What does heat do to protien?

Answer 1

When you heat a protein it vibrates rapidly. The hydrogen bonds that hold the amino acid strand together (giving the chain its folded or helix shape) break and the protein unravels. Once unraveled, the chains then link back together, forming new bonds in a different patten. This changes the construction of the substance and therefore changes the behavior. The best example of this is to heat an egg. It changes the proteins, making stronger, permanent bonds, and causing the egg to change from clear to white and Gelatin to solid.

Answer 2

Certain proteins can physically deform during temperature changes, causing them to becoming denatured. This means they will not react correctly with other substances, because the molecule won't be "lined up right" when it collides with another reactant (at the particle level.) This is why your body runs a fever when you get sick. It's trying to kill the invading chemicals by denaturing them, so they can't replicate.

Answer 3

Heat introduces more kinetic energy and can disrupt the folding of proteins this can lead to denaturing if the confirmation changes result in loss of function in the protein.

Answer 4

heat introduces more kinetic energy and can disrupt the folding of proteins

this can lead to denaturing if the confirmation changes result in loss of function in the protein

Answer 5

When proteins are heated, their chemical structure is denatured (changed) and it cannot be reversed. Becomes less soluble and if overheated, its less digestible.

Answer 6

The right amount of heat will generally denature proteins which is essentially when they unravel. This generally makes them useless/ineffective
