After serotonin is pumped into the synapse, it is either taken up into the pre-synaptic neuron for later use or it is metabolized by an enzyme into 5-hydroxyindole acetic acid (5-HIAA).

5-羟色胺“泵”入神经突触后，要到前突触神经元备用，要某种酶代谢成 5-羟吲哚乙酸（5-HIAA）。

Here, an online intelligent monitoring system for indole-3-acetic acid (IAA) was proposed, including reusable microsensor, portable electrochemical workstation, and online cloud platform.

此，提出了一种吲哚-3-乙酸（IAA）智能监测系统，该系统包括可重复使用微传感器、便携式电化学工作站以及云平台。
