Towards Prebiotic Chemistry on Titan: Impact experiments on organic haze particles [PDF]

open access: yes2024 Planet. Sci. J. 5 68
Impacts are critical to producing the aqueous environments necessary to stimulate prebiotic chemistry on Titan's surface. Furthermore, organic hazes resting on the surface are a likely feedstock of biomolecules. In this work, we conduct impact experiments on laboratory-produced organic haze particles and haze/sand mixtures and analyze these samples for

A " NEW " DISORDER OF ISOLEUCINE CATABOLISM

open access: yesThe Lancet, 1971
A disorder of isoleucine catabolism was found in a child with intermittent metabolic acidosis. The block occurs at the stage of propionate synthesis, and two intermediates--alpha-methylacetoacetate and alpha-methyl-beta-hydroxybutyrate--accumulate. The condition is apparently inherited.

Antimitotic action of cornin as a biologically active polypeptide. I. Biochemical properties of cornin [PDF]

open access: yes, 1965
We succeeded in the extraction of a substance from beef cornea and rabbit muscle, that markedly inhibits mitosis of sea urchin eggs. The substance extracted from beef cornea is non-dialysable and it can be separated into three fractions by DEAE-cellulose

Crystal structure of a new polymorph of (2S,3S)-2-amino-3-methylpentanoic acid

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2018
A new polymorph of (2S,3S)-2-amino-3-methylpentanoic acid, l-isoleucine C6H13NO2, crystallizes in the monoclinic space group P21 with four independent molecules in the asymmetric unit. The molecules are zwitterions. In the crystal, N—H...O hydrogen bonds
