NMR spectroscopy of Cu(II) complexes with acrylamide and sodium acrylate copolymer and ω-amino acids

open access: yesЖурнал Белорусского государственного университета: Химия, 2021
Macromolecular complexes of acrylamide and sodium acrylate copolymer with microelements, including Cu(II), may form at preparation of crop protection and stimulation compositions, where the copolymer serves as an adhesive, water-retaining and film ...

Carboxylic acids - snapshot

open access: yes, 2022
A carboxylic acid is an organic acid that contains a carboxyl group (C(=O)OH) attached to an R-group. The general formula of a carboxylic acid is R−COOH or R−CO2H, with R referring to the alkyl, alkenyl, aryl, or other group.

The effect of aliphatic carboxylic acids on olfaction-based host-seeking of the malaria mosquito Anopheles gambiae sensu stricto [PDF]

open access: yes, 2009
The role of aliphatic carboxylic acids in host-seeking response of the malaria mosquito Anopheles gambiae sensu stricto was examined both in a dual-choice olfactometer and with indoor traps.

Carboxylic acids and light interact to affect nanoceria stability and dissolution in acidic aqueous environments

open access: yesBeilstein Journal of Nanotechnology, 2023
Cerium atoms on the surfaces of nanoceria (i.e., cerium oxide in the form of nanoparticles) can store or release oxygen, cycling between Ce3+ and Ce4+; therefore, they can cause or relieve oxidative stress within living systems.

Direct Boronic Acid Promoted Amidation of Carboxylic Acids with Poorly Nucleophilic Amines [PDF]

open access: yes, 2022
Direct amidation of carboxylic acids with poorly nucleophilic amines such as anilines is a notorious challenge in organic chemistry. Previously reported methodologies for direct amidation tend to report none or just a few examples with simple anilines ...

Using pyrimidinecarboxylic acids as growth stimulants for Rhododendron ledebourii Pojark and Rhododendron smirnowii Trautv.

open access: yesActa Agriculturae Slovenica, 2023
Synthesised organic compounds of pyrimidinecarboxylic acids are characterised by high biological activity, even when their concentrations are low. These compounds, when applied to the seeds of Rhododendron, a genus of woody plants, with concentrations of

Oligomerization of Indole Derivatives with Incorporation of Thiols

open access: yesMolecules, 2008
: Two molecules of indole derivative, e.g. indole-5-carboxylic acid, reacted with one molecule of thiol, e.g. 1,2-ethanedithiol, in the presence of trifluoroacetic acid to yield adducts such as 3-[2-(2-amino-5-carboxyphenyl)-1-(2-mercaptoethylthio)ethyl]-

Study on differential expression of 1-aminocyclopropane-1-carboxylic acid oxidase genes in table grape cv. Thompson Seedless [PDF]

open access: yes, 2013
As a consequence of the non-climacteric status of grapes (Vitis vinifera), ethylene biosynthesis and signal transduction have scarcely been studied in this fruit.

Indole-3-carboxylic acid [PDF]

open access: yes, 2003
The crystal structure of indole-3-carboxylic acid, C9H7NO2, shows the presence of centrosymmetric hydrogen-bonded cyclic carboxylic acid dimers [OO = 2.649 (2) ŝ. These dimers are linked into a sheet structure through peripheral intermolecular hydrogen
