A Subunit Model for the Tropocollagen Macromolecule.
In this article is presented a novel subunit model for the tropocollagen (TC) macromolecule, the monomeric unit of soluble collagen.1 The TC macromolecule is a rigid rod of definite length composed of three helical polypeptide strands that are equal (or very nearly equal) in length.2 4 The strands are of two types chemically, designated a1 and a2.4 Each macromolecule contains two al strands and...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
The Effects of Proteases on the Tropocollagen Macromolecule and on Its Aggregation Properties.
density distribution has recently been directly demonstrated in electron micrographs of formaldehyde-fixed SIS-type aggregates by Kuhn, K., U. Hofmann, and W. Grassmann (Naturwiss., 46, 512 1959). I For this purpose the segments were stained by exposure to 0.002 M uranyl nitrate for 1 minute and washed with distilled water before drying on the grid. Under these conditions the uranium in solutio...
