Peptidi e Proteine
I peptidi sono corte catene di amminoacidi legate da legami peptidici, mentre le proteine sono catene di amminoacidi più lunghe e complesse, capaci di assumere strutture tridimensionali funzionali. Entrambi i tipi di composti sono essenziali per diverse funzioni biologiche, come la catalisi delle reazioni (enzimi), la difesa immunitaria (anticorpi) e la segnalazione cellulare. Le proteine hanno una struttura gerarchica che comprende la sequenza di amminoacidi e le strutture secondaria, terziaria e quaternaria. I peptidi vengono utilizzati in terapie farmaceutiche e cosmetiche per le loro specifiche proprietà biologiche, ad esempio nel trattamento di malattie metaboliche o nel miglioramento della rigenerazione cellulare. Le proteine, invece, trovano applicazioni in biotecnologia, nutrizione e medicina rigenerativa.
Presso CymitQuimica, offriamo peptidi e proteine di alta purezza per la ricerca in biotecnologia e applicazioni terapeutiche.
