Flashcards in functional properties Deck (4)
proteins - explain denaturing
Denaturation is when the structure of the protein breaks apart --> Peptide bonds come apart.
- It is not easy to observe as a chemical change occurs instead of physical.
proteins denaturing E.G.
Salt helps keeps the meat moist.
proteins - explain coagulation
Heat, acids and enzymes can cause the separated strands of amino acids in the denatured protein to regroup with new cross bonds.
If coagulation continues for too long, over coagulation will occur, where the proteins shrink and toughen forcing liquids out from inside the protein. It is irreversible e.g. when you overbeat egg whites it reverts back to runny mass. This is called syneresis.
