What happens when you heat proteins?

Answer 1

it is de-natured, this is why very high fevers are potentially life threatening because the proteins in our body are de-natured causing severe damage Heating affects the secondary structure of proteins, causing changes in the shape of the molecule. An easy example would be human hair which is largely made of protein. When hair is pulled through a curling iron, it tends to become curlier because the heat is changing the secondary structure of the protein molecules that make up the hair. Of course, this change only lasts for a short time.

Answer 2

It is de-naturated or coagulated. Heating affects the secondary structure of proteins. It is like when boiling or frying an egg. (Eggs contain a lot of proteins).

When heated above boiling (frying) then proteins also decompose, react with other stuff in meat (e.g. glycogen) and get brown-crusty properties.

Answer 3

Proteins, which are made up of many amino acids, usually have complicated shapes so that they can work with other molecules, just like microscopic tools. When you heat proteins, they denature, which means that they lose their shapes and become long, useless chains of amino acids. They are still edible, though - when you eat proteins, whether or not they've been heated, your body breaks them down into amino acids and remakes them into new proteins.

Answer 4

When a protein is heated too much, it is denatured and loses its native conformation. This conformational change can significantly change the properties of the protein. For instance, denatured enzymes will lose their catalytic function.

Answer 5

If you understand the lock and key model of enzymes, then this will make sense as to why this is important. Enzymes are proteins. If they lose their specific shape, then they will no longer be able to function. This is why a prolonged fever is so dangerous and can be deadly for small children and the elderly.

Answer 6

you die

then go to heaven if you have a faith in the Lord almighty :)

AMEN

Answer 7

It coagulates, like when boiling or frying an egg. (Eggs contain a lot of proteins.)

Answer 8

as long you dont heat it up very high then it become OVERCOOKED.If you heat it up just the right time its fine.
