Purpose[ edit ] Protein purification is either preparative or analytical. Preparative purifications aim to produce a relatively large quantity of purified proteins for subsequent use. Examples include the preparation of commercial products such as enzymes e.

Uh Oh There was a problem with your submission. Please try again later.The heat-caused denaturation in albumin protein in egg whites causes the once translucent, runny substance into one that is white and firm.
Denaturation is the alteration of a protein shape through some form of external stress (for example, by applying heat, acid or alkali), in such a way that it will no longer be able to carry out.
TITLE: Heat Changes Protein Structure: Frying an Egg SOURCE: Cain, et al., Discover Biology, Third Edition, W. W. Norton & Co.
© W. W. Norton & Co. and Sumanas. Denaturation is a process in which proteins or nucleic acids lose the quaternary structure, tertiary structure, and secondary structure which is present in their native state, by 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), radiation .
Protein folding and hydration. Although the native state of a protein resides at a minimum on the potential energy surface, there is no reason to suppose that this structure is the global minimum free energy structure as its folding route is a guided, rather than random, process.
