In most mammalian tissues, ubiquinone (also called coenzyme Q) has 10 isoprene units.
Dolichols of animals have 17 to 21 isoprene units (85 to 105 carbon atoms), bacterial dolichols have 11, and those of plants and fungi have 14 to 24.

Lipids as pigments in plants and bird feathers.
Birds acquire the pigments that color their feathers red or yellow by eating plant materials that contain carotenoid pigments, such as canthaxanthin and zeaxanthin.
The differences in pigmentation between male and female birds are the result of differences in intestinal uptake and processing of carotenoids.
