Nearly all bacteria contain peptidoglycan. Review the structure of peptidoglycan by selecting the correct characteristics listed below.
Check All That Apply
Polymer of alternating N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM)
Contains a tetrapeptide that extends from N-acetylglucosamine (NAG)
Contains D-amino acids not found in proteins
All bacteria use a peptide interbridge to connect the sugar strands
Peptidoglycan is a strong and rigid structure
Which statement best describes the protein structure shown below?
This is an alpha helix.
This is a tertiary structure that consists almost entirely of beta strands.
This is a tertiary structure consisting of a roughly equal mixture of alpha helices and beta sheets.
This is a beta sheet.
This is a tertiary structure that consists almost entirely of alpha helices.
Draw a parallel beta sheet and an antiparallel beta sheet (three strands each). Show the
hydrogen bonding pattern as well as the positions of the R groups of the amino acids. You do not
need to draw the exact atoms; a simple representation is fine.
