One trypsin unit will produce a ΔA253 of 0.001 per min with BAEE as substrate at pH 7.6 at 25 °C; reaction volume 3.2 ml, 1 cm light path.
Analysis Note
One mg will inhibit 0.9-1.3 mg of trypsin with activity of approx. 10,000 BAEE units per mg protein or 0.4-1.0 mg of α-chymotrypsin with activity of approx. 40 BTEE units per mg protein.
General description
Ovomucoid or trypsin inhibitor is an abundant protein in most avian egg whites. Three tandem domains are each homologous with pancreatic trypsin inhibitor. It is highly immunogenic, and probably accounts for most cases of egg allergy.

Serum proteins [molecular weight (MW) > 10,000] are essential for increased insulin-stimulated glucose transport after in vitro muscle contractions. We investigated the role of the kallikrein-kininogen system, including bradykinin, which is derived from kallikrein (MW > 10,000)-catalyzed degradation of serum
