摘要
在1 M HCl或1 M NaOH中消化的幼体松果体器官的分光光度测定显示,吸收峰分别在253 nm和268 nm处。这一结果与在七鳃鳗松果体中发现的晶体是由鸟嘌呤化学组成的观点不一致。
Crystals in supporting cells of pineal organ in larval lamprey not likely to be pure guanine.
Spectrophotometry of larval pineal organs, digested in either 1 M HCl or 1 M NaOH, revealed peak absorbances at 253 nm and 268 nm, respectively. This result is not consistent with the view that the crystals found in lamprey pineals are chemically made of guanine.
