Denaturing albumin 'egg white' with copper 'egg white' is the common name for the clear liquid contained within an egg it is also called the albumen or the glair/glaire when cooked, the albumin turns white and opaque it is said to have been denatured. Egg white tends to thin out as an egg ages because its protein changes in character the cloudy appearance comes from carbon dioxide as the egg ages, carbon dioxide escapes, so the albumen of older eggs is more transparent than that of fresher eggs. Denaturation is a process in which proteins lose their shape and, therefore, their function because of changes in ph or the heat from a pan denatures the albumin protein in the liquid egg white and it becomes insoluble the protein in meat also denatures and.
