daily, organophosphorus compounds (ops) in human life, has found wide applications. although ops have biodegradability potential, they induce clinical problems in humans and other organism. different methods are used to detoxify these compounds. in the meantime, biodegradation is preferred as a compatible way to the environment since it produces less toxic compounds. enzymes capable to degrade ...

cow’s milk whey consists of many protein components and some of them are antigens to human and known to modulate immune responses. enzymatic hydrolysis is a useful method to modify proteins with allergenicity. the objective of this study was to identify whether the in vitro enzymatic hydrolysis could reduce the allergenicity of whey protein concentrates (wpc). in  this study, wpc were hydrolyze...

The theory of elastic group transfer for the binding and release rate constants for nucleotides in F1-ATPase as a function of the rotor angle is further extended in several respects. (i) A method is described for predicting the experimentally observed lifetime distribution of long binding events in the controlled rotation experiments by taking into account the hydrolysis and synthesis reactions...

Observations with acetylcholinesterase can be well explained by postulating that the active site contains two subsites: one, an anionic site which binds and orients substituted ammonium ions, and the other, an esteratic site where the hydrolytic process occurs and which contains a basic group which is acetylated and deacetylated during the process (4, 5). The formation of an acetyl enzyme sugge...

In order to protect the environment and cellulose resources, yarn wastes from textile industry, which contains a considerable amount of cellulose, can be used produce microcrystalline cellulose. this study, waste was milled via ball mill subjected acid hydrolysis using sulfuric hydrochloric at different times. It characterized through various tests determine particle size, degree polymerization...

Freeze dried protein powders (Fresh minced meat, FMM and Hot water dip, HWD) from tilapia (Oreochromis niloticus) were hydrolyzed by Alcalase 2.4 L (Alc), Flavourzyme (Flav) and Neutrase (Neut), and investigated for antioxidant activity and their functional properties. FMM and HWD hydrolysed by Alc, exhibiting superior antioxidant activity, had estimated degrees of hydrolysis (DH) of 23.40% and...

Total lipid and phospholipid recovery as well as amino acid quality and composition from cuttlefish (Sepia officinalis) and sardine (Sardina pilchardus) were compared. Enzymatic hydrolyses were performed using the three proteases Protamex, Alcalase, and Flavourzyme by the pH-stat method (24 h, pH 8, 50 degrees C). Three fractions were generated: an insoluble sludge, a soluble aqueous phase, and...

Neutrase 0.8L and N120P proteases were used for oligopeptide production from apricot almonds meal, and response surface design was carried out to optimize the effect of hydrolysis conditions on hydrolysis degree (DH) and oligopeptide yield rate. Four independent variables were used to optimize the hydrolysis process: hydrolysis temperature (X(1)), enzyme-to substrate ratio (E/S) (X(2)), substra...

The function of bacteria in the production of ammonia from the protein substances in soil is well known. How these proteins are acted upon, whether it is a hydrolytic process brought about by enzymatic action, whether an oxidative one, or whether a more complex chemical reaction, is yet an unsettled question. In order to ascertain, if possible, by controlling influencing factors as much as cond...
