类胡萝卜素是鸟类羽毛中的重要成分。代谢前体来源于饮食，但许多物种有能力对色素进行化学修饰和选择性沉积。随之而来的羽毛图案在交流和识别中很重要。鲜艳的黄色、橙色和红色主要是由于叶黄素、酮类和羟基胡萝卜素。有些是未经修饰的(如叶黄素)，而另一些是化学修饰的(角黄质、虾黄素)。早期的研究人员专注于证明羽毛类胡萝卜素是从饮食中提取出来的，并有选择性地沉积。在定义和解决生物学问题方面的进展取决于化学和分析技术的进步。随后的研究表明，各种羽毛颜色、季节羽毛变化或常见突变体的颜色，都是由于类胡萝卜素相对简单的化学变化所致，但具有深刻的生物学后果。同样重要的是，人们意识到这些过程中的许多都是在基因控制下进行的。验证来自对火烈鸟和雀类的喂养研究。最近的研究利用羽毛类胡萝卜素来验证遗传分化的假说，将羽毛颜色与环境过程联系起来，并证明合成变化对颜色的影响。随着高分辨率分离技术的引入以及确定构象和绝对构型的能力的引入，人们对这些过程的理解有所进步。下一步将朝着了解类胡萝卜素的酶修饰、运输和组织选择性的方向。-Brush，A.H.鸟类中类胡萝卜素的新陈代谢。FASE B J.4：2969-2977；1990。
Carotenoid pigments are an important component in the plumage of birds. The metabolic precursors are dietary in origin but many species have the capacity to chemically modify and selectively deposit the pigments. The ensuing plumage patterns are important in communication and identification. The bright yellows, oranges, and reds are due mostly to xanthophylls; keto and hydroxy carotenes. Some are deposited unmodified (e.g., lutein) whereas others are modified chemically (canthaxanthin, astaxanthin). Early workers concentrated on demonstrating that feather carotenoids were derived from the diet and deposited selectively. Progress in defining and solving biological problems depended on advances in chemical and analytical techniques. Subsequent investigation showed that various plumage colormorphs, seasonal plumage changes or colors in common mutant, were due to relatively simple chemical changes in carotenoids but had profound biological consequences. Equally important was the realization that many of these processes were under genetic control. Validation came from feeding studies of flamingos and finches. Recent studies have employed the plumage carotenoids to test hypotheses of genetic divergence, to relate plumage color to environmental process, and to demonstrate the influence of synthetic changes on color. Understanding the processes has advanced with the introduction of high‐resolution separation techniques and the ability to determine both conformation and absolute configuration. The next steps will be in the direction of understanding the enzymatic modification, transport, and tissue selectivity of feather carotenoids.— Brush, A. H.
