In living organisms, every protein—a type of biological polymer consisting of hundreds of amino acids—carries out specific ...

The macromolecular organization of photosynthetic complexes within the thylakoids of higher plant chloroplasts has been a topic of significant debate. Using in situ cryo-electron tomography, this ...

Dysfunctional Family. A family tree of tau folds now incorporates two new structures—P301L, P301T (bottom)—and fills in ...

Proteins are biopolymers of amino acids (polypeptides), joined by peptide bonds, that are generated by ribosomes. The amino acid sequence, encoded by its gene, determines a protein’s structure ...

Protein folding is the process by which proteins achieve their mature functional (native) tertiary structure, and often begins co-translationally. Protein folding requires chaperones and often ...

Foods high in protein represent a variety of options, with many food choices in the meat, poultry, fish, beans, nuts, whole grains, dairy, and soy categories. Fruits and vegetables play a small but ...

Barber completed her PhD in physics at Washington State University with a focus in astrophysics, studying globular cluster systems. Before working at NPR, she taught physics and astronomy at ...
