Microsomes of the yeast, Hansenula ciferri NRRL Y-1031, F-60-10, contain an enzyme (long chain base-acetyl coenzyme A acetyltransferase, EC 2.3 . 1) which catalyzes the transfer of the acetyl moiety of acetyl coenzyme A to both the amino and hydroxyl groups of the sphingosine bases; a separation of these two transfer reactions could not be achieved. The enzyme also catalyzed an acetyl transfer ...

The asymmetric unit of the title compound, (C(23)H(33)N(2))[Li(C(32)H(16)N(8))]·0.5C(3)H(6)O·H(2)O, consists of two symmetry-unrelated lithium phthalocyanine (LiPc(-)) half-anions, centered at (1,0,0) and (0,,0), respectively, the bis-(adamant-yl)imidazolium cation (BAI(+)), occupying a general site, an acetone mol-ecule, disordered about the inversion centre at (0, , ) and a water mol-ecule at...

the chemistry of 2-oxo-1,2,3,4-tetrahydropyrimidines began to develop toward the end of 1893 year, when the first representatives of this class compounds were reported by p. biginelli. despite prior reports of several really effective catalytic and non-catalytic approaches towards biginelli-type products, an overwhelming number of new catalysts for the biginelli reaction have been recently publ...

Continuous control of blood glucose levels is important for the effective treatment diabetes. The short-term use enzymatic continuous monitoring systems involves expensive maintenance and inconvenient, which limits their widespread by diabetes patients. fluorescent diboronic anthracene-embedded system has demonstrated in vivo 12 times longer than protecting dye from reactive oxygen species. How...
