多烯

Polyene

多烯是含有一个或多个交替双和单碳 - 碳键序列的多不饱和有机化合物。 这些双碳 - 碳键在称为共轭的过程中相互作用,这导致分子的总体较低能量状态。 两性霉素B是黄色多烯抗真菌剂的实例。 注意中心的交替双和单键。 通常,不共轭或仅与一个或两个其他碳 - 碳双键结合的碳 - 碳双键具有足够的能量,它们在光谱的紫外区域吸收,但具有多个共轭双键的多烯的吸收能态 可以降低键,使得它们进入光谱的可见区域,导致着色的化合物。 许多脂肪酸是多烯,许多染料含有线性多烯。 多烯化合物的其它实例包括β-胡萝卜素,其根据浓度为黄色至橙色,以及多烯抗真菌剂,其中一些为黄色。 Polyenes are poly-unsaturated organic compounds that contain one or more sequences of alternating double and single carbon–carbon bonds. These double carbon–carbon bonds interact in a process known as conjugation, which results in an overall lower energy state of the molecule. Amphotericin B is an example of a yellow-coloured polyene antifungal agent. Note the alternating double and single bonds in the center. Normally carbon–carbon double bonds which are not conjugated or only conjugated with only one or two other carbon–carbon double bonds have high enough energy that they absorb in the ultraviolet region of a spectrum, but the absorption energy state of polyenes with numerous conjugated double bonds can be lowered such that they enter the visible region of the spectrum, resulting in compounds which are coloured. Many fatty acids are polyenes, and many dyes contain linear polyenes. Other examples of polyene compounds include beta-carotene, which is yellow to orange coloured depending on concentration, and polyene antimycotics, some of which are yellow coloured.
