enlace peptídico
- In protein synthesis, the ribosome creates a peptide bond between the carboxyl group of one amino acid and the amino group of another.
Proteases are enzymes that can hydrolyze the peptide bonds of a polypeptide chain.
- Proteases are enzymes that can hydrolyze the peptide bonds of a polypeptide chain.
Examples
-
So what about peptide bond formation, right.
-
Proteases are enzymes that can hydrolyze the peptide bonds of a polypeptide chain.
-
The large subunit of the ribosome has two strings of RNA, one long and one short; the long string functions as a ribozyme, providing enzyme-like activity that forms the peptide bond between amino acids.
Academic text (2004) -
When amino acids join together, they form a peptide bond that contributes to the protein's overall structure.
-
The enzyme catalyzes the formation of a peptide bond during the translation process.
Synonyms
The chemical bond that joins two amino acids in a protein chain

Morphology
The noun is straightforwardly compositional: 'peptide' (a chain/compound of amino acids) plus 'bond' (a connection between atoms or molecules) yields a connection linking amino acids in peptides or proteins. While the precise chemical detail (carboxyl-to-amino covalent linkage) is specialist knowledge, a B1 learner who knows both constituent meanings can derive the general idea of a chemical link between amino-acid units.
Etymology
Peptide bond is the tiny link that joins two amino acids, like a small clasp between beads on a necklace, and that's why these links keep the long 'chain' of a protein together.
