Anion photoelectron spectra of the carbon monohydrides, C2nH 2 for n51 – 4 and C2nD 2 for n51 – 3, have been measured. The spectra were recorded at a wavelength of 266 nm ~4.657 eV! and yield electron affinities for each species. The spectra are vibrationally resolved, and some of the vibrational modes in the neutral C2nH~D! radicals are assigned. In addition, photoelectron angular distribution...

The nematicidal activity of two cassia, Cinnamomum cassia, oils (Especial and true), four cinnamon, Cinnamomum zey-lanicum, oils (technical, #500, bark and green leaf), and their compounds (e.g., trans-cinnamaldehyde and trans-cinnamic acid) toward adult Bursaphelenchus xylophilus was examined by a direct contact bioassay. Results were compared with those of 34 related compounds. As judged by 2...

El objetivo del estudio fue evaluar el efecto de la adición ácido ascórbico (AA) al medio vitrificación folículos preantrales (FPs) bovinos previamente enfriados a 4 °C durante o 24 h. Se recolectaron ovarios novillas Nelore los 14 meses edad. En laboratorio se extrajeron fragmentos ovario región cortical y distribuyeron para control fresco (C0h), refrigeración ºC por horas en TCM-199 más HEPES...

The "perturbation" effects (i.e. hyperconjugation, electronegativity, and conjugation) on the structural, electronic, and magnetic properties of three kinds of two-dimensional (2D) X-Cr-X (X = C4H, NC3 and BC3 monolayers) sandwich nanostructures were systematically investigated by means of spin-polarized density functional theory (DFT) computations. Although all these 2D sandwich systems energe...

Cinnamic acid and cinnamate derivatives have gained attention due to their potential protective role against oxidative damage diseases, such as coronary heart disease, stroke and cancers. However, their potential interest for the human health goes far beyond their protective antioxidant behaviour. The present review encompasses the involvement of cinnamate and its derivatives against various ch...

BACKGROUND Zinc layered hydroxide (ZLH) intercalated with cinnamate, an anionic form of cinnamic acid (CA), an efficient UVA and UVB absorber, have been synthesized by direct method using zinc oxide (ZnO) and cinnamic acid as the precursor. RESULTS The resulting obtained intercalation compound, ZCA, showed a basal spacing of 23.9 Å as a result of cinnamate intercalated in a bilayer arrangemen...

4-Coumarate:coenzyme A ligase (4CL) plays a key role in phenylpropanoid metabolism, providing precursors for a large variety of important plant secondary metabolites, such as lignin, flavonoids, and phytoalexins. Although 4CLs have been believed to be specific to plants, a gene encoding a 4CL-like enzyme which shows more than 40% identity in amino acid sequence to plant 4CLs was found in the ge...

Particulate and soluble fractions from leaves of Sorghum, Spinacia (spinach), and Coleus, capable of metabolizing l-phenylalanine to cinnamate or to caffeate, are also able to convert l-and d-phenylalanine to phenylacetate. Since cinnamate and phenylacetate are not effectively separated in commonly used chromatographic solvents, some of the isotropic assays used for phenylalanine ammonia-lyase ...

THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND (SYSTEMATIC NAME: 2-amino-1-methyl-4-oxo-4,5-dihydro-1H-imidazol-3-ium 3-phenyl-prop-2-enoate), C(4)H(8)N(3)O(+)·C(9)H(7)O(2) (-), is stabilized by N-H⋯O hydrogen bonding. Cations are linked to anions to form ion pairs with an R(2) (2)(8) ring motif. These ion pairs are connected through a C(2) (2)(6) chain motif extending along the c axis of the unit...
