U ovom radu opisani su prirodni organski spojevi iz grupe terpenoida - karotenoidi. Navedena je funkcija ove skupine spojeva u biljkama u kojima se pretežno nalaze. Također je opisana važnost karotenoida za ljudsko zdravlje. U radu je dan kratak pregled glavnih bioloških aktivnosti karotenoida zbog kojih se oni intenzivno istražuju diljem svijeta te ...

Karotenoidy. Naturalne źródła, biosynteza, wpływ na organizm ludzki
2011Carotenoids belong to a group of compounds characterized by a general ability to protect the body against many serious diseases, such as impaired growth of children, the occurrence of many types of cancer, eye damage. Protective effect of carotenoids is associated mainly with the ability to scavenger free radicals and reactive oxygen species.

Karotenoidi: stabilnost i važnost u prehrambenim proizvodima
2011Karotenoidi su pigmenti topljivi u uljima i organskim otapalima, a boja im varira od žute, preko narančaste pa do crvene. Razlikuju se dvije strukturne grupe karotenoida: karoteni i ksantofili. Osnovnu strukturu karotenoida čine kovalentno povezane izoprenske jedinice, a na kraju lanca se nalaze prsten ili otvoreni lanac. Najzastupljeniji karotenoid je

Zhášení tripletních stavů chlorofylů karotenoidy v tylakoidních membránách
2015Photosynthesis is one of the most important biological processes. The photosynthetic apparatus is protected against formation of reactive singlet oxygen by carotenoids. In this work, thylakoid membranes from spinach were studied, and the main aim was to explore the effect of a partial carotenoid removal on the protective function.

The phenotype-linked fertility hypothesis predicts that both, male carotenoid-based sexual ornamentation and their spermatozoa are phenotypically plastic and may be co-affected by the environment. One of the factors affecting their phenotype may be oxidative stress and the ability of organism to eliminate its effect.
