A acid is a substance which, in solution, causes an increase in the concentration of hydrogen ions. The acids can be combined with the bases for the development of salts. Fatty , for its part, is what has grease (sebum, lubricant).
The fatty acids are biomolecules of lipid constitution that are formed from a linear and extensive hydrocarbon chain, with a carboxyl group at its end. As you can see, it is necessary to know the meaning of several concepts to understand what fatty acids are.
These acids are biomolecules: that is, molecules that constitute living beings. The lipids On the other hand, they are those molecules that are composed mainly of hydrogen and carbon. As for the carboxy groups , are sets of compounds that have a carboxy or carboxy type functional group (they have a hydroxyl and carbonyl group on the same carbon).
The carbon atoms of fatty acids are joined through covalent bonds, whether double or single. At one end of the chain, there is an atom with three free bonds that occupy hydrogen atoms, while the rest of the atoms have two free bonds (occupied by other hydrogen atoms). At the other end, the carboxyl group appears, which is combined with any of the hydroxyl groups to generate a reaction .
The lipid bilayer of the plasma membranes of the cells is formed with these fatty acids, which belong to the groups of molecules known as glycolipids and phospholipics . In the case of mammalian animals (including at man ), fatty acids are usually found as triglycerides , which are deposited in adipose tissue.
It is important to know, in addition to all of the above, that fatty acids, if we consider what their structure is at a chemical level, can be divided into three large groups:
-The monounsaturated, mostly derived from nuts, salmon, vegetable oils such as wheat ...
-The saturated, which are fats. We can say that they can be found in foods that fundamentally have animal origin as would be the case, for example, of butter, cheese, meat ...
-The polyunsaturated, which are divided, in turn, into two sets: omega 3 fatty acids and omega 6 fatty acids.
In recent times, where there has been a notable increase in the number of people who are committed to taking care of their diet, we are faced with the fact that foods that provide omega 3 fatty acids have gained prominence. Why? Because they are considered to bring numerous benefits to the body.
Specifically, it is ruled that they favor both the correct functioning of the brain and that of the nervous system, without forgetting of course that they do the same with the immune system. That without forgetting that they significantly improve blood pressure or coagulation, among others.
Omega 6 fatty acids, on the other hand, must be ingested in an absolutely moderate way and under control. Yes, because an excess in the body of the same results in serious health problems such as atherosclerosis or even difficulties of an inflammatory nature.
