The effect of alpha-tocopherol on the oxidative cleavage of beta-carotene
(Elsevier B.V., 2000-07-15)
Two cleavage pathways of beta-carotene have been proposed, one by central cleavage and the other by random (excentric) cleavage. The central cleavage pathway involves the metabolism of beta-carotene at the central double ...

Comparative investigation of the cleavage step in the synthesis of model peptide resins: Implications for N-alpha-9-fluorenylmethyloxycarbonyl-solid phase peptide synthesis
(Pharmaceutical Soc Japan, 2007-03-01)
Based on our studies of the stability of model peptide-resin linkage in acid media, we previously proposed a rule for resin selection and a final cleavage protocol applicable to the N-alpha-tert-butyloxycarbonyl (Boc)-peptide ...

S-H bond cleavage in molecules of biological interest with CpFe(dppe)I
(2000)
The reaction of CpFe(dppe)I (Cp, cyclopentadienyl; dppe, Ph2P(CH2)(2)PPh2) with biologically active RSH molecules (L-cysteine hydrochloride, dithiothereitol and 2-mercaptoethanol) in the presence of NH4PF6 and in methanol ...
The zymogen-enteropeptidase system: A practical approach to study the regulation of enzyme activity by proteolytic cleavage
(Amer Soc Biochemistry Molecular Biology Inc, 2004-01-01)
The present research describes an efficient procedure to obtain high levels of trypsinogen and chymotrypsinogen by using a simple, rapid, and easily reproducible method. The extraction process and the time-course of ...

The cathodic cleavage of the nitrobenzoyl group from protected aliphatic amines in N,N-dimethylformamide
(Soc Brasileira Quimica, 1999-05-01)
The electrochemical reduction of aliphatic amines protected by the 4- and 3-nitrobenzoyl group in N,N-dimethylformamide was reported. The compounds are reduced in two cathodic steps. The first one at about -1 V vs. SCE ...
Partisan Cleavages and Changes in Distributive Preferences in Chile
(PONTIFICIA UNIV CATOLICA CHILE, INST CIENCIA POLITICA, 2013)
Beliefs about how goods and resources should be distributed in society constitute a central element in the identification with political parties. In this sense, the preference for a more or less active role of the state ...
Apocarotenoids: A new carotenoid-derived pathway
(Springer New York, 2016)
© Springer International Publishing Switzerland 2016. Carotenoids are precursors of carotenoid derived molecules termed apocarotenoids, which include isoprenoids with important functions in plantenvironment interactions ...
