When someone had been exposed to valeric acid, for example, he tended to react negatively to a face. 比如某人闻到缬草酸时，他对看到的脸就会有不好的反应。
The physical property of pregabalin and six different synthetic routes for preparing pregabalin starting with 4-methyl valeric acid and isovaleraldehyde were introduced separately. 介绍普瑞巴林的物理性质及其6种分别以4-甲基戊酸和异戊醛为原料的不同合成方法。
When RDP/RUP of diet was 1.73, the concentrations of acetic acid (P<0.05), propionate acid (P<0.05), butyric acid (P<0.01), valeric acid (P<0.05) and total VFA (P<0.01) of rumen fluid were significantly higher than other three diets. 当RDP/RUP值为1.
