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.
For other uses, see Embryo (disambiguation). An embryo is an early stage of development of a multicellular diploid eukaryotic organism. In general, in organisms that reproduce sexually, an embryo develops from a zygote, the single cell resulting from the fertilization of the female egg cell by the male sperm cell.
