Abstract
Kolesterol, jedan od glavnih sastojaka žumanjka jajeta, je po kemijskom sastavu lipid, točnije sterol. Smatra ga se esencijalnim jer mijenja fluidnost životinjskim staničnim membranama i preteča je steroidnih hormona. Nalazi se u hrani životinjskog podrijetla. Do visokih koncentracija kolesterola u organizmu dolazi pretjeranom konzumacijom hrane bogate kolesterolom. Uz to, na visoku koncentraciju utječe i sposobnost organizma da sam sintetizira kolesterol. Višak kolesterola se taloži na stjenkama arterija kao LDL-kolesterol (eng. low density cholesterol) tzv. „loš“ kolesterol. Višak LDL-kolesterola uklanja HDL-kolesterol (eng. high density cholesterol) ili „dobar“ kolesterol. Cilj ovog istraživanja bio je odrediti koncentraciju kolesterola u uzorcima žumanjka tekućinskom kromatografijom vrlo visoke razlučivosti (UPLC, eng. ultra performance liquid chromatography). Tekućinska kromatografija je, uz plinsku kromatografiju, najčešća metoda određivanja koncentracije kolesterola.
Abstract (english)
Cholesterol, one of the main ingredient of an egg yolk, is by its chemical composition lipid, precisely sterol. It is considered to be essential because it changes fluidity of animal cell membranes and is forerunner for steroid hormones. Cholesterol can be found in food of animal origion. High concentrations of cholesterol in the body occur by excessive consuming cholesterol rich food. Cholesterol biosynthesis also affects on high concentration. Cholesterol excess deposits on artery walls as LDL-cholesterol (low density cholesterol) also known as „bad“ cholesterol. The LDL-cholesterol excess is removed by HDL-cholesterol (high density cholesterol) or „good“ cholesterol. The purpose of this research was to quantify the concentration of cholesterol in the egg yolk samples by UPLC (ultra performance liquid chromatography). Liquid chromatography, along with gas chromatography, is the most common method to quantify the concentration of cholesterol.
