... miotherma, a thermophilic bacterium of the order Thermotogales, accumulates α-glutamate at the highest salinity tolerated but accumulates only small amounts of this amino acid at low salinities [17]. On the other hand, the closely related species P. mobilis accumulates not only α-glutamate but also ...

The DH% obtained was higher with protease XIV using collagen from fins (28.1±2.2) and arms (22.3±3.3), compared with hydrolysates obtained with trypsin using collagen from fins (24±2.8) and arms (15.4±2.2). Although the bioactivity of proteins may be increased by hydrolysis with specific enzymes, pr ...

Peptide synthesis

In organic chemistry, peptide synthesis is the production of peptides, which are organic compounds in which multiple amino acids are linked via amide bonds, also known as peptide bonds. The biological process of producing long peptides (proteins) is known as protein biosynthesis.
