What is Yellow color of a bruise is due to which of the following? and explain in detail?
The yellow color is due to degradation of hemoglobin to bilirubin. Deoxyhemoglobin is responsible for bluish bruise seen on the first day after the injury. Bruises change color over time, because of the degradation of haemoglobin in the blood.
