Meaning and Definition
A denatured protein, especially one formed by the action of acids or alkalis, which is insoluble in water but soluble in dilute acids or alkalis.
A biochemical term referring to the product of protein denaturation where the protein's native structure is altered, resulting in changes to its solubility properties while retaining some protein characteristics.

FAQ
Frequently Asked Questions
No, it is an archaic term from early protein chemistry, largely replaced by more precise descriptions of denatured or hydrolyzed proteins.
Not exactly. 'Metaprotein' refers to a specific type of denatured protein—insoluble in water but soluble in dilute acid/alkali—making it a subset of the broader category.
Historically, metaproteins are the first products of acid/alkali action on proteins (insoluble), while proteoses are further degradation products that become soluble in water.
For most learners, it is not important. It is only relevant for those reading very old biochemical literature or studying the history of science.
