Interaction of Cartilage Biopolymers
Section on Tissue Biophysics and Biomimetics, NICHD, National Institutes of Health, 13 South Drive, Bethesda, MD 20892, USA E-mail: [email protected] Summary: Aggrecan is a charged biopolymer whose complexes with hyaluronic acid provide the compressive resistance of cartilage. In cartilage extracellular matrix aggrecan-hyaluronic acid complexes are enmeshed within a network of collagen fibr...
متن کاملConformations of confined biopolymers.
Nanoscale and microscale confinement of biopolymers naturally occurs in cells and has been recently achieved in artificial structures designed for nanotechnological applications. Here, we present an extensive theoretical investigation of the conformations and shape of a biopolymer with varying stiffness confined to a narrow channel. Combining scaling arguments, analytical calculations, and Mont...
متن کاملOptical Microrheology of Biopolymers
We use passive and active techniques to study microrheology of a biopolymer solution. The passive technique is video tracking of tracer particles in the biopolymer, a technique which is well established. The active technique is based on rotating optical tweezers, which is used to study viscosity. A method to actively measure viscoelascity using time varying rotation of a particle trapped in opt...
متن کاملSequence-structure relations of biopolymers
Motivation DNA data is transcribed into single-stranded RNA, which folds into specific molecular structures. In this paper we pose the question to what extent sequence- and structure-information correlate. We view this correlation as structural semantics of sequence data that allows for a different interpretation than conventional sequence alignment. Structural semantics could enable us to iden...
متن کاملDiscrete Models of Biopolymers 2
Discretized models of biopolymer structures can be used not only as approximations of the actual spatial structures but also as a computationally feasible approach to the generic features of the sequence-structure relationships. We review the combi-natorics of nucleic acid secondary structures as well as lattice models of proteins, and show how properties such as the existence of extended neutr...
