Question 9 of 11 Map d Sapling Learning this question was written by Matt Cordes at University of Arizona Which of the following are true statements about the amyloid beta peptide? Select all that apply. Note that beta peptide aggregation may share some but not all features of other amyloid-forming proteins peptides. Individual subunits (polypeptide chains) associate with each other by forming antiparallel beta-sheet structures The beta-strands are oriented parallel to the long axis of the fiber or protofilament. Each subunit contributes two beta-strands to the fibril structure When part of the amyloid precursor protein, it spans a membrane and forms alpha-helical secondary structure A major part of what stabilizes the aggregate is the fact that identical glutamine and asparagine side chains in adjacent subunits can make hydrogen with each otherExplanation / Answer
Option 1 individual subunits associate with each other by forming antiparallel beta sheets.
Option 4 when part of the amyloid precursor protein Spencer membrane and forms Alpha helical secondary structure
Option 5 a major part of what stablizers the aggregate is the fact that identical glutamine and asparagine side chains in adjacent subunits can make hydrogen bonds with each othera
