'''3-Hydroxypropionic acid''' is a ], specifically a ]. It is an acidic viscous liquid with a ] of 4.9.<ref name="CRC"/> It is very soluble in water, soluble in ] and ]. Upon distillation, it ] to form ], and is occasionally called '''hydracrylic acid'''

3-Hydroxypropionic acid is used in the industrial production of various chemicals such as ]s.

==Synthesis==
3-Hydroxypropionic acid can be obtained by base-induced hydration of acrylic acid followed by reacidification. Another synthesis involves cyanation of ethylene chlorohydrin followed by hydrolysis of the resulting nitrile. Hydrolysis of ] is yet another route.<ref name=Ullmann>{{Ullmann|doi=10.1002/14356007.a13_507|title=Hydroxycarboxylic Acids, Aliphatic|year=2000|last1=Miltenberger|first1=Karlheinz|isbn=3527306730}}</ref> Propiolactone, the dehydrated derivative of 3-hydroxypropionic acid, is produced by reaction of ] and ].<ref name=CR/>

3-Hydroxypropionic acid is listed as one of the "top" chemicals that could be produced from renewable resources. In particular, it could be produced by manipulation of ], but this technology has not reached a commercial stage.<ref name=topten>{{cite journal |doi=10.1039/b922014c |title=Technology development for the production of biobased products from biorefinery carbohydrates—the US Department of Energy's "Top 10" revisited |date=2010 |last1=Bozell |first1=Joseph J. |last2=Petersen |first2=Gene R. |journal=Green Chemistry |volume=12 |issue=4 |page=539 }}</ref> It can also be produced from glucose via pyruvate and malonyl coenzyme A.<ref name=CR>{{cite journal |doi=10.1021/acs.chemrev.7b00395 |title=Catalytic Conversion of Carbohydrates to Initial Platform Chemicals: Chemistry and Sustainability |date=2018 |last1=Mika |first1=László T. |last2=Cséfalvay |first2=Edit |last3=Németh |first3=Áron |journal=Chemical Reviews |volume=118 |issue=2 |pages=505–613 |pmid=29155579 }}</ref><ref>{{cite journal |doi=10.1080/07388551.2016.1272093 |title=Malonyl-CoA pathway: A promising route for 3-hydroxypropionate biosynthesis |date=2017 |last1=Liu |first1=Changshui |last2=Ding |first2=Yamei |last3=Xian |first3=Mo |last4=Liu |first4=Min |last5=Liu |first5=Huizhou |last6=Ma |first6=Qingjun |last7=Zhao |first7=Guang |journal=Critical Reviews in Biotechnology |volume=37 |issue=7 |pages=933–941 |pmid=28078904 }}</ref>

==Potential applications==
3-Hydroxypropionic acid is of interest as a bio-derived precursor to ].<ref name=topten/>

The ] poly(3-hydroxypropionic acid) is a ].<ref>{{cite web|title=3-HP|url=http://www.license.umn.edu/Products/Biodegradable-Polyester-Produced-From-Non-toxic--Renewable-Monomer__Z05135.aspx|access-date=27 May 2011}}</ref> The method combines the high-molecular weight and control aspects of ] with the commercial availability of the beta hydroxy acid, 3-hydroxypropionic acid which is abbreviated as 3-HP. Since 3-HPA can be derived from biological sources, the resulting material, poly(3-hydroxypropionic acid) or P(3-HPA), is biorenewable.

==Genetically encoded 3-hydroxypropionic acid inducible system==
3-Hydroxypropionic acid can be produced by engineered ].<ref>{{Cite web|url=http://www.popsci.com/science/article/2013-03/scientists-are-engineering-volcanic-microorganisms-chew-co2-spit-back-fuel|title = Scientists Engineer Extreme Microorganisms to Make Fuel from Atmospheric Carbon Dioxide|date = 27 March 2013}}</ref>

A genetically encoded 3-hydroxypropionic acid inducible system has been characterized in bacteria demonstrating that such system in combination with fluorescent reporter protein can be utilized as a biosensor to measure intracellular and extracellular 3-HP concentrations by fluorescence output.<ref>{{cite journal|last1=Hanko |first1=E.K.R. |last2=Minton |first2=N.P. |last3=Malys |first3=N. |title=Characterisation of a 3-hydroxypropionic acid-inducible system from ''Pseudomonas putida'' for orthogonal gene expression control in ''Escherichia coli'' and ''Cupriavidus necator'' |journal=Scientific Reports |volume=7 |number=1724 |date=2017 |page=1724 |doi=10.1038/s41598-017-01850-w |pmid=28496205 |pmc=5431877 |bibcode=2017NatSR...7.1724H}}</ref>
