Peptides are biomolecules formed ... such as Alzheimer's and Parkinson's, since after chemical modification the molecule acquires an amyloidal structure, which favors aggregation of molecules ...

Centromeres, specialized regions located at the center of chromosomes, are critical for ensuring proper cell division. During ...

The central dogma of molecular biology is that the one-dimensional ... fold into the complex three-dimensional (3D) protein structures that have been solved at great expense experimentally.

In 1963, Stein, Moore and Hirs published the entire amino acid sequence for ribonuclease A — the first description of an enzyme's chemical structure and the largest protein decoded at that time. Stein ...

Proteins are among the most studied molecules in biology, yet new research shows they can still hold surprising secrets. Researchers have discovered previously undetected chemical bonds within ...

In a paper published recently in ACS Nano, Lew and colleagues outline how they used the Nile red chemical probe ... visualize the fiber structures formed by synthetic peptides and by amyloid ...

For most proteins, structure is function. The complex three-dimensional shapes that proteins adopt create folds and pockets that can accomplish the remarkably improbable: driving chemical ...

Most of those 20 have distinctive chemical properties ... into a complex three-dimensional structure. That structure is essential for the protein's function. Typically, figuring out the structure ...

Centromeres, specialized regions located at the center of chromosomes, are critical for ensuring proper cell division. During mitosis, centromeres ...

Through simulations and detailed analyses of the physical forces and chemical interactions involved ... study investigating the divergent structure of protein-regulated multiphase condensates ...
