《生物因子》是一份國際期刊，旨在確定和增進我們對生物體所需要的大量微量物質(zhì)的精確生化作用和作用的理解。這些物質(zhì)包括維生素和微量元素，以及細胞自身產(chǎn)生的生長因子和調(diào)節(jié)物質(zhì)。在一個特定的有機體或細胞系中，闡明微量活性物質(zhì)的作用，常常直接適用于許多其他形式的生命。為了保持這種生物化學的統(tǒng)一觀點，《生物因子》發(fā)表了關于新物質(zhì)的鑒定和在基本生物化學水平上闡明其功能以及揭示已知微量物質(zhì)的新功能的文章。

BioFactors is an international journal aimed at identifying and increasing our understanding of the precise biochemical effects and roles of the large number of trace substances that are required by living organisms. These include vitamins and trace elements, as well as growth factors and regulatory substances made by cells themselves. The elucidation, in a particular organism or cell line, of the roles of substances active in trace quantities, is frequently applicable directly to many other forms of life. In keeping with this unified view of biochemistry, BioFactors publishes articles dealing with the identification of new substances and the elucidation of their functions at the basic biochemical level as well as those revealing novel functions of trace substances already known.
