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.
How an Egg is Formed. An egg is formed over a period of about 25 hours. The egg yolks are formed in the hen's ovary. Hens, unlike most animals, have only one functional ovary, the left one. At the time of hatch each female chick will have up to 4 000 tiny ova, from some of which yolks may develop when the hen matures.ow an Egg is Formed. An egg is formed over a period of about 25 hours.
