Hola, desde hoy en la mañana tengo una duda, ¿de qué material es la "pluma" de los calamares, y el "jibión" de las jibias o sepìas?
Tengo en mi poder una pluma --el único vestigio que queda de la concha en calamares-- pero las conchas son de carbonato de calcio, de nácar, y al menos en los calamares no parece serlo, lo ignoro en las sepias.

¿Saben de qué material está hecho?



La imagen no es mia.



Gracias,

Felipe Torres

Hola Felipe,

La concha interna de la sepia es un jibión o sepión calcáreo (carbonato cálcico) y la del calamar es una pluma córnea, que contiene una gran cantidad de quitina.

La quitina (el segundo polímero natural más abundante después de la celulosa) es uno de los componentes principales de las paredes celulares de los hongos, del resistente exoesqueleto de los artrópodos (arácnidos, crustáceos, insectos) y algunos otros animales.

Es un polisacárido, compuesto de unidades de N-acetilglucosamina unidas entre sí con enlaces β-1,4

Saludos !!
