In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Egg white. A raw egg with the round orange yolk (containing the visible white chalaza) in the center surrounded by the transparent yellow egg white. Egg white is the clear liquid (also called the albumen or the glair / glaire) contained within an egg. In chickens, it is formed from the layers of secretions of the anterior section of the hen's ...
Avidin is a tetrameric biotin -binding protein produced in the oviducts of birds, reptiles and amphibians and deposited in the whites of their eggs. Dimeric members of the avidin family are also found in some bacteria. [1] In chicken egg white, avidin makes up approximately 0.05% of total protein (approximately 1800 μg per egg).
Temperatures above or below the range that cells tend to live in will cause thermally unstable proteins to unfold or denature (this is why boiling makes an egg white turn opaque). Protein thermal stability is far from constant, however; for example, hyperthermophilic bacteria have been found that grow at temperatures as high as 122 °C, [39 ...
While eggs are already a go-to food for those looking for a satisfying, healthy breakfast, Bauer's trick for scrambled eggs will actually double the protein in the dish. Just add cottage cheese ...
After cooking, it can be considered a protein gel (depending on the length of time it was cooked). Heating high-protein food such as balut can cause the chemical changes to take place and fully or partially denature proteins, causing the surface to become thick and causing an irreversible gel protein to form.

Protein anabolism is the process by which proteins are formed from amino acids. It relies on five processes: amino acid synthesis, transcription, translation, post translational modifications, and protein folding. Proteins are made from amino acids. In humans, some amino acids can be synthesized using already existing intermediates.
Ovomucin is a glycoprotein found mainly in egg whites, as well as in the chalaza and vitelline membrane. The protein makes up around 2-4% of the protein content of egg whites; like other members of the mucin protein family, ovomucin confers gel -like properties. It is composed of two subunits, alpha-ovomucin (MUC5B) and beta-ovomucin (MUC6), of ...
