Apamin increases cortisol production in the adrenal gland Adolapin,[3] contributing 2–5% of the peptides Phospholipase A2 amounts to 10–12% of peptides. Phospholipase A2 activates arachidonic acid which is metabolized in the cyclooxygenase-cycle to form prostaglandins Hyaluronidase contributes 1–3% of peptides Histamine contributing 0.5–2% and is involved in the allergic response Dopamine and noradrenaline which contribute 1–2% Protease-inhibitors contribute 2% Tertiapin
