The <a href="/wiki/Epithelial_cell" class="mw-redirect" title="Epithelial cell">epithelial cells</a> of the <a href="/wiki/Small_intestine" title="Small intestine">small intestine</a> produce citrulline, primarily from <a href="/wiki/Glutamine" title="Glutamine">glutamine</a> and <a href="/wiki/Glutamate" class="mw-redirect" title="Glutamate">glutamate</a>, which is secreted into the bloodstream which carries it to the <a href="/wiki/Proximal_tubule_cell" class="mw-redirect" title="Proximal tubule cell">proximal tubule cells</a> of the <a href="/wiki/Kidney" title="Kidney">kidney</a>, which extract the citrulline and convert it to arginine, which is returned to the blood. This means that impaired small bowel or renal function can reduce arginine synthesis and thus create a dietary requirement for arginine. For such a person, arginine would become "essential". </p><p>Synthesis of arginine from citrulline also occurs at a low level in many other cells, and cellular capacity for arginine synthesis can be markedly increased under circumstances that increase the production of <a href="/wiki/Nitric_oxide_synthase#iNOS" title="Nitric oxide synthase">inducible nitric oxide synthase (NOS)</a>. This allows citrulline, a byproduct of the NOS-catalyzed production of nitric oxide, to be recycled to arginine in a pathway known as the citrulline to nitric oxide (citrulline-NO) or arginine-citrulline pathway. This is demonstrated by the fact that, in many cell types, nitric oxide synthesis can be supported to some extent by citrulline, and not just by arginine. This recycling is not quantitative, however, because citrulline accumulates in nitric oxide producing cells along with <a href="/wiki/Nitrate" title="Nitrate">nitrate</a> and <a href="/wiki/Nitrite" title="Nitrite">nitrite</a>, the stable end-products of nitric oxide breakdown.<sup id="cite_ref-24" class="reference"><a href="#cite_note-24"><span class="cite-bracket">[</span>24<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Function">Function</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Arginine&action=edit&section=6" title="Edit section: Function"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Arginine plays an important role in <a href="/wiki/Cell_division" title="Cell division">cell division</a>, <a href="/wiki/Wound_healing" title="Wound healing">wound healing</a>, removing ammonia from the body, <a href="/wiki/Immune_function" class="mw-redirect" title="Immune function">immune function</a>,<sup id="cite_ref-25" class="reference"><a href="#cite_note-25"><span class="cite-bracket">[</span>25<span class="cite-bracket">]</span></a></sup> and the release of hormones.<sup id="cite_ref-tapiero_14-1" class="reference"><a href="#cite_note-tapiero-14"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-26" class="reference"><a href="#cite_note-26"><span class="cite-bracket">[</span>26<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-27" class="reference"><a href="#cite_note-27"><span class="cite-bracket">[</span>27<span class="cite-bracket">]</span></a></sup> It is a precursor for the synthesis of <a href="/wiki/Nitric_oxide" title="Nitric oxide">nitric oxide</a> (NO),<sup id="cite_ref-28" class="reference"><a href="#cite_note-28"><span class="cite-bracket">[</span>28<span class="cite-bracket">]</span></a></sup> making it important in the regulation of <a href="/wiki/Blood_pressure" title="Blood pressure">blood pressure</a>.<sup id="cite_ref-29" class="reference"><a href="#cite_note-29"><span class="cite-bracket">[</span>29<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-30" class="reference"><a href="#cite_note-30"><span class="cite-bracket">[</span>30<span class="cite-bracket">]</span></a></sup> Arginine is necessary for T-cells to function in the body, and can lead to their deregulation if depleted.<sup id="cite_ref-31" class="reference"><a href="#cite_note-31"><span class="cite-bracket">[</span>31<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-32" class="reference"><a href="#cite_note-32"><span class="cite-bracket">[</span>32<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Proteins">Proteins</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Arginine&action=edit&section=7" title="Edit section: Proteins"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Arginine's side chain is <a href="/wiki/Amphiphile" title="Amphiphile">amphipathic</a>, because at physiological pH it contains a positively charged guanidinium group, which is highly polar, at the end of a hydrophobic <a href="/wiki/Aliphatic_compound" title="Aliphatic compound">aliphatic</a> hydrocarbon chain.
