(March 2009). The oxygenâhemoglobin dissociation curve, also called the oxyhemoglobin dissociation curve or oxygen dissociation curve (ODC), is a curve that plots the proportion of hemoglobin in its saturated (oxygen-laden) form on the vertical axis against the prevailing oxygen tension on the horizontal axis.n its most simple form, the oxyhemoglobin dissociation curve describes the relation between the partial pressure of oxygen (x axis) and the oxygen saturation (y axis). Hemoglobin's affinity for oxygen increases as successive molecules of oxygen bind.
However oxygen is not very soluble in water, and so in order for animals to convey oxygen from the lungs (or gills) to the muscles they needed to evolve an efficient oxygen-carrying molecule. In vertebrates, these molecules are the proteins myoglobin and hemoglobin. Red blood cells (above) contain hemoglobin.Blood is bright red (left), due the presence of oxy-hemoglobin. Hemoglobin (or haemoglobin, frequently abbreviated as Hb), which is contained in red blood cells, serves as the oxygen carrier in blood.owever oxygen is not very soluble in water, and so in order for animals to convey oxygen from the lungs (or gills) to the muscles they needed to evolve an efficient oxygen-carrying molecule.
