The farnesoid X receptor (FXR) is a bile acid nuclear receptor that plays a crucial role in regulating bile acid and sterol metabolism.

Proteins are built by mixing and matching amino acids, but researchers want to create new functions ... and produced more than 100 new cyclic peptides, each containing up to three ncAAs. “[The study] ...

Peptides are amino acid polymers. They are generally much smaller ... encoded libraries enable the rapid exploration of new cyclic peptide topologies. Living systems create exceptional materials ...
