diffrence between adrenaline and nor-adrenaline
Adrenaline | Noradrenaline |
Adrenaline has a methyl group attached to its nitrogen | Noradrenalin has a hydrogen atom in place of a methyl group |
Adrenaline is responsible for controlling all the body tissues | Regulates parts of the brain which are responsible for controlling the mind and body |
It has lesser affinity to bind with alpha receptors | It has a litter greater affinity to bind with alpha receptors |
It is not predictable because it has different sensitivities for alpha and beta receptors |
The effect of noradrenalin is more predictable |
Adrenaline is greater in terms of cardiac simulation leading to greater cardiac output | Cardiac simulation is less |
Constriction of blood vessels is slightly less, thereby decreases the diastolic pressure by reducing the total peripheral resistance | Noradrenaline has stronger effects on constriction of blood vessels leading to increased peripheral resistance and increased diastolic pressure |
Epinephrine is greater in terms of increasing metabolism | It is slightly lesser |
