Reynolds at Ohio State University and her teamwanted to better understand the evolution and function of these secondary metabolites. 俄亥俄州立大学的 Hannah T. Reynolds 和她的团队希望更好地了解这些次级代谢物的进化和功能。 Reel知识卷轴 But, brewing that blistering secondary metabolite is taxing on a plant, so it sacrifices other qualities such as flavors, sizes, and colors. 但是，生出灼热的次生代谢产物对植物来说是一种负担，所以辣椒的生长牺牲了其他品质，如味道、大小和颜色。 Reel知识卷轴 But brewing that blistering secondary metabolite is taxing on a plant, so it sacrifices other qualities, such as flavor, sizes and colors. 但酿造这种起泡的次生代谢物对植物来说是一种负担，所以它会牺牲其他品质，比如味道、大小和颜色。

次级代谢产物次级代谢产物（英语：Secondary metabolites，又称为次生代谢物、二代谢物）是不直接涉及到生命正常生长、发育或繁殖的有机化合物。不像初级代谢产物，缺少次级代谢产物不会导致立即死亡，但是在长期看来，会损伤生物的生存性、繁殖力或美学性，或者一点也没有明显的改变。次级代谢产物常被限定在系统发生学群体中的一个小系列里。次级代谢产物在植物防被食防卫方面起着重要的作用。人类利用次级代谢产物作为药物、调味品或消遣类药物。细菌利用抗生素来和周围的细菌合作和沟通，常常次级代谢都发生在细菌成长期之后的固定期（stationary phase），而人类使用提炼出来的抗生素做药物。
英语百科
Secondary metabolite 次级代谢产物Secondary metabolites are organic compounds that are not directly involved in the normal growth, development, or reproduction of an organism. Unlike primary metabolites, absence of secondary metabolites does not result in immediate death, but rather in long-term impairment of the organism's survivability, fecundity, or aesthetics, or perhaps in no significant change at all. Secondary metabolites are often restricted to a narrow set of species within a phylogenetic group. Secondary metabolites often play an important role in plant defense against herbivory and other interspecies defenses. Humans use secondary metabolites as medicines, flavorings, and recreational drugs. |
