Phenylalanine bonds
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. Web7. jan 2024 · The present study reports a novel L-phenylalanine monohydrate (L-Phe·H 2 O) soft crystal, which has the potential to be developed as a medical microdevice owing to its flexibility and biosafety. Structure analysis indicated that there were plenty of directional hydrogen bonds distributed along almost every direction of the L-Phe·H 2 O crystal, which …
