Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...
More generally, in the medical literature, the Pasteur effect refers to how the cellular presence of oxygen causes in cells a decrease in the rate of glycolysis and also a suppression of lactate accumulation. The effect occurs in animal tissues, as well as in microorganisms belonging to the fungal kingdom. [2] [3]
Like other simple aliphatic amines, ethylamine is a weak base: the pK a of [CH 3 CH 2 NH 3] + has been determined to be 10.8 [8] [9] Ethylamine undergoes the reactions anticipated for a primary alkyl amine, such as acylation and protonation. Reaction with sulfuryl chloride followed by oxidation of the sulfonamide give diethyldiazene, EtN=NEt. [10]
Dimethylamine is a weak base and the pKa of the ammonium CH 3-NH + 2 -CH 3 is 10.73, a value above methylamine (10.64) and trimethylamine (9.79). Dimethylamine reacts with acids to form salts, such as dimethylamine hydrochloride, an odorless white solid with a melting point of 171.5 °C.
α-Alkyltryptamines are a group of substituted tryptamines which possess an alkyl group, such as a methyl or ethyl group, attached at the alpha carbon, and in most cases no substitution on the amine nitrogen.
SR9009, also known as Stenabolic, is a research drug that was developed by professor Thomas Burris of the Scripps Research Institute as an agonist of Rev-ErbA (i.e., increases the constitutive repression of genes regulated by Rev-ErbA) [1] with a half-maximum inhibitory concentration (IC 50) = 670 nM for Rev-ErbAα and IC 50 = 800 nM for Rev-ErbAβ.

Baker identified 3-hydroxy-3-ethylglutarate and 3-hydroxy-3-methylglutarate from the same enzyme source incubated with acetyl and propionyl-CoA. [ 36 ] Lee et al. showed that the same source of enzymes efficiently make both mevalonate and its 3-ethyl homolog, homomevalonate. [ 37 ]
