Proteins are huge molecules that need to get an accurate tridimensional structure to accomplish their function.
In water, these molecules keep their hydrophilic parts in the outside and the hydrophobic part in the inside.
There are some treatments like changes in temperature or pH that provoke changes in the tridimensional structure of the protein. This process is known as DENATURATION. The protein losses its original native structure and its properties.
When denaturation occurs the protein tends to join together with other denaturalized proteins through the areas that repeal water, becoming coagulated.
Denaturation occurs when there is a disruption in the highly ordered or molecular structures, i.e, the secondary and tertiary structures ,present in the native state of the protein.
Denaturation can be caused through the application of some external stress, heat, inorganic salts among others.
In the cardiovascular cycle, the autonomous withdrawal and unwinding of heart cells are facilitated through the movement of the heart's characteristic conduction framework and by cell-to-cell correspondence by means of the hole intersections in the myocardial cells themselves.
The natural conduction arrangement of the heart comprises of nodal tissue, whose specific cells have both apprehensive and solid qualities. Nodal tissue is restricted in explicit areas of the heart.
