Basically it binds with oxygen to form oxymyoglobin. when muscles are excercising excessively oxymyoglobin splits and the oxygen is released into the blood to fuel the muscles by assisting in the production of ATP.
The main function of myoglobin is to carry oxygen to muscle tissues that have been damaged. Myoglobin is only found in a muscle injury.

∙ 16y agoMyoglobin is related to hemoglobin and it is an iron and oxygen protein that can be found in the mammal muscle tissues. Its functions will be depends on its structure such as if iron is greater than oxygen or vice versa or they are equal.

Like haemoglobin which are the oxygen carrying pigments in red blood, myoglobin take up and subsequently store oxygen that it releases when muscle tissues need oxygen in order to sustain contraction.
In animals, diving mammals like seals or whales posses muscles with high abundance of myoglobin because it is the principle oxygen carrying pigment of muscle tissues and high concentrations of myoglobin in muscle cells allow organisms to hold their breath for a longer period of time. Hence diving mammals such as whales and seals have muscles with particularly high abundance of myoglobin.
The existence of myoglobin in human urine is termed myoglobinuria and can be problematic for human health. Slight myoglobinuria can happen in people when taking prolonged vigorous exercise. It is also important in human medicine because severe myoglobinuria is usually due to the release of myoglobin from a large region of damaged muscle, such as happens in crush syndrome, and that can lead to kidney failure.

It holds a reserve supply of oxygen in muscle cells.

How myoglobin is Distributed in cardiac disorders?
myoglobin
What the primary structure of myoglobin?
The amino-acid secquence of myoglobin is the primary structure.
What is irons main function in the body?
hemoglobin and myoglobin are 2 types of iron in the human body.
Why hemoglobin is better long distance oxygen transporter than myoglobin?
Both Myoglobin and Haemoglobin binds to oxygen, but they differ in many aspects. Usual site: Myoglobin: muscle tissues Haemoblogin: red blood cells (whole body) Main function: Myoglobin: stores oxygen (in muscle tissues) Haemoglobin: Oxygenation of tissues (whole body) Waste (CO2) collection (whole body) gas exchange (lungs, tissues) Oxygen carrying capacity: Myoglobin: monomeric = one heme prosthetic group, one iron atom Haemoglobin: tetrameric = four heme prosthetic groups, four iron atoms. Structure Myoglobin: secondary and tertiary, no allosteric interaction Haemoglobin: quaternary structure, allosteric interaction, different affinity Affinity to oxygen Myoglobin: Oxidation (Fe2+ → Fe3+) prevents oxygen binding. Haemoglobin: requirement specific affinity: (gradually increasing in the lungs, . gradually decreasing at the tissues) Prefered binding Myoglobin: Carbon monoxide preferred to Oxygen. Haemoglobin: Oxygen, carbon dioxide While in cases of hugely increased demand, myoglobin releases oxygen for metabolism, but, in the long run haemoglobin is more suitable for the purpose.
Does Myoglobin have a primary structure?
No, it has a tertiary structure.
What does myoglobin do for muscles?
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.
How myoglobin is Distributed in cardiac disorders?
myoglobin
What compound stored oxygen inside skeletal muscle cells?
keratinThe correct answer is NOT keratin... the correct answer is myoglobin. This is the oxygen-binding pigment in muscle.
What the primary structure of myoglobin?
The amino-acid secquence of myoglobin is the primary structure.
What is nitric oxide myoglobin?
When myoglobin is reduced by nitric oxide through the curing process.
What is irons main function in the body?
hemoglobin and myoglobin are 2 types of iron in the human body.
What is a myoglobin test?
Myoglobin is a protein found in muscle. Myoglobin tests are done to evaluate a person who has symptoms of a heart attack (myocardial infarction) or other muscle damage.
What is the difference between haemoglobin and myoglobin?
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.
Is myoglobin an enzyme?
No.
What is the effect of a high myoglobin on the heart muscle?
A high myoglobin means that the heart muscle has been broken down. It can also mean that a heart attack happened. Myoglobin is a protein that can be found in the heart muscle.
One advantage hemoglobin has over myoglobin as a respiratory pigment is that?
Cooperative binding. Hemoglobin can load and unload oxygen better than myoglobin. So it is kore sensitive to changes in the environment, vs. Myoglobin
