Team finds new way to attach lipids to proteins, streamlining drug development

Protein-based drugs are used in the treatment of every kind of malady, from cancer to heart disease to rheumatoid arthritis. But the proteins are almost always modified with chemical appendages that help them navigate through the body or target specific tissues. A new study reveals an efficient means of attaching lipids (fat molecules) to peptides (the building blocks of proteins). This can improve the molecules' drug-delivery capabilities.
