Amyloid
Amyloid
Amyloid (/ˈæmɪˌlɔɪd/, from Greek: ἀμυλοειδής, amyloides, "starch-like"), is a type of protein that can fold into a shape that allows many copies of that protein to stick together, forming fibrils.
Etymology
The term "amyloid" was coined by Rudolf Virchow, a German pathologist, in 1854. He used the term to describe deposits in tissues that had a waxy, starch-like appearance when treated with iodine and sulfuric acid. The term is derived from the Greek words "amylon" which means starch and "eidos" which means like.
Pronunciation
The term "Amyloid" is pronounced as "am-uh-loid".
