The Molecular Structure of Fibrinogen

Seminars in Thrombosis and Hemostasis, 1974
Abstract Seminars in Thrombosis and Hemostasis (STH) celebrates 50 years of publishing in 2024. To celebrate this landmark event, STH is republishing some archival material. This manuscript represents the first full paper ever published in STH.

The Virial and Molecular Structure

The Journal of Chemical Physics, 1933
The virial theorem can be applied to a molecule, assuming that external forces are applied to keep the nuclei fixed. The mean electronic kinetic energy is then the negative of the mean total internal energy, plus a term arising from the virial of the external force.

Wavelets and molecular structure

Journal of Computer-Aided Molecular Design, 1996
The wavelet method offers possibilities for display, editing, and topological comparison of proteins at a user-specified level of detail. Wavelets are a mathematical tool that first found application in signal processing. The multiresolution analysis of a signal via wavelets provides a hierarchical series of "best' lower-resolution approximations.

On the Molecular Structure of Collagen

Nature, 1969
Several polytripeptide and polyhexapeptide models of collagen have the same triple helical conformation with one NH…O interchain H bond per tripeptide. Collagen itself probably has this structure.

The structure of a molecular motor

Current Biology, 1993
Two proteins, actin and myosin, together form a molec- ular motor that produces the work performed by mus- cle tissues, as well as many of the movements seen in all eukaryotic cells. IJntil recently, high resolution struc- tures of these two proteins have not been available.

Chirality Codes and Molecular Structure

Journal of Chemical Information and Computer Sciences, 2004
Some time ago a structure-descriptor, named "chirality code", was put forward [J. Chem. Inf. Comput. Sci. 2001, 41, 369-375], aimed at distinguishing between enantiomers. The chirality code is a sequence of (typically 100) numbers, being equal to the value of a certain "chirality function" at equidistant points within a chosen interval.

The Molecular Structure of Glycogens

1957
Publisher Summary This chapter discusses the molecular structure of glycogens. Glycogens, from vertebrate, invertebrate, bacterial, and yeast cells, are multiply-branched molecules (molecular weight ∼10 7 ) consisting of chains of α-(1 → 4)-linked D-glucose residues.

Molecular Spectra and Molecular Structure

Nature, 1941
DURING the last two decades great progress has been made in the experimental study and theoretical interpretation of molecular spectra, which has thus become one of the most important means we have for investigating molecular structure. There is, indeed, no experimental method that gives more detailed information on this subject.

Molecular shapes and molecular structures

Chemical Physics Letters, 1986
Abstract The first part is a response to E.B. Wilson's remarks about molecular structure at the 1979 Sanibel Symposium; his proposed extension of the notion of “potential energy surface” is a convention, not a part of fundamental molecular quantum theory.

Viscosity and Molecular Structure

Annals of the New York Academy of Sciences, 1951
Publisher Summary This chapter describes the viscosity of molecules and the structure of molecules. Within the framework of a corresponding states system, the viscosity of liquids can be examined most easily if comparisons are confined to specific regions.
