Question

Can someone help me define denature

Answer 1

It means for a protein to lose it's conformation (3D structure) and it is no longer able to serve it's function.

Answer 2

Thank you

Answer 3

no problem. Basically, when you straighten your hair (assuming you do) you're denaturing your hair.

Answer 4

Ok I got it haha

Answer 5

basically denature mens destroy the natural qualities of some thing/////but in biology,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), or heat....As protien in living cell is denatured it lost its charachteristics,,,,,may lead to cell death////When food is cooked, some of its proteins become denatured. This is why boiled eggs become hard and cooked meat becomes firm.
A classic example of denaturing in proteins comes from egg whites, which are typically largely egg albumins in water. Fresh from the eggs, egg whites are transparent and liquid. Cooking the thermally unstable whites turns them opaque, forming an interconnected solid massWhen a protein is denatured, secondary and tertiary structures are altered but the peptide bonds of the primary structure between the amino acids are left intact. Since all structural levels of the protein determines its function, the protein can no longer perform its function once it has been denatured

Answer 6

this is the shape of protien before and after denaturing of it
