Casein doesn't have (or it is very limited) secondary or tertiary structure, rather it is linked exclusively via covalent interactions in its calcium-phosphate micelle structure. Thus, heating the milk to such temperature is insufficient to break the micelles apart and consequently the casein molecules will not denature (at a moderately high temperature of 80 degrees, such as pasteurization.
Casein has a negative charge and it is dispersed in milk, to make cheese one must denature casein to coagulate it. Using the enzyme rennin, found in rennet, the casein will coagulate.

by heating above certain temprature eg.90 or 100 degree celcius or by treting with strong alkali or strong acid you can denature your DNA *Actually, you can denature DNA in water if you wanted to. Basically any polar solvent will denature DNA because it has a negatively charged sugar-phosphate backbone. Mutagens can also influence DNA although it isn't exactly denaturing it. So can high energy light, like UV or all kinds of radiation. This, too, isn't denaturing though.
Denaturants such as urea, SDS, guanidium hydrochloridecan denature proteins. Organic solvent such as alcohol can be also used to denature proteins. A combination of reducing agent DTTor beta-mercaptoethaol with heating at 90 degrees for 5 minutes about will completely kill the three dimensional structure of proetin and make it to its primary structure.
Casein is a protein found in milk and the pancreatic digest of Casein is the breakdown of casein into Tryptone, Casitone and Trypticase. So basically it is the subunits of Casein
Protein denaturation through heating has several clinical applications. For example, in the field of oncology, hyperthermia therapy involves heating tumor tissues to denature proteins and induce cell death. In ophthalmology, laser-assisted in situ keratomileusis (LASIK) uses a laser to denature corneal proteins, reshaping the cornea to correct vision problems. Additionally, in dermatology, heat-based treatments such as radiofrequency ablation and intense pulsed light therapy can denature proteins in skin tissues to remove unwanted pigmentation or tighten the skin.
Casein is used in the body to aid in the development of muscles. There are 3 different type of Casein and they are as follows: Calcium Casein, Micellar Casein and Milk Protein.
Casein is not soluble in water.
No. Casein is a protein found in cows milk.
No, it's not Casein free, instead it is one of the 2 proteins in cow milk- Whey and Casein
