What is the reaction of denature albumin with lemon juice?

When albumin is denatured, its proteins unfold and lose their natural structure, which can be triggered by acidic substances like lemon juice. The citric acid in lemon juice causes the proteins to coagulate, resulting in a solid or semi-solid texture. This reaction is often observed when cooking eggs, where the addition of lemon juice can enhance firmness or create a desired consistency in dishes. Overall, the acidity of lemon juice effectively alters the structure of denatured albumin.
