Peptides et Protéines
Les peptides sont de courtes chaînes d'acides aminés reliées par des liaisons peptidiques, tandis que les protéines sont des chaînes d'acides aminés plus longues et complexes pouvant adopter des structures tridimensionnelles fonctionnelles. Ces deux types de composés sont essentiels à diverses fonctions biologiques, comme la catalyse des réactions (enzymes), la défense immunitaire (anticorps) et la signalisation cellulaire. Les protéines ont une structure hiérarchique comprenant la séquence d’acides aminés, ainsi que les structures secondaire, tertiaire et quaternaire. Les peptides sont utilisés dans les thérapies pharmaceutiques et cosmétiques pour leurs propriétés biologiques spécifiques, notamment dans le traitement des maladies métaboliques ou l’amélioration de la régénération cellulaire. Les protéines, quant à elles, ont des applications en biotechnologie, en nutrition et en médecine régénérative.
Chez CymitQuimica, nous proposons des peptides et des protéines de haute pureté pour la recherche en biotechnologie et les applications thérapeutiques.

<p>Desmopressin is a synthetic drug that is used to treat diabetes insipidus and bleeding in patients who are on anticoagulants. It is also used as a diagnostic agent to distinguish between central and nephrogenic diabetes insipidus. Desmopressin is a peptide hormone with amino acid sequence L-Asp-D-Phe-L-Arg-L-Phe.
