Editing Proline (section)

==Uses==
Proline and its derivatives are often used as asymmetric catalysts in [[proline organocatalysis]] reactions. The [[CBS reduction]] and proline catalysed [[aldol condensation]] are prominent examples.

In brewing, proteins rich in proline combine with polyphenols to produce haze (turbidity).<ref>{{cite web | vauthors = Siebert KJ | title = Haze and Foam | url= http://www.nysaes.cornell.edu/fst/faculty/siebert/haze.html |website=Cornell AgriTech |access-date=2010-07-13 |url-status=live |archive-url=https://web.archive.org/web/20100711180909/http://www.nysaes.cornell.edu/fst/faculty/siebert/haze.html |archive-date=2010-07-11 }} Accessed July 12, 2010.</ref>

<small>L</small>-Proline is an [[osmoprotectant]] and therefore is used in many pharmaceutical and biotechnological applications.

The [[growth medium]] used in [[plant tissue culture]] may be supplemented with proline.  This can increase growth, perhaps because it helps the plant tolerate the stresses of tissue culture.<ref name="pazuki">{{cite journal | vauthors = Pazuki A, Asghari J, Sohani MM, Pessarakli M, Aflaki F |year=2015 |title= Effects of Some Organic Nitrogen Sources and Antibiotics on Callus Growth of Indica Rice Cultivars |journal= Journal of Plant Nutrition |volume=38 |issue=8 |pages=1231–1240 |doi=10.1080/01904167.2014.983118 |bibcode=2015JPlaN..38.1231P |s2cid=84495391 }}</ref>{{Better source needed|reason=Source is a primary study, claiming supplementation improves rice growth.
