Definition

Noun 1. The principal protein found in egg white: Ovalbumin is the major protein component of the albumin (the egg white) of bird eggs, serving as a source of nutrition for the developing embryo. 2. Egg white, albumen (in a scientific or technical context): The term can be used to refer to the egg white itself, particularly when discussing its chemical or biological properties.

Examples of Usage

• Noun:
  • Ovalbumin is a key allergen for many individuals with egg allergies.
  • In the laboratory, purified ovalbumin is often used as a standard protein in experiments.
  • The recipe requires the ovalbumin to be whipped into stiff peaks.

Advanced Usage

• "To denature ovalbumin": A biochemical process where the protein's structure is altered, typically by heat or acid, causing it to solidify (as when cooking an egg).
  • Heating ovalbumin causes it to denature and coagulate, turning the clear egg white opaque and solid.

Variants and Related Words

• Albumen (n): A synonym for egg white; the substance containing ovalbumin.
• Albumin (n): A broader class of simple, water-soluble proteins found in egg white, blood serum, and milk. Ovalbumin is a specific type of albumin.
• Conalbumin (n): Another significant protein found in egg white, distinct from ovalbumin.

Synonyms

• Egg white
• Albumen

Notes on Meaning

• In everyday cooking language, "egg white" is the common term. "Ovalbumin" is primarily used in scientific, medical (e.g., allergy research), and nutritional contexts to specify the protein.
• It is important to distinguish ovalbumin (the specific protein) from albumen (the substance, i.e., the egg white) and albumin (the general class of proteins).

Noun

1. the white part of an egg; the nutritive and protective gelatinous substance surrounding the yolk consisting mainly of albumin dissolved in water
   • she separated the whites from the yolks of several eggs
