Conalbumin: Conalbumin is one of the two major types of albumin found in egg white. It comprises approximately 13% of albumen (in contrast to ovalbumin, which comprises 54%).Chicken as biological research model: Chickens (Gallus gallus domesticus) and their eggs have been used extensively as research models throughout the history of biology. Today they continue to serve as an important model for normal human biology as well as pathological disease processes.Neodymium: Neodymium is a chemical element with symbol Nd and atomic number 60. It is a soft silvery metal that tarnishes in air.Ovalbumin: Ovalbumin (abbreviated OVA) is the main protein found in egg white, making up 60-65% of the total protein.
