Proteins and peptides are the primary functional polymers of medical biochemistry, directing virtually all cellular processes through their structural diversity, catalytic activities and signalling ...

How did life originate? Ancient proteins may hold important clues. Every organism on Earth is made up of proteins. Although all organisms—even single-celled ones—have complex protein structures now, ...

Researchers had not yet identified ways in which they might affect biochemistry far from their physical structures. Now, in a new study published September 10 in the journal Cell, researchers from ...

The genetic code has given rise to the enormous diversity of proteins we see in nature—and rearranging the order of codons that make up a protein’s sequence leads to an immense variety of structure ...

Sometimes, life can be a real drag—especially if you’re a protein weighed down by unwanted baggage. Researchers have unveiled evidence that these ponderous proteins could be involved in a range of ...

Biochemistry and cell biology together address how molecules assemble into living cells, how cells sustain life through chemical reactions and how they organise into tissues and organs. Biochemistry ...

Amyloids are perhaps best known as a key driver of Alzheimer’s disease. The amorphous proteins, found throughout the human body, stick to nerve cells like plaque, choking off their function and ...
