Meteoritic Abundances of Fatty Acids and Potential Reaction Pathways in Planetesimals [PDF]
Icarus, 2019, 319, 685-700, 2018 The origin of fatty acids on the prebiotic Earth is important as they likely formed the encapsulating membranes of the first protocells. Carbon-rich meteorites (i.e., carbonaceous chondrites) such as Murchison and Tagish Lake are well known to contain these molecules, and their delivery to the early planet by intense early meteorite bombardments ...

Regulation of Abscisic Acid Biosynthesis [PDF]
Plant Physiology, 2003 Plant growth and development are regulated by internal signals and by external environmental conditions. One important regulator that coordinates growth and development with responses to the environment is the sesquiterpenoid hormone abscisic acid (ABA).

Food Frontiers, EarlyView.In this study, we showed the potential therapeutical properties, namely, antioxidant, antimicrobial, enzyme inhibitory, and antitumor, of Liquidambar orientalis extracts from its aerial parts using methanol, ethyl acetate, and water. The methanolic extract of exhibited the highest phenolic and flavonoid content, demonstrating superior antioxidant ...

Helvetica Chimica Acta, EarlyView.Abstract In senescent leaves of banana (Musa acuminata) hypermodified fluorescent chlorophyll (Chl) catabolites (hmFCCs) accumulate and give these leaves an easily observable blue fluorescence. Non‐fluorescent Chl‐catabolites (NCCs) are not detected, the typical colourless Chl‐catabolites that accumulate in most de‐greened plant leaves. Here, we report

Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT Starch accumulation in plants provides carbon for nighttime use, for regrowth after periods of dormancy, and for times of stress. Both ɑ‐ and β‐amylases (AMYs and BAMs, respectively) catalyze starch hydrolysis, but their functional roles are unclear.

Geometric-algebraic approach to aqueous solutions of diprotic acids and its buffer mixtures [PDF]
arXiv, 2023 A closed-form analytical expression for $\ce{[H3O+]}$ has been obtained for aqueous solutions of diprotic acids and its soluble salts. This formula allows to calculate the pH of aqueous solutions of diprotic acids, their buffer solutions, and the titrations of these two by a strong base, from the values of p$K_1$, p$K_2$, and the effective ...
