An explanation of the Genetic Code: DNA is a two-stranded molecule. Each strand is a polynucleotide composed of A (adenosine), T (thymidine), C (cytidine), and G (guanosine) residues polymerized by dehydration synthesis in linear chains with specific sequences.
SIDE EFFECTS. Common adverse reactions to systemically administered epinephrine include anxiety, apprehensiveness, restlessness, tremor, weakness, dizziness, sweating, palpitations, pallor, nausea and vomiting, headache, and respiratory difficulties.
Epinephrine and the skin. The effect of epinephrine on the skin is mainly caused by it binding to alpha-adrenergic receptors, the alpha-2-adrenergic receptor in particular. Restriction of the arteries is caused by the binding of epinephrine to these alpha-adrenergic receptors. This cuts off blood supply to the skin.
