ChEBI: A mercaptopropanoic acid that is propanoic acid carrying a sulfanyl group at position 3. | [General Description]
3-Mercaptopropionic acid (3-MPA) is used as a self-assembled monolayer (SAM) with a thiol and carboxylic groups. It has short carbon chains and is mainly used as a capping agent on a variety of nanoparticles. | [Biological Activity]
3-Mercaptopropionic acid is a blocking drug that causes an increase in sleep and a decrease in wakefulness. A related finding is that nipecotic acid also increases the time needed for isoflurane to induce loss of consciousness, whereas 3-mercaptopropionic acid decreases anesthesia induction time[1].
