The full form of IPA hormone can refer to a few different compounds, depending on the context. The most likely and relevant meaning, especially in plant biology, is Indole-3-propionic acid.
Indole-3-propionic Acid (IPA)
-
IPA is a naturally occurring auxin, a type of plant hormone. Auxins are crucial for regulating various aspects of plant growth and development.
-
The reference mentions IPA as a natural antioxidant under study.
Other Possible Meanings (Less Likely in a Hormonal Context)
Although less likely to be the intended meaning when referring to a "hormone", it's worth noting other possibilities:
-
Isopropyl alcohol: Sometimes referred to as IPA. However, this is an alcohol and not a hormone.
-
International Phonetic Alphabet: Again, this is unrelated to hormones.
Therefore, in the context of a "hormone," Indole-3-propionic acid is the most accurate full form of IPA.
