Homework Answers
Half-Life - Half-life means the concentration of drug in the body or plasma is reduced to half.
Berberine- it is a plant extract, used for Diabetes, Hypertension, Hyperlipidemia, etc
Half-life is 4.8 hour + or - 1.4 hour
Curcumin - It's known as turmeric, an Asian spice
Half-life is 6 to 7 hour
Immunoglobin M - It is an antibody known as IgM, It is largest in size in all antibody and its first respond to infection.
Half-life is 5 to 6 days
