"There is hydrogen sulfide in the egg white, and that combines with iron sulfide that's in the egg yolk. So as you heat an egg, the proteins break down and they start to release sulfur gases ...
In the absence of oxygen, sulfur-reducing and sulfate-reducing bacteria derive energy from oxidizing hydrogen or organic molecules by reducing elemental sulfur or sulfate to hydrogen sulfide. Other bacteria liberate hydrogen sulfide from sulfur-containing amino acids; this gives rise to the odor of rotten eggs and contributes to the odor of ...
When eggs are cooked for a long time, the yolk's surface may turn green. This color change is due to iron(II) sulfide, which forms as iron from the yolk reacts with hydrogen sulfide released from the egg white by the heat. [3] This reaction occurs more rapidly in older eggs as the whites are more alkaline. [4]

There are a few other ingredients you'll commonly see called for being brought to room temperature before adding them into a baking recipe: Butter, cream cheese, and "liquid" dairy products such ...
Eggs contain multiple proteins that gel at different temperatures within the yolk and the white, and the temperature determines the gelling time. Egg yolk becomes a gel, or solidifies, between 61 and 70 °C (142 and 158 °F). Egg white gels at different temperatures: 60 to 73 °C (140 to 163 °F).
The U.S. Food and Drug Administration (FDA) now classifies eggs as a “healthy, nutrient-dense" food, according to a new proposed rule. Registered dietitians react to the change.
