酸味物质

Although allene oxide synthase and hydroperoxide lyase are atypical cytochrome P450 family members involved in the synthesis of jasmonates and GLVs, respectively, it is unknown how these enzymes rearrange their hydroperoxide substrates into different products.

这些酶是两种物质的综合体，包括allene氧化物（allene oxide synthase，简称AOS）和过氧化氢酶（hydroperoxide lyase ，简称HPL），它能产生茉莉酸味和一种绿叶中含有的挥发物GLV，后者决定了蔬菜和水果的芳香特点。

The effect of adaptation to bitter substances (e.g., caffeine, quinine) can elicit or potentiate a sweet taste from water; adaptation to sweet substances (sucrose, fructose, and saccharin) results in a sour and bitter taste from water; adaptation to salts potentiates sour, sweet, and some bitter water tastes; and a sour adapting solution (e.g., citric acid) can produce a sweet water taste.

对苦味物质的适应影响可以引起或加强水的甜味。甜味物质的适应会引发水中的酸味和苦味。对咸味的适应会让水尝起来有酸味，甜味和一些苦味。对酸味的适应会让水尝起来甜。
