Stationary points of Equation (1) and (2) yielding the most stable cis-MF conformer, computed at MPWB1K-D3(BJ)/6-31G(d, p) theory level, and Equation (3) and (4) yielding the most stable syn, cis-GA conformer, computed at BHLYP-D3(BJ)/6-31G(d, p) level of theory. PRC stands for prereactant complex and TS for transition state. Distances are given in Å. The energetics can be found in Table 1. -- Chempluschem

Atomistic Modeling of Methyl Formate and Glycolaldehyde Formation on Interstellar Dirty Ice Mantles via a “Radical + Ice” Mechanism

by Keith CowingSeptember 22, 2025September 22, 2025

Methylformate (MF) and glycolaldehyde (GA) are two primogenital organic molecules detected in both cold and warm regions of the interstellar medium (ISM).

Aqueous chemistry inside meteorite parent bodies allows the formation of prebiotic molecules crucial for all life in the early solar system. We present a reaction mechanism suitable for vitamin B3 synthesis in this environment, which is experimentally verified in the literature. Vitamin B3 was transported to the Hadean Earth by meteorite falls and initiated redox chemistry in the form of NAD(P)H, potentially participating in the origins of life. -- ChemPlusChem

Prebiotic Vitamin B3 Synthesis in Carbonaceous Planetesimals

by Keith CowingApril 23, 2024April 23, 2024

Aqueous chemistry within carbonaceous planetesimals is promising for synthesizing prebiotic organic matter essential to all life. Meteorites derived from these planetesimals delivered these life building blocks to the early Earth, […]
