When egg whites are raw, the proteins are folded up in a compact structure, scattering light and appearing clear. When the egg white is cooked, heat causes the proteins to denature and unfold, forming a more organized, opaque structure that reflects and scatters light, making it appear white. This change in protein structure is what causes the color transformation.

What colour is egg whites and sodium hydroxide?
Egg whites are colourless and transparent until they are cooked when they become white and opaque. Sodium hydroxide is white.
What is clearly sticky liquid of egg called?
The clearly sticky liquid inside an egg is called albumen or egg white. It is clear and viscous when raw, but becomes white and opaque when cooked.
What does an egg change into when its cooked?
When an egg is cooked, the proteins in the egg white and yolk denature and coagulate, resulting in a solid structure. The texture changes from raw and slippery to firm and cooked, with the egg white becoming opaque and the yolk changing from runny to solid, depending on the cooking time.
What does coagulation mean in eggs?
Coagulation in eggs refers to the process of proteins in the egg denaturing and joining together to form a solid mass when exposed to heat, resulting in the cooked texture of eggs. This process is commonly seen when eggs are fried, boiled, or baked.
What would the reactants and products be in the reaction of cooking an egg?
The reactant in cooking an egg is the raw egg itself. Heating the egg denatures the proteins and causes them to coagulate, leading to the formation of the cooked egg. The products are the cooked egg white and yolk.
What is the difference between cooked and uncooked egg?
The difference between a cooked egg and a raw egg is that when a egg is cooked the clear/yellow gooey stuff turns white and turns into a solid. A raw egg doesn't have the white stuff because it has not been added to heat. This is an example of a chemical change.
The white of a raw egg is clear It contains the protein egg albumin When the egg is cooked the albumin changes from clear to opaque producing the white What is happening at the molecular l?
yes
How can you determine if eggs are cooked properly?
You can determine if eggs are cooked properly by checking their texture and appearance. Cooked eggs should have a firm white and a yolk that is set but still slightly runny for a soft-boiled egg, or fully cooked for a hard-boiled egg. You can also use a thermometer to ensure the internal temperature of the egg reaches at least 160F (71C) for safety.
What colour is egg whites and sodium hydroxide?
Egg whites are colourless and transparent until they are cooked when they become white and opaque. Sodium hydroxide is white.
What are pouched eggs?
eggs that are cooked different from other ones - Perhaps you mean "poached eggs," which are cooked in boiling water without the shell. The idea is that the egg-white becomes a pocket for the yolk.
What are the solid white spots inside a chicken's egg white before it is cooked?
They are call chalaza and are strands of protein that hold the egg yolk centered in the albumen. The fresher your egg is the more prominent the chalazae are and they are perfectly edible. Once cooked they are not visible and are similar to the material of the egg white. Stale eggs will have had them but they will have disappeared as the egg lost moisture.
What inference can you make about the digestibility of cooked egg white?
Cooked egg white is quite digestible.
What is clearly sticky liquid of egg called?
The clearly sticky liquid inside an egg is called albumen or egg white. It is clear and viscous when raw, but becomes white and opaque when cooked.
What are egg whites?
Egg whites are the clear liquid within an egg. Think of the contents of an egg being of two different substances....the yolk (yellow part) and egg whites (the clear parts).
What are scrambled eggs cooked in?
Egg Pan
Why does eggs change colors when heated?
Eggs change color when heated because the protein molecules aggregate and become insoluble. Normally, the white of an egg is clear because the proteins are dissolved in water. However, when the egg is cooked, these proteins aggregate, or stick to proteins around them. These agglomerated proteins block the light differently and change the color of the egg.
The clear protein of an egg white becomes opaque and firm when cooked because the heat?
it turns the protein into carbohydrates
