Queuine, a modified base found in transfer RNA, appears to be a new dietary factor because (i) previous studies have shown that mice require it for the expression of queuine-containing transfer RNA's but apparently do not synthesize it, and (ii) significant amounts of free queuine are present in common plant and animal food products.
喹啉是转运核糖核酸中发现的一种修饰碱基，它似乎是一种新的膳食因子，原因如下：（i）先前的研究表明，小鼠表达含喹啉的转运核糖核酸需要它，但显然无法合成它；（ii）常见的动植物食品中存在大量游离喹啉。
