Lipids are a part of the diet of all people, particularly the part that usually comes given by fats , which along with carbohydrates represents the largest source of energy for the body.
The lipids are organic molecules that are mainly composed of carbon and hydrogen, and having the main characteristic insoluble in water but soluble in other be organic compounds such as benzene and chloroform.
What role do they play?
In this sense, it can be said that the main function of lipids is energy , since they constitute a very good way to store energy: their caloric content is 10 kilocalories per gram.
However, lipids also have a function within the body as a reservoir of water , since they have a greater degree of reduction than in carbohydrates.
On the other hand, the storage of heat also has to do with lipids, as well as various structural, informative or catalytic functions of the body.
Lipid and fat classification
The most common classification of lipids is between saponifiable and non-saponifiable : the former are synthesized in organisms from the successive apposition of units of two carbon atoms, while the latter are synthesized from a basic unit of five carbon atoms.
In the group of saponifiable are fatty acids, which in turn tend to be classified between saturated and unsaturated. The saturated fats are those which have an animal origin, while the fat unsaturated are those arising from vegetables, and have a healthier by replacing saturated use.
Participation in diet and excesses
For the feeding of people, it is recommended that fats provide between twenty and thirty percent of daily energy needs.
However, the body does not make equal use of all types of fat, so it is better to say that the body must have ten percent saturated fat , five percent unsaturated fat and five percent polyunsaturated fat .
If you consume a greater amount of fat than recommended, it is most likely that the supplement with the consumption of other nutrients will end up leading to the recommended calorie limit. If, on the other hand, what happens is an excess in the consumption of saturated fats , what increases is the risk of suffering cardiovascular diseases .
On the other hand, there are several diseases that can appear due to the storage of lipids in some cells and tissues of the body .
The most common is Gaucher disease , which is caused by a deficiency in the enzyme glucocerebrosidase, and also affects men and women. Other diseases of this type are those of Niemann-Pick, Fabbry or gangliosidosis .
All these diseases are hereditary , as parents carry a defective gene that regulates a particular protein in a class of body cells . Although the treatment of these diseases in many cases is not yet available, an enzyme replacement therapy , or blood transfusions , is usually used .
The following list WITH EXAMPLES OF LIPIDS also includes foods that largely contain lipids:
|Olive oil||Omega 6 fats|
|Omega 3 fats||Gel|
|Canola seeds||LDL cholesterol|
|Canola oil||Phosphatidic acid|
