Question
Chapter 10, Problem 10.29PP
Summary Introduction
To explain:
The difference in the secondary structure present in the beta-amyloid protein in a normal person and a person with Alzheimer’s disease.
Introduction:
Alzheimer’s disease is caused due to the formation of plaques of beta-amyloid protein which accumulates in the neurons. This causes loss of memory and dementia in old age. It interferes with the generation of action potential and the transmission of signals in brain.
