The three-dimensional structure adopted by biological macromolecules largely determines their role in different cellular processes. Several different imaging techniques ranging from X-ray ...

Water, organic molecules, and inorganic ions are the constituents of cells. Water constitutes the greatest fraction of the three, accounting for almost three-quarters of the total mass of a cell. The ...

Note that the brush molecules in Fig. 1b,d have the same chemical composition as their linear counterparts in Fig. 1a,c, although showing the very distinct mixing behaviour. Apparently, the hairy ...

Macromolecules comprise a growing group of new pharmaceutical products with the potential to treat diseases that heretofore have had no effective therapeutic options. To date, the therapeutic ...

In a discovery with wide-ranging implications, researchers recently announced that uniformly charged macromolecules -- or molecules, such as proteins or DNA, that contain a large number of atoms all ...

The human skin protects the body from physical, mechanical, and chemical insults while preventing endogenous water loss. This function is predominantly achieved by a thin (10–30 µm) cornified ...

Understanding the molecular mechanisms underlying the phenomenon of photosynthesis can enable significant progress in the fields of biotechnology and renewable energy. Photosystem II (PSII), a protein ...

Chemists at the Department of Energy’s Oak Ridge National Laboratory have developed a method for producing new macromolecules with improved properties by modifying the polymers in discarded plastics.

In order for life to emerge both peptides and nucleic acids must have appeared under “prebiotic” conditions. Despite numerous efforts, the formation of these macromolecules without the help of modern ...
