description. Egg yolk forms about 30% of an egg. It is the part of an egg which feeds the embryo, hence it is a major source of fat, protein, vitamin and minerals. Egg yolk mainly consists of protein and lipids, The lipid part is almost fully bound to proteins, as lipoproteins. This is why egg yolk is a good emulsifier.
The Formation of an Egg (inside a chicken): The Yolk: The chicken egg starts as an egg yolk inside a hen. A yolk (called an oocyte at this point) is produced by the hen's ovary in a process called ovulation. Fertilization: The yolk is released into the oviduct (a long, spiraling tube in the hen's reproductive system), where it can be fertilized internally (inside the hen) by a sperm.
