Gamma-Guanidinobutyric acid (4-GBA) is used to study intestinal transport by the human proton-coupled amino acid transporter(s) (hPAT1). 4-GBA is used with other model compounds such as 1,6-diaminohexane, 1,6-diguanidinohexane, and 1,6-di(cyanoguanidino)hexane to study the biodegradability of the biocide polyhexamethylene biguanide (PHMB).
ChEBI: 4-guanidinobutanoic acid is the 4-guanidino derivative of butanoic acid. It has a role as a fungal metabolite, a Saccharomyces cerevisiae metabolite and a mouse metabolite. It is functionally related to a butyric acid. It is a conjugate acid of a 4-guanidinobutanoate. It is a tautomer of a 4-guanidinobutanoic acid zwitterion.
