myoglobin: the molecule is compact there is no water inside it with the exception of a very small number(less than 5) of single water molecules presumably trapped at the time the molecules is folded up.
hemoglobin: it iz 4 times larger than myoglobin. it is spherical molecule formed by 4 subunits which are identical in pairs . each subunits has a conformation closely resembling that of myoglobin and the aggregation is held together by extensive van der waals forces.
Cooperative binding. Hemoglobin can load and unload oxygen better than myoglobin. So it is kore sensitive to changes in the environment, vs. Myoglobin
The iron-containing protein found in red blood cells that carries oxygen is called hemoglobin.

Myoglobin
iron. thanks for this quick answer.
Myoglobin's function is similar to that of hemoglobin, which carries oxygen in red blood cells to various tissues. Myoglobin has even higher affinity for oxygen than hemoglobin and is specific to muscle cells. Myoglobin thus acts as a storage of oxygen, as it holds oxygen inside heart and skeletal muscles.
keratinThe correct answer is NOT keratin... the correct answer is myoglobin. This is the oxygen-binding pigment in muscle.
in myoglobin, the molecules are compacted but in haemoglobin, the molecule formed by 4 subunits which are identical in pairs. its 4 times larger than myoglobin.
1 Each myoglobin molecule has one heme group and can bind one oxygen molecule. Hemoglobin on the other hand can bind up to 4 molecules of oxygen.
heomoglobin..... a comlex compound of proteins with iron......
Myoglobin is synthesized in cells and imparts the reddish-brown color of skeletal muscle tissue. Like hemoglobin, myoglobin can combine loosely with oxygen. This ability to temporarily store oxygen reduces a muscle's requirement for a continuous blood supply during muscular contraction.
