Assignment Help:

Explain about the primary protein derivatives?

a) Proteins: These are the insoluble products which result from the incipient action of very dilute acids or enzymes. e.g. casein (curdled milk), fibrin (coagulated fibrinogen).

b) Meta proteins: Proteins resulting from the action of acids and alksllis whereby the molecule is sufficiently altered to form proteins soluble in weak acids and alkalis, but insoluble in neutral solvents.

c) Coagulated Proteins: Insoluble proteins which result from the action of heat on protein solutions or the action of alcohol on the protein. e.g. cooked egg albumin or egg albumin precipitated by alcohol.
