Ovalbumin, also known as albumin or OVA, is the most abundant protein found in egg white, accounting for approximately 54% of its total protein content. This versatile glycoprotein has captivated researchers and industry professionals alike due to its unique properties and wide-ranging applications. In this article, we’ll explore the structure, functions, and diverse uses of ovalbumin in various fields.

Structure and Properties

Ovalbumin peptide is a 45 kDa protein consisting of 385 amino acids. Its three-dimensional structure is characterized by a single polypeptide chain that folds into a globular shape, stabilized by one disulfide bond. The protein contains both hydrophilic and hydrophobic regions, which contribute to its solubility and emulsifying properties.

One of the most intriguing aspects of ovalbumin is its ability to undergo conformational changes in response to environmental factors such as temperature and pH. This property, known as serpin-like behavior, allows ovalbumin to transition between active and inactive states, influencing its functionality in various applications.

Biological Functions

In nature, ovalbumin serves several important functions:

1. Nutrient source: As a major component of egg white, ovalbumin provides essential amino acids for the developing embryo.

2. Antimicrobial activity: Some studies suggest that ovalbumin may possess antimicrobial properties, contributing to the egg’s natural defense against pathogens.

3. Transport protein: Ovalbumin can bind and transport small molecules, potentially playing a role in nutrient delivery within the egg.
