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...
متن کاملNew complexes of peroxidases with hydroxamic acids, hydrazides, and amides.
Horseradish peroxidase forms spectroscopically distinct, reversible complexes with hydroxamic acids (R-CONHOH), hydrazides (RCO-NHNH2), amides (RCONH2), and oc-hydroxyketones (RCO--CHsOH). Binding of these compounds to the enzyme depends on the polar and steric character of R and the hydrogen bonding capacity of-COX-Y (X-Y = NH-OH, NH-NH,, NH-H, CH,OH). Hydroxamate anions and hydrazide cations ...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
