Racemic Phospholipids for Origin of Life Studies [PDF]
, 2020 Although prebiotic condensations of glycerol, phosphate and fatty acids produce phospholipid esters with a racemic backbone, most experimental studies on vesicles intended as protocell models have been carried out by employing commercial enantiopure ...

Crystal structure of β-d,l-allose
Acta Crystallographica Section E: Crystallographic Communications, 2015 The title compound, C6H12O6, a C-3 position epimer of glucose, was crystallized from an equimolar mixture of d- and l-allose. It was confirmed that d-allose (l-allose) formed β-pyranose with a 4C1 (1C4) conformation in the crystal.

Co-crystallization of Praziquantel : conglomerate and racemic compound nucleation rates [PDF]
, 2023 International audiencePraziquantel (PZQ) is widely used to treat schistosomiasis. However, this chiral pharmaceutical is still produced as a racemic compound (both enantiomers crystallize together in the crystal lattice) while only the R enantiomer is ...

Pasteur made simple – mechanochemical transformation of racemic amino acid crystals into racemic conglomerate crystals [PDF]
, 2020 Conglomerate crystallization is required for many deracemization or enantioenrichment protocols. Here, we report the metal-mediated mechanochemical transformation of racemic compounds of some proteinogenic amino acids – valine, leucine and isoleucine ...
