Because it targets fatty molecules in the cell wall instead of proteins it is also much less likely than most antibiotics to induce microbial resistance.
Although the intentional infiltration of chemicals into cell walls has long been studied, the transfer of specific components from adhesives into cell walls has not been widely appreciated.

For decades researchers had searched for peptidoglycan--a mesh-like polymer that forms the cell wall in diverse bacteria--in the bacterial pathogen Chlamydiae peptidoglycan in hopes of studying its structure and synthesis as a path to drug development against a class of bacteria responsible for one in 10 cases of pneumonia in children, as well as more than 21,000,000 cases of the blindness-causing disease trachoma.
This indicates that, while alkamides and CAS both sensitize yeast cell walls to sonication-induced breakage, the alkamides likely have a different mode of action from CAS.

The cell walls form the structural supports of all plants.
This should, however, lead to fringy edges of the holes in the cell walls as opposed to smooth edges when fracture occurs during foaming.
Depending on how the cell walls are arranged, and what they are made of, a plant can be as flimsy as a reed or as sturdy as an oak, said Lorna Gibson, a professor of materials science and engineering at the Cambridge, Mass.
Like wooden beams reinforcing a house, cell walls make up the structural supports of all plants.
