Insect repellents are important prophylactic tools for travelers and populations living in endemic areas of malaria, dengue, encephalitis, and other vector-borne diseases. DEET (N,N-diethyl-3-methylbenzamide) is a 6-decade-old synthetic repellent, which is still considered the gold standard of mosquito repellents. Mosquitoes

We investigated two-body (binary) and three-body (triple) dissociations of ethanedial, propanal, propenal, n-butane, 1-butene, and 1,3-butadiene on the ground potential-energy surfaces using quantum-chemical and Rice-Ramsperger-Kassel-Marcus calculations; most attention is paid on the triple dissociation mechanisms. The triple dissociation includes elimination

The propensity of site-specific carboxymethylation and propylation of Val-1(α) of Hb to attenuate the reductive hexaPEGylation-induced dissociation of tetramers has been investigated. Only reductive propylation of Val-1(α), which increases the stability of oxy Hb, attenuates the reductive hexaPEGylation-induced dissociation. Increasing

Methylmalonate-semialdehyde dehydrogenase (MSDH) belongs to the CoA-dependent aldehyde dehydrogenase subfamily. It catalyzes the NAD-dependent oxidation of methylmalonate semialdehyde (MMSA) to propionyl-CoA via the acylation and deacylation steps. MSDH is the only member of the aldehyde dehydrogenase superfamily that catalyzes a
