Myoglobin and blood water can be distinguished from each other in terms of composition and color. 1. Composition: myoglobin is mainly located in human muscle cells, such as skeletal muscle, heart muscle, etc., it is a kind of intracellular protein; whereas blood water mainly contains some components of blood, which is mainly composed of a large number of red blood cells and other cells and other components. 2. Color: muscle cells are rich in myoglobin, so the human body’s muscles will show brown-red, if the muscle cells are damaged, myoglobin will be released into the blood, at this time can be detected from the blood myoglobin; and blood because of a large number of red blood cells, and red blood cells carry a large amount of oxygen, so trauma occurs in the blood oozing, the color is bright red. It is not recommended to differentiate between the two on your own, but to seek medical attention if you feel unwell.
