4-Aminobenzoic acid (also known as para-aminobenzoic acid or PABA because the two functional groups are attached to the benzene ring across from one another in the para position) is an organic compound with the formula H 2 NC 6 H 4 CO 2 H. PABA is a white crystalline solid, [3] although commercial samples can appear gray. It is slightly soluble ...
The folate molecule is synthesized from pterin pyrophosphate, para-aminobenzoic acid (PABA), and glutamate through the action of dihydropteroate synthase and dihydrofolate synthase. Pterin is in turn derived in a series of enzymatically catalyzed steps from guanosine triphosphate (GTP), while PABA is a product of the shikimate pathway .
Bacteriostatic agents such as sulfonamides target dihydropteroate synthetase. The effect of dihydropteroate synthetase inhibition is comparable to that of dihydrofolate reductase inhibition by trimethoprim, another bacteriostatic agent.
Procaine, an ester anesthetic, is metabolized in the plasma by the enzyme pseudocholinesterase through hydrolysis into para-amino benzoic acid (PABA), which is then excreted by the kidneys into the urine. A 1% procaine injection has been recommended for the treatment of extravasation complications associated with venipuncture, steroids, and ...
Padimate O is an organic compound related to the water-soluble compound PABA (4-aminobenzoic acid) that is used as an ingredient in some sunscreens. This yellowish water-insoluble oily liquid is an ester formed by the condensation of 2-ethylhexanol with dimethylaminobenzoic acid. Other names for padimate O include 2-ethylhexyl 4 ...

The Pan Asian Boxing Association, also known as PABA, is an organisation for professional boxing in the Central Asia, Oceania, Pan Pacific, Eurasia and Southeast and Far East nations. It was formed in 1995 and is headquartered in Seoul .
This makes it a useful target for sulfonamide antibiotics, which compete with the PABA precursor. (2-amino-4-hydroxy-7,8-dihydropteridin-6-yl)methyl diphosphate + 4-aminobenzoate (PABA) diphosphate + dihydropteroate. All organisms require reduced folate cofactors for the synthesis of a variety of metabolites.
