betalain化学式betalain化学式 Betalains是一类植物色素,主要存在于甜菜属植物和仙人掌科植物中。它们被分为两类,红色的betacyanins和黄色的betaxanthins。Betacyanins的化学结构是由一个或多个氨基酸和一个或多个糖基连接在一起,形成一个带有芳香环的分子。它们的化学式通常可以表示为R1-(C15H11N2O)+R2,其中R1和R2...
Mello et al. (2015)carried out a study to quantify betalain content and its stability and observed that the Pitaya bark has 101.04 mg of betalain equivalent. The compounds were stable in the pH range of 3.2–7, with the most considerable degradation observed at pH 2.4, followed by pH 8...
It was found that the decisive steps in betalain biosynthesis, i.e. condensation of the betalain chromophore betalamic acid with cyclo-dopa and amino acids or amines in the respective aldimine formation of the red-violet betacyanins and the yellow betaxanthins, are most likely to be non-...
Finally, we investigated betalain transport in CEN.PK and S288C strains of Saccharomyces cerevisiae and identified a possible role of transporter genes QDR2 and APL1 in betanin transport. Conclusions This study shows the potential of combinatorial engineering of yeast cell factories for the ...

clade in betalain biosynthesis have not been determined. Duplication events in theDODAgene lineage also gave rise to two major clades: DODAα and DODAβ. The function of DODAβ is unknown, but the evolution of L-DOPA 4,5-dioxygenase activity in betalain-producing plants was proposed to be ...
