role of fatty acids in the human body.
What are fatty acids?This is the carboxylic acid composition of vegetable and animal fats.They perform the function of energy, ie. A. The decay of acid produced in the body energy, as well as plastic function, because acids are involved in the construction of membranes that make up the skeleton of plant and animal cells.Absolutely all of the fatty acids are divided into saturated and unsaturated.More useful unsaturated fatty acids, ie. K. They are synthesized biologically-active substance prostaglandins play a direct role in metabolism.
Fatty acids synthesized in the liver, the intestinal wall, pulmonary and adipose tissues, the bone marrow and other tissues.Fatty acids are also included in the comp
What is called oleic acid?The role of acid in the human body.
Oleic acid - is the highest mono-unsaturated fatty acid, which is included in the composition of fats (lipids) that are involved in the construction of membranes and to the greatest extent the properties of these lipids.The process of replacing oleic acid in lipids, consisting of biological membranes, other fatty acids are extremely sharply modifies the biological membranes feature called permeability.The presence in the composition large quantities of such fatty acids in fat depots human protects lipids from oxidation with a small amount of antioxidants.
Oleic acid is in principle a nonessential fatty acid that can be synthesized, for example, cells in the human liver.However, oleic acid, all of this are some of the most common acids are fats in food.Oleic acid is of great importance in the diet of humans.Fats in which oleic acid content is increased, have a high digestibility.In medicine, even used the drug, based on oleic acid - linetol.
In industry oleic acid is used as the basis for the production of coatings, paints, varnishes, enamels, paints.It is also used as plasticizers in perfumery and its salts - in detergents.
This acid - a source of energy for the organism, just like other fatty acids.The energy released during the oxidation of oleic fatty acids after their separation from the lipid molecules under the action of pancreatic juice.Synthesis of the acids is catalyzed by a special enzyme called oxygenase, which is present in the adipose tissue and liver.
oleic acid from olive oil obtained in the course of repeated crystallization after the collapse of lipids.Quantitative and qualitative determination of oleic acid is carried out by gas-liquid chromatography.
value of oleic acid in the human diet.
in the share of animal fat oleic acid accounts for about 40% of the value of all the acids, and almost all vegetable oils - about 30%.Extremely rich in oleic acid olive oil and peanut.Oleic acid
replaceable, despite the fact that the human diet most favorable is the content that is very close to the fat content in the reserve person.That this eliminates the need to rebuild the fatty acid composition of lipids, coming from the food, which means that the waste of resources and energy in the human body will not occur.
optimum delivery oleic fatty acid is provided in compliance with food balanced nutrition formulas, in which two thirds of the human diet should be an animal fat, and a third - vegetable origin.In this case, the diet contains about 40% oleic acid.After thermal processing oils which are rich oleic acid, they are less as compared with other oils deteriorate by oxidation.That is the basis for the use of oils during frying some products from corn, potato, etc. G., As well as for pouring cans.
After hydrogenation of vegetable oil to produce fatty basis for margarines produced trans-oleic acid.This isomer, similarly as oleic acid, absorbed well by the human body, but to a lesser extent is included in the fat depot.
oleic acids are vital for proper metabolism.
