چکیده
In Wirklichkeit handelt es sich aber nicht um eine einzige Reaktion, vielmehr um einen komplexen Vorgang. Er besteht darin, daß während der Ver brennung ( — 128 kcal) von 180 g Glucose für die Bildung von 1370g lebendiger Zellsubstanz (s.o.) aus Nährstoff chemische und physikalische Arbeit geleistet wird. Dies bedeutet, daß 1 g Trockensub stanz 252 cal entspricht. Dieser Wert ist mit 1 g pro 461 cal Gärungswärme bei anaerober Vermeh rung von Bäckerhefe zu vergleichen.

Release of iron from ferritin by aceto- and benzohydroxamic acids.
The release of iron from ferritin by aceto- and benzohydroxamic acids was studied at two different iron chelator concentrations (100 and 10 mM), at two pH values (7.4 and 5.2), and in the presence or absence of urea. Collectively, the results demonstrate that both aceto- and benzohydroxamic acids remove iron from ferritin. Aceto- and benzohydroxamic acids penetrate the ferritin shell and react ...
متن کاملMutagenicity of hydroxamic acids and the probable involvement of carbamoylation.
A series of hydroxamic acids (aceto-, propiono-, benzo-, and p-nitrobenzo-) and seven derivatives of these were examined for biological activity using Salmonella typhimurium. Acylation to yield O-acetyl and O-benzoyl derivatives markedly enhanced toxic properties and was necessary for mutagenic activity for all but p-nitrobenzohydroxamic acid. The dose necessary to produce a minimum significant...
متن کاملEVALUATION OF ANTIOXIDANT AND ANTIFUNGAL PROPERTIES OF NEW DERIVATIVES OF PERAZOLO [3,4-D]PYRIMIDINE
Background & Aims: Heterocyclic compounds are found be abundant in nature, these compounds have many biological properties, and many drugs also contain heterocyclic rings. In this study, antioxidant and anti-fungal properties of the seven pyrazolo[3,4-d]pyrimidine compounds has been studied that synthesized in Iran and their good antibacterial properties have been reported Materials & Methods:...
متن کاملEffects of penconazole on hormonal crosstalk and fatty acids from salt-stressed safflower
Salinity of soil is a major abiotic stress limiting the crop production and growth of safflower. To mitigate stress, the effects of penconazole (PEN) on the growth of safflower were studied to understand the underlying mechanisms of salt tolerance. PEN, a triazole derivative, which has both fungicidal and plant growth regulator properties, protects plants from several types of abiotic stresses....
متن کاملAnalysis of hydroxamic acids and hydrazides; preparation and properties of dinitrophenyl derivatives of hydroxamic acids, oximes, hydrazides, and hydrazones.
The cleavage of gelatin to smaller molecular units by aqueous hydroxylamine or hydrazine under relatively mild conditions of temperature and pH has suggested the existence of “ester-like” or imide linkages in this protein (1). The amide bonds of gelatin were cleaved only to a minor extent and could not account for the large change in molecular weight. It is known, however, that prolonged treatm...
