There is a membrane called yolk membrane on the surface of egg yolk, which is the innermost protective structure in the internal structure of egg. Generally, yolk consists of yellow yolk and white yolk in concentric circles, with yolk heart in the middle. There is a small white disk (like a small white dot) on the yolk, which is composed of a part of cytoplasm and nucleus. When the egg is not fertilized, the blastoderm is light and small, and when the egg is fertilized, the blastoderm is thick and slightly larger. After fertilization, the blastoderm can hatch chickens under suitable conditions. The blastoderm, yolk membrane and yolk together form an egg cell.
Most of the fat in eggs is concentrated in the yolk. The fat in egg yolk is mainly monounsaturated fatty acid, more than half of which is oleic acid, the main component of olive oil, which is beneficial to prevent heart disease.
Vitamins are also mostly concentrated in egg yolk. Egg yolk contains valuable vitamins A and D, as well as vitamin E and vitamin K, which are "fat-soluble vitamins". Most water-soluble B vitamins also exist in egg yolk. The reason why egg yolk is light yellow is because it contains riboflavin, which is vitamin B2. It can prevent mouth rot, glossitis and cleft lip.
