(1943) n. Any of several small granular or bead-like resins consisting of two principal parts: a resinous matrix serving as a structural portion, and an ion-active group serving as the functional portion. The functional group may be acidic or basic. Complete deionization of water is ...
In other words, terminal alkenes can be regarded as precursors of methyl ketones, or as masked methyl ketones based on this reaction. This reaction is useful because terminal alkenes are easily available, stable under acidic and basic conditions and inert to nucleophiles. Various terminal alkenes ...
The acidic milieu in the blood may reach a pH of below 7.30 or even below 7.10. The association of enhanced ketone body production and decreased buffering capacity of blood may also lead to ketoacidosis in patients with type 2 diabetes or even in the absence of hyperglycemia, such as during...
The effects of reaction condition, metal loading, acidic and basic properties, pore size and methods of metal loading are investigated. The results show that a balance between the condensation and hydrogenation is necessary for high selectivity of MIBK. Basic sites promote the activity. The ...
(usually VV, MoVI, and/or WVI) and a Lewis acidic cation embedded within a lacunary framework. Building on this concept, an electrophilic pincer-like POM-Pd(ii) hybrid was developed in 2014. A bifunctional substrate containing both a sulfide and an aldehyde moiety was selected as a model ...
The result is increased liver ketone production, leading to abnormally high blood ketones and blood that becomes acidic (hence “acidosis”). Ketoacidosis is very harmful. Ketosis, while also characterized by elevated blood ketones, occurs in the presence of LOW blood glucose. It’s a response ...
and the composition may be solid or liquid; however, when the composition is composed of the ketone-based gas adsorbent and at least one gas adsorbent selected from the group consisting of basic gas adsorbents, sulfur-based gas adsorbents and organic acidic gas adsorbents, the composition is pref...
In terms of the potential applications of HBPs, our research group has been particularly interested in hyperbranched aromatic polymers with acidic functional groups. Such polymers will exhibit acidic functionality in various environments because of their high thermal and chemical stabilities. For instance,...
but does not undergo propeptide removal until after it reaches the secretory granule compartment. Activation is autocatalytic, intramolecular, requires a low pH, and is not calcium dependent;2this late, acidic compartment propeptide removal distinguishes proPC2 activation from that of other...
In acidic or basic media 2 suffers dissociation, while 3 is stable under similar conditions. Electrochemical measurements on dmf solutions of 2 and 3 , along with electrochemical reactions of dtktsc with Zn(OAc) 2 ·2H 2 O and PdCl 2 (CH 3 CN) 2 revealed facile coordination of dtktsc ...
