In some cases, our muscles do not have enough oxygen to breakdown glycogen into glucose for the synthesis of energy molecules which is known as ATP, at this time lactic acid gets accumulated in a certain area where enough oxygen is not available which is often referred to as anaerobic metabolic process.

When lactate gets accumulated it leaves to formation of lactic acidosis.

It may also upgrade at the times of heart attack, sudden shock, and at the cases of lung diseases.

Lactic acid forms in many varieties at each area according to their nature.

When they are being accumulated at muscles and blood tissues they are known as dextrorotary form.

The lactate which is obtained as a result of sucrose formation is known as levorotary form, when the same lactate if produced by bacteria during fermentation they are known as racemic form.

Thus, each of its form has its origin from the process of their accumulation or synthesis.

To explain in detail about how our body produces lactic acid, as said earlier lactic acid gets accumulate in our body when we perform heavy works or exercises during a sudden period of time.

This because when we perform powerful activities, we take a long and faster breathes which leads to the usage of more oxygen by the muscles, which tend to perform that action, which results in synthesizing energy anaerobically.

We generally get energy by the process of glycolysis, where glucose is reduced to pyruvic acid and release of ATP molecules occurs through further process which is important for the energy source.

This is a general process, but when our muscles are in a state with absence or lack of oxygen the pyruvate which is produced through a process of glycolysis convert itself into a substance namely lactate and supplies energy in the anaerobic form which leads to the accumulation of lactate at higher levels.

But this is performed by our body, for a longer time it leads to side effects by the accumulation of lactate at higher levels in the tissues which also disrupts the other metabolic activities of the muscle and creates an acidic environment around the muscle cells.

So, it results in degrading a working capability of the muscle and cannot perform any heavy or powerful activities further.

But on considering an immune response of our body, natural immune barriers prevent the muscle tissues from permanent damage and initiates the cells to work normally by upcoming the situation and by performing regular muscle contraction improves the lactic acid accumulation.

This is because our body gets slow during these conditions and allows the reverse mechanism of conversion of lactate into pyruvate and normal aerobic respiration is followed by the tissues.
