Lattice thermal expansion and anisotropic displacements in urea, bromomalonic aldehyde, pentachloropyridine and naphthalene [PDF]
The Journal of Chemical Physics 147, 074112 (2017), 2017 Anisotropic displacement parameters (ADPs) are commonly used in crystallography, chemistry and related fields to describe and quantify thermal motion of atoms. Within the very recent years, these ADPs have become predictable by lattice dynamics in combination with first-principles theory.

Toward the limits of complexity of interstellar chemistry: Rotational spectroscopy and astronomical search for n- and i-butanal [PDF]
A&A 666, A114 (2022), 2022 In recent times, large organic molecules of exceptional complexity have been found in diverse regions of the interstellar medium. In this context, we aim to provide accurate frequencies of the ground vibrational state of two key aliphatic aldehydes, n-butanal and its branched-chain isomer, i-butanal, to enable their eventual detection in the ...

Microbial Engineering for Aldehyde Synthesis [PDF]
Applied and Environmental Microbiology, 2015 Aldehydes are a class of chemicals with many industrial uses. Several aldehydes are responsible for flavors and fragrances present in plants, but aldehydes are not known to accumulate in most natural microorganisms. In many cases, microbial production of

Is there any linkage between interstellar aldehyde and alcohol? [PDF]
, 2021 It is speculated that there might be some linkage between interstellar aldehydes and their corresponding alcohols. Here, an observational study and astrochemical modeling are coupled together to illustrate the connection between them. The ALMA Cycle 4 data of a hot molecular core, G10.47+0.03 is utilized for this study. Various aldehydes (acetaldehyde,

Functionalisation of Artemisinin and Its Ring-contracted Derivatives
Molecules, 2007 Isoxazoline analogues of artemisinin were obtained in low yield and low diastereoselectivity from the 1,3-dipolar cycloaddition of nitrile oxides. Alternatively, starting from the aldehyde 7, a number of transformations - Wittig reaction and reduction ...

Stereospecificity of cinnamyl alcohol dehydrogenase and synthesis of stereospecifically labelled coniferyl alcohol [PDF]
, 1978 Using horse liver alcohol dehydrogenase, stereospecifically tritiated (R)- and (S)-(γ-3H)-coniferyl alcohol was synthesized. Using both of these substrates it was demonstrated that cinnamyl alcohol dehydrogenase from lignifying Forsythia tissue ...

The olfactory basis of orchid pollination by mosquitoes. [PDF]
, 2020 Mosquitoes are important vectors of disease and require sources of carbohydrates for reproduction and survival. Unlike host-related behaviors of mosquitoes, comparatively less is understood about the mechanisms involved in nectar-feeding decisions, or ...

(Sub-)millimeter-wave spectroscopy of gauche-propanal [PDF]
J. Mol. Spectrosc. 384 (2022) Art. No. 111565, 2021 A detailed analysis of (sub-)millimeter-wave spectra of the vibrational ground state ($\upsilon=0$) combined with the energetically lowest excited vibrational state ($\upsilon_{24}=1$; aldehyde torsion) of gauche-propanal (g-C$_2$H$_5$CHO) up to 500 GHz is presented.

Formation of a Flavin-Linked Peptide
Molecules, 2014 In a previous study, we showed that formylmethylflavin (FMF) can bind to cysteine. In this study, FMF was reacted with native peptides (CG and CKLVFF) containing an N-terminal cysteine.
