Amyloid Fibrils in Brain Disease
Description
Amyloid fibrils are clumps of misfolded proteins linked to brain disease and other disorders. In normal cells, misfolded proteins are usually refolded by chaperone proteins or broken down by the proteasome. But in some mutations or diseases, these proteins can build up into large clusters and then assemble into long fibers c...

Transcript
Le proteine si ripiegano in strutture energeticamente favorevoli con i loro aminoacidi idrofobi all'interno e gli aminoacidi caricati e polari all'esterno. Alcune proteine si ripiegano facilmente da sole, ma molte sono guidate a ripiegarsi correttamente da proteine chiamate chaperones. A volte le proteine si ripiegano in forme errate, spesso ind...
