Katabolni proces presnove galaktoze ne obstaja, zato uridin pretvori galaktozo v [http://sl.wikipedia.org/wiki/Glukoza glukozo], ta pa se razgradi v navadnem glikoliznem ciklu. Ko se galaktoza pretvori v galaktozo-1-fosfat, je vključena v reakcijo z UDP-glukozo, kjer je glukozna molekula vezana na UDP (uridin-di-fosfat) molekulo. Ta proces katalizira [http://sl.wikipedia.org/wiki/Encim encim] galaktoza-1-fosfat uridil transferaza, ki prenese UDP do molekule galaktoze. Končni rezultat sta molekuli UDP-galaktoza in glukoza-1-fosfat. Ta proces se nadaljuje, da se omogoči pravilna glikoliza za molekulo galaktoze.<br /> <br /> == ZANIMIVOST ==<br /> Raziskovalci s harvarda poročajo, da imajo prehrambeni dodatki v obliki uridina in EPA/DHA omega-3 maščobnih kislin na podgane antidepresiven učinek, ki je enakovreden tistemu, ki ga povzročajo zdravila, kot so Prozac in ostali antidepresivi, ki se jih predpisuje vsakodnevno. <br /> <br /> == VIRI ==<br /> http://www.ncbi.nlm.nih.gov/books/NBK22593/#A2239 <br /> <br /> http://en.wikipedia.org/wiki/Uridine<br /> <br /> http://www.biologicalpsychiatryjournal.com/article/S0006-3223%2804%2901261-2/abstract<br /> <br /> ----<br /> [[Category:LEX]]</div> Mateja Škratek
