Abstract:
Synthetic VGGVG, a "monomeric" unit of the glycine-rich regions of elastin, has been investigated for its molecular and supramolecular properties. In aqueous solution the pentapeptide showed conformational features strongly concentration-dependent. CD and NMR studies suggested a partial unfolding on increasing the concentration. Electron microscopy, on the other hand, evidenced extensive aggregation of the pentapeptide yielding elastin-like supramolecular structures constituted either by twisted ropes or by banded fibrils.

The Extracellular Matrix
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...
