Quattuor structurae proteinorum: structura primaria, secundaria (vel lamina vel helix), tertiaria, quaternaria.

Proteinum^[1] vel polypeptidum est quodlibet ex permultis compositis organicis molecularum polymericarum acidorum aminicorum (F.Ch.: H3N-CH-COO-) modo quinquaginta (et plura quaelibet) vinculis peptidicis confectis.

Vinculum peptidicum oritur, cum radicalis hydrogenicus aminicus (-H) se radicali hydroxyllico (OH) aquam excludens iungit; vide figuram infra.

      H     O  H   R'   O
      |    //  |   |   //
H3N - C -  C - N - C - C - O + H2O        
      |            |
      R            H

Proteina in cellulis duobus muneribus (structuralibus agentibusve catalyticis) funguntur. Quamobrem maxime necessaria sunt proteina vitae. Varietas proteinorum est ex ordine radicalium aminicorum in catena peptidica, et quantitate uniuscuiusque horum radicalium. Ergo, omnis cellula suo RNA et DNA utitur ut bene suas res gerat et DNA duplicationis vi se perpetuet.

De origine nominis

Proteinum est forma Latina deducta ex vocabulo Francogallico protéine a G. J. Mulder ficto. Praecepit enim Mulder Graecum adiectivum, q.e. πρωτεῖος 'primarius', huic vocabulo subesse.^[2]
