    Notes: [Auszug] It is known from work on many different types of cells that the mitochondrial ATP is rapidly turned over ; but it is not known if the same holds for the ATP in the chromaffin granules. Either the main function of the ATP is to act here as the anion that holds the catechol bases in the storage ...

    Notes: [Auszug] IT is perhaps ungenerous to complain that the title of this book is wider than the contents, when the author himself has admitted this in his introduction and made his excuses. The book is, in fact, mainly about the properties of acids and bases, or at least about the transfer of protons from one ...

    Notes: [Auszug] The close structural relationship between this 'queen substance' and 'royal jelly acid', 10-hydroxy-dec-2-enoic, found abundantly in royal jelly, would lead one to assume that the latter is a precursor of the former. Moreover, it would seem reasonable to predict that 9-hydroxydec-2-enoic acid might ...

    Notes: [Auszug] During one experiment, a chance contaminant colony of Penicillium sp. was found to grow on a plate of unsupplemented nutrient agar on which colonies of an unstable strain (D) produced by treatment with HN-2 were giving rise to yellow sectors. Around the contaminant colony, colonies of strain D did ...

    Notes: [Auszug] An ion exchanger containing a complexing metal ion (Cu2+, Cu+, Ni2+, Ag+, Cos+, etc.) is used as a solid sorbent. The potential ligands are sorbed from solutions or gases and form complexes with the metal in the resin or displace other ligands which have previously complexed the metal. The latter ...
