in chemical evolution is discussed, including possible reasons for sequence preferences in early proteins and for biohomochirality.
