血清素合成及代谢

血清素（5-羟色胺）主要存在于三种主要细胞类型中：i）中杻神经系统（CNS）和肠肌间神经丛中的血清素能神经元，ii）胃肠道粘膜中的肠嗜铬细胞，和iii）血小板。血清素的代谢主要通过外部线粒体膜酶单胺氧化酶（MAO）进行，它以两种分子亚型存在，分别称为MAO-A和MAO-B。

Serotonin Synthesis & Metabolism

Serotonin is stored in cells and metabolized by MAO, influencing CNS, GI, and platelet functions.

Questions

1–2 of 2 Questions  

  1. What is the lambda max for genistin and what is the molar extinction coefficient at that wavelength?

    1 answer

    1. We have data from our QC labs here at Sigma on one of the Genistin products we offer, G0897. The solvent is 85% ethanol/15% water, and the lambda max is typically 262.0 or 262.5 nm. We measured the molar extinction coefficients at the lambda max for four different lots of G0897 back in the 1990s, and the average value was 39,800 M-1.Genistin is a derivative of Genistein. There is an entry for Genistein in the chemicals encyclopedia published by the Royal Society of Chemistry, with information for Genistin under that heading.According to the chemicals encyclopedia published by the Royal Society of Chemistry, 14th edition, entry #4391, uv max (85% ethanol) 262.5 nm (a 90.5)".The value of ""a 90.5"" is the same as an E0.1%, or the extinction coefficient for a 1 mg/mL (or 1 gram per Liter) solution.If one multiplies 90.5 (L/g) by the molecular weight of genistin (432.38 g/mole), you get 39,130 M-1. This is pretty close to the value of 39,800 from our data above."
