An egg white is mainly made of a protein called:

➡Ovalbumin: The primary protein in egg white, ovalbumin provides nourishment and binds digestive enzymes. It makes up approximately 54% of the protein in egg albumen (source).

In humans the compound used to transport of oxygen in respiration is known as:

➡Hemoglobin is composed of four iron-containing ring structures (hemes) chemically bonded to a large protein (globin).

➡Each iron atom can bind and then release an oxygen molecule. Enough hemoglobin is present in normal human blood to permit transport of about 0.2 millilitre of oxygen per millilitre of blood.

Answer:

Glycoproteins are proteins which contain oligosaccharide chains (glycans) covalently attached to amino acid side-chains. The carbohydrate is attached to the protein in a cotranslational or posttranslational modification. This process is known as glycosylation. Secreted extracellular proteins are often glycosylated.
