The growth rate and feed efficiency of pigs fed a diet containing 10% dried whey and 20% alfalfa was less than with either treatment alone, suggesting a possible antagonism between alfalfa and whey. A digestibility trial with rats indicated that feeding lactose, a major constituent of whey, reduced the digestibility of alfalfa fiber and purified cellulose. In another rat experiment, the feeding...

In comparison with the original determination based on Weissenberg film data [Khan et al. (1970 ▶). Acta Cryst. B26, 1889-1892], the current redetermination of diammonium hydrogenarsenate(V) reveals all atoms with anisotropic displacement parameters and all H atoms localized. This allowed an unambiguous assignment of the hydrogen-bonding pattern, which is similar to that of the isotypic phospha...

In the title compound, C(3)H(12)N(2) (2+)·2BF(4) (-)·2C(12)H(24)O(6), the central C atom of the propane-1,3-diammonium cation lies on a crystallographic twofold rotation axis. The terminal NH(3) (+) groups insert into the crown rings through strong N-H⋯O hydrogen-bonding inter-actions, resulting in the formation of a 1:2 supra-molecular [(C(3)H(12)N(2))·(C(12)H(24)O(6))(2)](2+) complex. The ani...

5-Methoxysalicylic acid (MSA) is demonstrated to be a useful matrix for matrix-assisted laser desorption/ionization time-of-flight (TOF) mass spectrometry of oligonucleotides, when desorption/ionization without fragmentation is desired. When MSA is combined with the additive spermine, the need for desalting is reduced. The MSA/spermine matrix yields linear TOF mass spectra with improved resolut...

The objective of this study was to characterize the antioxidant properties of ethanol extracted from leaves of Jatropha curcas and to determinate the compounds. The IC50 values of DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt) were found to be 7.47 and 6.6 μg/ml, respectively, for the extracts. The reducing power of the ex...

Diammonium carbonate hydrogen peroxide monosolvate, 2NH(4)(+)·CO(3)(2-)·H(2)O(2), (I), and dicaesium carbonate hydrogen peroxide trisolvate, 2Cs(+)·CO(3)(2-)·3H(2)O(2), (II), were crystallized from 98% hydrogen peroxide. In (I), the carbonate anions and peroxide solvent molecules are arranged on twofold axes. The peroxide molecules act as donors in only two hydrogen bonds with carbonate groups,...

In the redetermined [for the previous study, see Søtofte (1976 ▶). Acta Chem. Scand. Ser. A, 30, 309-311] crystal structure of the title compound, C(2)H(10)N(2) (2+)·2Br(-), the H atoms have been located and the hydrogen-bonding scheme is described. The ethane-1,2-diammonium cation lies over a crystallographic inversion centre and straddles a crystallographic mirror plane with the C and N atoms...
