Peptidien
Peptidien is a term used in some languages to refer to peptides, which are short chains of amino acids linked by peptide bonds. In many contexts, Peptidien is essentially synonymous with peptide, though English usage typically prefers the term peptide for these molecules. Peptidien can describe dipeptides, tripeptides, and longer oligopeptides, including polypeptides when the chain is long.
Chemistry and structure: Each amino acid residue is joined to the next by a covalent peptide bond
Biosynthesis and occurrence: In biology, most peptides are produced as parts of larger proteins by ribosomes
Functions and examples: Peptides serve as hormones (such as oxytocin and vasopressin), neurotransmitters, signaling molecules, or
Analysis and applications: Peptides are routinely analyzed by mass spectrometry and chromatography. They are synthesized for
