(上图) 在煮熟鸡蛋的时候，在蛋清中的蛋白质白蛋白发生变性和溶解性的损失。(下图) 回形针提供一个可视化的类比来帮助概念化变性的过程。
The effects of temperature on enzyme activity. Top - increasing temperature increases the rate of reaction (Q10 coefficient). Middle - the fraction of folded and functional enzyme decreases above its denaturation temperature. Bottom - consequently, an enzyme's optimal rate of reaction is at an intermediate temperature.
Functional proteins have four levels of structural organization: 1) Primary Structure : the linear structure of amino acids in the polypeptide chain 2) Secondary Structure : hydrogen bonds between peptide group chains in an alpha helix or beta 3) Tertiary Structure : three-dimensional structure of alpha helixes and beta helixes folded 4) Quaternary Structure : three-dimensional structure of multiple polypeptides and how they fit together
Process of Denaturation: 1) Functional protein showing a quaternary structure 2) when heat is applied it alters the intramolecular bonds of the protein 3) unfolding of the polypeptides (amino acids)

变性（英语：Denaturation）在生物化学中是指蛋白质或核酸受到某些理化因素的作用，其高级结构发生破坏从而丧失生物活性的现象。

IUPAC definition

Process of partial or total alteration of the native secondary, and/or tertiary, and/or quaternary structures of proteins or nucleic acids resulting in a loss of bioactivity.

Note 1: Modified from the definition given in ref.

Note 2: Denaturation can occur when proteins and nucleic acids are subjected to elevated temperature or to extremes of pH, or to nonphysiological concentrations of salt, organic solvents, urea, or other chemical agents.
