Patient's porphyrin levels must be through the roof.

病人的紫质程度一定高到爆了。

They create porphyrins, pigments that color blood red and chlorophyl green.

它们产生卟啉，这种色素使血变红色，叶绿变绿色。

Now, heme synthesis is also called porphyrin synthesis and when halted, it result in the buildup of one of its precursors molecules.

血红素合也被称为卟啉合，如果停止，这会导致它的一前体分子的积累。

This heme is a large molecule that's made up of four pyrrole subunits that forms a ring, and this structure is called a porphyrin.

血红素是大分子，四吡咯亚基形环形，这结构叫作卟啉。

In the 1920s and 1930s, biochemists—led by Hans Krebs and Carl and Gerty Cori—began to work out many of the central metabolic pathways of life: the citric acid cycle, glycogenesis and glycolysis, and the synthesis of steroids and porphyrins.

在二十世纪二三十年代，汉斯·克雷布斯（Hans Krebs）和卡尔（Carl Krert）和格蒂·科里（Gerty Cori）领导的生物化学家开始研究许多生命的中心代谢途径：柠檬酸循环，糖原合和糖酵解，以及类固醇和卟啉的合。
