guanidinium
gwan-ih-DIN-ee-um
Definition
A specific chemical group, derived from guanidine, that features a central carbon atom bonded to three nitrogen atoms and is known for its ability to disrupt protective water layers on surfaces.
Etymology
The term is derived from 'guanidine,' which was first synthesized from guano (bird or bat excrement) in the 19th century, combined with the chemical suffix '-ium' used to denote a specific chemical group or ion.
In the news
In the article, the guanidinium group found in the amino acid arginine is identified as the key feature that allows certain proteins to bypass anti-fouling coatings. This is critical because it explains why some proteins adhere to surfaces designed to repel them, which impacts the biocompatibility of medical devices.
