protein-based

The term is a modern scientific compound, formed in English by combining the noun 'protein' with the participial adjective 'based'. 'Protein' itself originates from the Greek prōtos (first), reflecting the 19th-century scientific view of proteins as primary and essential substances of life. 'Based' derives from the Greek basis (foundation), via Latin and French, conveying the sense of something being established upon a support. Thus, 'protein-based' logically describes any material, diet, or principle that is fundamentally established upon or derived from proteins, carrying forward the ancient concepts of primacy and foundational support into contemporary biochemical and nutritional contexts.

Structure: protein (substance) + based (founded on) - protein: From French protéine and German Protein, from Greek prōteios (primary), from prōtos (first).
