Synthesis of α-amino and α-hydroxy acids under volcanic conditions: implications for the origin of life
Facile synthesis of α-hydroxy and α-amino acids is observed at temperatures from 145 to 280 °C with catalytic Ni2+, with cyano ligands as source for C and N, and with CO as a reductant and as a source for C. Implications for the problem of the origin of life are discussed.
Coupling of functional hydrogen bonds in pyridoxal-5′-phosphate- enzyme model systems observed by solid-state NMR spectroscopy
We present a novel series of hydrogen-bonded, polycrystalline 1:1 complexes of Schiff base models of the cofactor pyridoxal-5′-phosphate (PLP) with carboxylic acids that mimic the cofactor in a variety of enzyme active sites. These systems contain an intr
