New triazine-based tricarboxylic acid linkers were prepared as elongated relatives of triazinetribenzoic acid (TATB). Additionally, functional groups (NO2, NH2, OMe, OH) were introduced for potential post-synthetic modification (PSM) of MOFs. Functionalized tris(4-bromoaryl)triazine "cores" (3a,3b) were obtained by unsymmetric trimerization mixing one equivalent of an acid chloride (OMe or NO2 ...

The genus BaciUus is one of the few remaining important groups of bacteria for which a route of terminal oxidation has not been shown. In studies (Gary et al., 1954) on the effect of nutrition on metabolic patterns in Bacilus subtilis, it was suggested that cells grown in a glucose mineral salts medium probably possefs the enzymatic mechanisms of the tricarboxylic acid cycle. Hardwick and Foste...

Controlling the ratio of 2,2'-bpy to benzene-1,3,5-tricarboxylic acid produces two interesting complexes, namely [Co(2,2'-bpy)₃]·(SO₄)·8.5H₂O (1) and [Cu₂(BTCA) (2,2'-bpy)₄] (OH)·(2,2'-bpy)₀.₅·14H₂O (2) (H₃BTCA = benzene-1,3,5-tricarboxylic acid, 2,2'-bpy = 2,2'-bipyridine). We report the structural evidence in the solid state of discrete lamellar water cluster conformations. These units are fo...

Nanomaterial of Cu(3)(BTC)(2) (BTC = benzene tricarboxylic acid) incorporating Keggin heteropolyacid conveniently prepared at room temperature and recovered by freeze drying outperforms ultrastable Y zeolite in acid catalysed esterification reaction.

Resolution of a tricarboxylic acid derived from a chiral tris(dipyrrinato)cobalt(III) complex provides a series of enantiopure metallotectons that crystallise as porous hydrogen-bonded networks.

1. The activities of 2-oxoglutarate dehydrogenase (EC 1.2.4.2) were measured in hearts and mammary glands of rats, mice, rabbits, guinea pigs, cows, sheep, goats and in the flight muscles of several Hymenoptera. 2. The activity of 2-oxoglutarate dehydrogenase was similar to the maximum flux through the tricarboxylic acid cycle in vivo. Therefore measuring the activity of this enzyme may provide...
