this gives us the structural formula of the molecule . 這種方式給出了分子的結(jié)構(gòu)式。
before we can assign a structural formula to a compound, we must first know its molecular formula . 在確定一個化合物的結(jié)構(gòu)式之前,首先應(yīng)知道它的分子式。
structural formulas of amino acids 氨基酸的結(jié)構(gòu)式
its structural formula 生產(chǎn)出廠指標(biāo):
appropriate chemical attribute information, such as structural formula, empirical formula, and molecular weight 適當(dāng)?shù)幕瘜W(xué)性質(zhì)資料,比如結(jié)構(gòu)式,經(jīng)驗式和分子量等。
