Resembling or having the characteristics of albumen, the protein-rich clear liquid from egg whites.
From 'albumen' (egg white protein) plus the suffix '-oid' meaning 'resembling.' The term originated to describe protein-like substances chemically similar to egg white proteins.
The '-oid' suffix literally means 'like' but not identical—so albumenoid substances copy albumen's properties but might not be actual egg protein, which is how scientists describe nature's look-alikes.
