Carotene Hydroxylase Activity Determines the Levels of Both α-Carotene and Total Carotenoids in Orange Carrots.
The typically intense carotenoid accumulation in cultivated orange-rooted carrots (Daucus carota) is determined by a high protein abundance of the rate-limiting enzyme for carotenoid biosynthesis, phytoene synthase (PSY), as compared with white-rooted cultivars. However, in contrast to other carotenoid accumulating systems, orange carrots are characterized by unusually high levels of α-carotene...

Unlike most species, humans cooperate extensively with group members who are not closely related to them, a pattern sustained in part by punishing non-cooperators and rewarding cooperators. Because internally cooperative groups prevail over less cooperative rival groups, it is thought that violent intergroup conflict played a key role in the evolution of human cooperation. Consequently, it is p...
متن کاملBioavailability of b-carotene (bC) from purple carrots is the same as typical orange carrots while high-bC carrots increase bC stores in Mongolian gerbils (Meriones unguiculatus)
Vitamin A (VA) deficiency is a worldwide public health problem. Biofortifying existing sources of b-carotene (bC) and increasing dietary bC could help combat the issue. Two studies were performed to investigate the relative bC bioavailability of a bC supplement to purple, high-bC orange, and typical orange carrots using Mongolian gerbils (Meriones unguiculatus). In study 1, which used a traditi...
متن کاملBioconversion Efficiency of β-Carotene from Mango Fruit and Carrots in Vitamin A
Problem statement: Bioconversion efficiency of β-Carotene (BC) in vitamin A is strongly influenced by food matrix. This efficiency has been determined mainly in typical BC sources like carrots. BC content in mango fruit is considerably high however; the bioconversion efficiency of BC from fresh mango in vitamin A has not been determined nor compared with those of typical BC sources. Approach: V...
