Enzymatic studies with 3-oxa n-3 DPA

Short term DPA ( 22 : 5 n - 3 ) supplementation increases tissue DPA , DHA and EPA 1 concentration in rats

49 50 The metabolic fate of dietary n-3 docosapentaenoic acid (DPA) in mammals is currently 51 unknown. The aim of this study was to determine the extent of conversion of dietary 52 DPA to docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) in rats. Four 53 groups of male weanling Sprague Dawley rats (aged 5 weeks) were given 50 mg of 54 DPA, EPA, DHA or oleic acid, daily for 7 days by g...

Inhibition of Neutrophil Leukotriene B4 Production by a Novel Synthetic N-3 Polyunsaturated Fatty Acid Analogue, -Oxa 21:3n-3

N-(3-Chloro­phen­yl)-N′-(3-methyl­phen­yl)succinamide

The asymmetric unit of the title compound, C(17)H(17)ClN(2)O(2), contains one half-mol-ecule with a center of inversion at the mid-point of the central C-C bond. The amide N-H group is anti to the meta-chloro/methyl groups in the adjacent benzene rings. The dihedral angle between the benzene ring and the NH-C(O)-CH(2) segment is 43.5 (1)°. In the crystal, inter-molecular N-H⋯O hydrogen bonds li...

N-(3-Chloro­benzo­yl)-3-nitro­benzene­sulfonamide

In the title compound, C(13)H(9)ClN(2)O(5)S, the dihedral angle between the two benzene rings is 83.5 (1)°. In the crystal, mol-ecules are linked via N-H⋯O(S) hydrogen bonds into helical chains running along the b axis.

Coxeter n - polytopes with n + 3 facets

We use methods of combinatorics of polytopes together with geometrical and computational ones to obtain the complete list of compact hyperbolic Coxeter n-polytopes with n + 3 facets, 4 ≤ n ≤ 7. Combined with results of Esselmann [E1] this gives the classification of all compact hyperbolic Coxeter n-polytopes with n + 3 facets, n ≥ 4. Polytopes in dimensions 2 and 3 were classified by Poincaré [...
