Question
Chapter 10.1, Problem 3CC
Summary Introduction
To determine: The outcome when an unstretched elastic fiber, treated with a chemical to break the crosslinks between adjacent elastin proteins, was stretched.
Introduction: The proteins present in the extracellular matrix (ECM) are categorized into adhesive proteins and structural proteins. Collagen and elastin comprise the structural proteins, which provide the ECM its strength and elasticity.

O intermediate filaments are not directional. * Previousarrow_forwardNeurofilament proteins assemble into long, intermediate filaments , found in abundance running along the length of nerve cell axons. The C-terminal region of these proteins is an unstructured polypeptide, hundreds of amino acids long and heavily modified by the addition of phosphate groups. The term “polymer brush” has been applied to this part of the neurofilament. can you suggest why?arrow_forward
