Péptidos y Proteínas
Los péptidos son cadenas cortas de aminoácidos unidas por enlaces peptídicos, mientras que las proteínas son cadenas más largas y complejas de aminoácidos que pueden adoptar estructuras tridimensionales funcionales. Ambos tipos de compuestos son esenciales para diversas funciones biológicas, como la catalización de reacciones (enzimas), la defensa inmunológica (anticuerpos) y la señalización celular. Las proteínas tienen una estructura jerárquica, que incluye la secuencia de aminoácidos, la estructura secundaria, terciaria y cuaternaria. Los péptidos se utilizan en terapias farmacológicas y cosméticas por sus propiedades biológicas específicas, como en el tratamiento de enfermedades metabólicas o la mejora de la regeneración celular. Las proteínas, por su parte, tienen aplicaciones en biotecnología, nutrición y medicina regenerativa.
En CymitQuimica ofrecemos péptidos y proteínas de alta pureza para investigación en biotecnología y aplicaciones terapéuticas.
