TSU physicists are investigating the effects of radiation on DNA

Scientists from TSU's Laboratory of Experimental High Energy Physics and their colleagues from the University of Bordeaux are studying new ways of modeling the effects of low doses of radiation at the cellular level. For ...

New method to create ultrafast 3-D images of nanostructures

Lensless microscopy with X-rays, or coherent diffractive imaging, is a promising approach. It allows researchers to analyse complex three-dimensional structures, which frequently exist in nature, from a dynamic perspective. ...

In search of new 'sugar cleavers'

Complex sugars play multiple and essential roles in the living world as structural elements (cellulose), reserve substances (starch), and molecular signals (such as those of blood types), among others. This variety of functions ...

The making of biorelevant nanomaterials

The interactions of biological macromolecules such as nucleic acids, proteins, and polysaccharide–protein conjugates can be mimicked by artificial polyelectrolytes. Such synthetic polyionic complexes are expected to serve ...

In-cell NMR: A new application

The structure of biological macromolecules is critical to understanding their function, mode of interaction and relationship with their neighbours, and how physiological processes are altered by mutations or changes in the ...

Team proposes new law to accurately measure charged macromolecules

For biochemists, measuring the size and diffusion properties of large molecules such as proteins and DNA using dynamic light-scattering techniques and the Stokes-Einstein formula has been mostly straightforward for decades, ...

The PLOS Comp Biol Macromolecular Structure and Dynamics collection

Living systems are in a state of perpetual motion. Down at the microscopic level, the atoms that make up biological macromolecules are, in the words of Richard Feynman, jiggling and wiggling. These atomic motions are beautifully ...

Smart crystallization

A novel nucleating agent that builds on the concept of molecularly imprinted polymers (MIPs) could allow crystallographers access to proteins and other biological macromolecules that are usually reluctant to form crystals. ...

Macromolecule

A macromolecule is a very large molecule commonly created by some form of polymerization. In biochemistry, the term is applied to the four conventional biopolymers (nucleic acids, proteins, carbohydrates, and lipids), as well as non-polymeric molecules with large molecular mass such as macrocycles. The constituent molecules from which macromolecules are assembled are called monomers (mono=single, meros=part).
