En fosfolipid bildas genom att glycerolmolekyl förestras med två fettsyramolekyler och en fosfatgrupp bunden till en hydrofil grupp. De består alltså av ett hydrofilt huvud och en hydrofob svans vilket förenklat betyder att huvudet är vattenlösligt och svansen fettlöslig. Fosfolipider är huvudkomponenten för bildning av alla typer av cellmembran. Detta på grund av deras amfifila egenskaper vilket gör att de kan bilda lipida dubbelskikt. Fosfolipider produceras kommersiellt och de har ett antal olika tillämpningar inom bland annat <a href="/wiki/Materialvetenskap" title="Materialvetenskap">materialvetenskap</a> och <a href="/wiki/Nanoteknik" title="Nanoteknik">nanoteknik</a><sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-reference-link-bracket">[</span>1<span class="cite-reference-link-bracket">]</span></a></sup>. </p> <div class="mw-heading mw-heading2"><h2 id="Kemisk_struktur">Kemisk struktur</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Fosfolipid&amp;veaction=edit&amp;section=1" title="Redigera avsnitt: Kemisk struktur" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Fosfolipid&amp;action=edit&amp;section=1" title="Redigera avsnitts källkod: Kemisk struktur"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Fosfolipider är i grunden egentligen en glycerolmolekyl men i två av OH-grupperna har det fästs fettsyror. Det är dessa två man kallar “svansarna” och dessa är även den hydrofoba delen av molekylen. I den sista OH-gruppen sitter det en fosfatgrupp vilket då kännetecknar det polära “huvud” som fosfolipider har. </p><p>Eftersom “svansarna” består av <a href="/wiki/Fettsyra" title="Fettsyra">fettsyror</a> så kan det antingen vara mättade eller omättade. Mättade fettsyror innehåller inga dubbelbindningar medan omättade kan innehålla en eller flera, vilket i sin tur förändrar egenskaperna på följande sätt. Innehåller “svansen” dubbelbindningar så blir den inte helt rak, det vill säga att den böjer sig. Detta gör att membranet som fosfolipiderna befinner sig i blir svårare att frysa vilket i sin tur kan vara en fördel om cellen befinner sig i en kallare miljö.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-reference-link-bracket">[</span>2<span class="cite-reference-link-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Fosfolipider_i_cellmembran">Fosfolipider i cellmembran</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Fosfolipid&amp;veaction=edit&amp;section=2" title="Redigera avsnitt: Fosfolipider i cellmembran" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Fosfolipid&amp;action=edit&amp;section=2" title="Redigera avsnitts källkod: Fosfolipider i cellmembran"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Fosfolipider har en viktig funktion i alla organismers cellmembran. Fosfolipider består av en hydrofil del och en hydrofob del. I cellmembranet vänder fosfolipiderna de hydrofila delarna (huvudena) utåt mot angränsande vattenmiljö och de hydrofoba delarna (svansarna) inåt. Det bildar ett så kallat <a href="/wiki/Semipermeabelt_membran" title="Semipermeabelt membran">semipermeabelt membran</a> där endast hydrofoba och opolära ämnen kan tränga igenom fritt. Ett membran av fosfolipider kan förstöras genom att ändra <a href="/wiki/PH" title="PH">pH</a> samt att tillsätta ett starkt organiskt <a href="/wiki/L%C3%B6sningsmedel" title="Lösningsmedel">lösningsmedel</a>. Det ändrade pH:t löser de polära delarna av fosfolipiden, det vill säga huvudet, och det organiska lösningsmedlet kan användas för att lösa de hydrofoba svansarna. Ju fler <a href="/wiki/Dubbelbindning" class="mw-redirect" title="Dubbelbindning">dubbelbindningar</a> som finns på den hydrofoba svansen desto lättare bryts bindningarna, och smältpunkten sjunker, det vill säga membranet blir känsligare för höga temperaturer. </p> <div class="mw-heading mw-heading2"><h2 id="Referenser">Referenser</h2><span class="mw-editsection"><span
