Silver vitellin is a phrase widely used in medical and scientific fields to describe a component of an egg yolk. It is a protein that plays a crucial role in embryonic development. Several synonyms can be used in place of silver vitellin, such as vitellin, egg yolk protein, and ovalbumin. Vitellin is commonly used in the field of reproductive biology, while egg yolk protein is widely used in the food industry. Ovalbumin, on the other hand, is a distinct protein found in egg whites. Despite their different names, these proteins share similar functions and are crucial for the proper growth and development of embryos.
