{{sm|l}}-DOPA is a key [[chemical compound|compound]] in the formation of [[marine adhesive protein]]s, such as those found in [[mussel]]s.<ref>{{cite journal | vauthors = Waite JH, Andersen NH, Jewhurst S, Sun C | title=Mussel Adhesion: Finding the Tricks Worth Mimicking | journal=J Adhesion | volume=81 | year=2005 | pages=1–21 | doi=10.1080/00218460590944602 | issue=3–4 | s2cid=136967853 }}</ref><ref>{{cite web | url = https://www.sciencedaily.com/releases/2006/08/060816024159.htm | title = Study Reveals Details Of Mussels' Tenacious Bonds | publisher = Science Daily | date = 16 August 2006 | access-date = 30 September 2013}}</ref> It is believed to be responsible for the water-resistance and rapid curing abilities of these proteins. {{sm|l}}-DOPA may also be used to prevent surfaces from fouling by bonding antifouling polymers to a susceptible [[substrate (biochemistry)|substrate]].<ref>{{cite web | url = http://biomaterials.bme.northwestern.edu/mussel.asp | title = Mussel Adhesive Protein Mimetics | archive-url = https://web.archive.org/web/20060529181142/http://biomaterials.bme.northwestern.edu/mussel.asp | archive-date=29 May 2006 }}</ref> The versatile chemistry of {{sm|l}}-DOPA can be exploited in nanotechnology.<ref>{{cite journal | vauthors = Giuri D, Ravarino P, Tomasini C | title = L-Dopa in small peptides: an amazing functionality to form supramolecular materials | journal = Organic & Biomolecular Chemistry | volume = 19 | issue = 21 | pages = 4622–4636 | date = June 2021 | pmid = 33978030 | doi = 10.1039/D1OB00378J | s2cid = 234474122 | hdl = 11585/840774 | hdl-access = free }}</ref>  For example, DOPA-containing self-assembling peptides were found to form functional nanostructures, adhesives and gels.<ref>{{cite journal | vauthors = Fichman G, Adler-Abramovich L, Manohar S, Mironi-Harpaz I, Guterman T, Seliktar D, Messersmith PB, Gazit E | title = Seamless metallic coating and surface adhesion of self-assembled bioinspired nanostructures based on di-(3,4-dihydroxy-L-phenylalanine) peptide motif | journal = ACS Nano | volume = 8 | issue = 7 | pages = 7220–7228 | date = July 2014 | pmid = 24936704 | pmc = 4108209 | doi = 10.1021/nn502240r }}</ref><ref>{{cite journal | vauthors = Fichman G, Guterman T, Adler-Abramovich L, Gazit E | title = The Use of the Calcitonin Minimal Recognition Module for the Design of DOPA-Containing Fibrillar Assemblies | journal = Nanomaterials | volume = 4 | issue = 3 | pages = 726–740 | date = August 2014 | pmid = 28344244 | pmc = 5304689 | doi = 10.3390/nano4030726 | doi-access = free }}</ref><ref>{{cite journal | vauthors = Fichman G, Andrews C, Patel NL, Schneider JP | title = Antibacterial Gel Coatings Inspired by the Cryptic Function of a Mussel Byssal Peptide | journal = Advanced Materials | volume = 33 | issue = 40 | pages = e2103677 | date = October 2021 | pmid = 34423482 | pmc = 8492546 | doi = 10.1002/adma.202103677 | bibcode = 2021AdM....3303677F }}</ref><ref>{{cite journal | vauthors = Maity S, Nir S, Zada T, Reches M | title = Self-assembly of a tripeptide into a functional coating that resists fouling | journal = Chemical Communications | volume = 50 | issue = 76 | pages = 11154–11157 | date = October 2014 | pmid = 25110984 | doi = 10.1039/C4CC03578J }}</ref>

=== Plants and in the environment ===
In plants, <small>L</small>-DOPA functions as an [[allelochemical]] which inhibits the growth of certain species, and is produced and secreted by a few legume species such as the broad bean ''[[Vicia faba]]'' and the velvet bean ''[[Mucuna pruriens]]''.<ref>{{cite journal | vauthors = Fujii Y, Shibuya T, Yasuda T| title = L-3,4-Dihydroxyphenylalanine as an Allelochemical Candidate from Mucuna pruriens (L.)
