WebAlkaline hydrolysis allows the partial separation of the cellulose fibres from the cell wall [55, 62, 112 ]. These treatments are usually made using diluted solutions of NaOH (1–10%) at low or high temperatures and of concentrated NaOH solutions at low temperatures. NH 4 OH and anhydrous NH 3 (gas or liquid) are also used to activate the ... Web21 feb. 2010 · Various commercial lyophilized and immobilized preparations of lipase A from Candida antarctica (CAL-A) were studied for their ability to catalyze the hydrolysis of amide bonds in N-acylated alpha-amino acids, 3-butanamidobutanoic acid (beta-amino acid) and its ethyl ester. The activity toward amide bonds is highly untypical of lipases, … WebThe hydrolysis of a peptide bond is helped along by two common means, and those two means are with the help of strong acids or with proteolytic enzymes. So when we use strong acids, we call this acid hydrolysis. And acid hydrolysis, when combined with heat, is a nonspecific way of cleaving peptide bonds. pluralia tantum en russe
