Lipid Biochemistry

FATTY ACIDS
Fatty acids are long-chain "carboxylic" acids, ie, hydrocarbons (Alkyl) chains containing the terminal-COOH chemical group. (Fig. 2)

Fatty acids containing from 4-22 carbon atoms. They can be saturated, with no double bonds in the carbon chain, mono-unsaturated double bond in the chain, or polyunsaturated with several double bonds in the fatty acid.

In nature, triglycerides occur linked (esterified) with glycerol as both are called glycerides. Fats are called If solid, if the liquid called oil. A combination of fatty acids (esterified) to glycerol is a monoglyceride, diglycerides is a combined two and three attached to the glycerol backbone (the possible) is a triglyceride.

Saturated fat (Eg, palmitic and stearic) exclusively as the 1 and 3 positions while unsaturated fatty acids can be distributed randomly among the three positions the backbone of glycerol. A common configuration is thus a saturated fat in positions 1 and 3 and one of the unsaturated fatty acids in position 2. (Fig. 3)

Fatty acids containing less than 16 carbon atoms, and saturated fatty acids, are largely oxidized to provide energy. Those containing 16-22 carbon atoms can also be oxidized for energy, but they can also be incorporated into cell membranes, regulate metabolism after conversion of eicosanoids (prostaglandins, thromboxanes, leukotrienes, lipoxins, and various other hydroxy analogs discussed below) has changed to other fatty acids, or stored in fat (adipose tissue) tissues.

NOMENCLATURE
Abbreviated notations simplify the nomenclature of fatty acids. In the case of linoleic acid (LA abbreviated notation 18:02 w6). The 18 means that the molecule has 18 carbon atoms, 2 means there are two double bonds in the molecule and w6 means the first double bond begins with the sixth carbon atom counting from the methyl (CH3), omega (w) end of the carbon chain. (Omega is designated in many publications as a small case "n" instead of "W.") The other end of the chain, the carboxyl, which is called the triangle (?) Final. (Fig. 4)

The double bonds in the nutritionally important fatty acids are separated by methylene groups (CH2). Therefore, the second double bond in Los Angeles should begin with the ninth carbon atom. Fatty acids are common detailed in Figure 5.

PHOSPHOLIPIDS
Fatty acids with 16 and l8 carbon chains can participate in the production of phospholipids, which are major structural components cell membranes. Phospholipids are similar to triglycerides in that fatty acid molecules bind to a glycerol molecule, a three carbon alcohol (Or, less commonly, sphingosine, a more complex amino alcohol). In triglycerides, all three esterified positions of glycerol in a molecule are occupied by a fatty acid. In a phospholipid, only two are so busy and the third is esterified with phosphoric acid, which in turn may have other compounds attributed such as choline, serine, glycerol, inositol or ethanolamine. Lecithin, phospholipids best known, has choline phosphate and is attached to the so-called phosphatidylcholine. If only phosphoric acid is attached, the compound is called a phosphotidate. Many molecular variations are also possible by mixing various fatty acids in the glycerol backbone. (Fig. 6)

ISOMERS
Figure 7 shows the biochemically important cis-and trans-form of fatty acids. Notice in the cis-form the hydrogen atoms of adjacent carbons the double bond are on the same side of the molecule.
The repulsive forces between these "full" hydrogen atoms, unsaturated fatty acids cause assume particular, non-linear forms that play an important role in shaping lipid membrane fluidity, and biochemical reactions involving enzymes.

In the form of trans-fatty acids, hydrogen atoms are on opposite sides of the molecule and repulsive forces cancel each other, and therefore the molecule is bent. Although the trans-form is more stable, its chemical properties and biological functions are altered. (Figs. 7 and

Biological membranes
A biological (plasma) membrane surrounds all cells within the tissue, and extends the organelles in the cytoplasm. To help visualize the size, if the size of the bacteria, the cells would be the size of a large auditorium. (In actual size, fit billion cells in a cubic centimeter). This cell "Auditorium" is with a skin of only two molecules thick. The drawings of various biochemicals that appear in these pages, therefore, be what it appears from our size as bacteria, or as a bacteria-sized person would see through a magnifying glass.

The membrane is not a static bag, but a group of chemicals with gates and pumps control chemical and ionic balances, receivers of stimuli and signal generators. It is mainly composed of phospholipids, proteins, glycolipids and cholesterol, all of which, of course, come directly from food or synthesized in situ by food components after they have been broken down by digestion.

membrane lipids are amphipathic in that they contain both a polar hydrophilic end and a nonpolar hydrophobic end. The phospholipids are oriented in a double layer sheet membranes with hydrophilic ends pointed outward and the hydrophobic hydrocarbon tails pointing inward. These properties make salts of fatty acids an important functional component of soaps since their fat soluble hydrophobic ends attract "fatty dirt" and their hydrophilic ends soluble in water can attract "Dirty liquid."

The neck of a fatty acid is at the carboxyl side of the delta and is stiff. The portion of the tail along the omega end, if they contain cis-double bonds, is very active, oscillating at a million vibrations per second. (Figs. 8 and 9)

Lipids, proteins and some within the membranes, are also in constant lateral movement. In a bacterium, a single phospholipid travel from one extreme to another in a second. Thus, the membranes are in effect two-dimensional solutions of a series of oriented molecules.
Although membranes are considered bilayers lipid, almost 50% of the membrane is composed of protein which serves many physiological functions. The sugar residues of glycolipids (sphingosine + sugar + Fatty acid, such as sphingomyelin) and glycoproteins (sugars attached to membrane proteins) are protruding into the outer surface of the membranes. Cholesterol, as well as the length of the tails of fatty acids and their degree of saturation, affects the membrane fluidity. Cholesterol inserted between the membrane fatty acids prevents crystallization. (Fig. 10)

The configuration of the territory and the discontinuity of essential fatty acids pennit electronegative links with groups of proteins in the membranes sulfhydral to form pi electron quantum mechanical membrane potentials affect the transport of oxygen in the tissues. It is also in the lipid membranes of mitochondria cellular respiration energy is produced and is packaged for use throughout the body. Thus, dietary fatty acids, which ultimately building all membranes, affects nutrient burning fuels – the most fundamental properties of life energy.

classical artistic biological membranes are too simplistic and create an impression of static barriers. Similarly, a photograph of a rocket into space striatum says nothing about of actual movement, speed or the bustle of activity that occurs within it.

The real biological membrane, containing millions of lines of fatty acids vibrating at millions of times per second, with deletions and substitutions in constant progress and biochemical doors opening and closing selectively allowing the passage of food and Waste is a dynamic, action rather than structure and literally beyond comprehension. This can be described in words, such as infinite but not fully understood rationally.

When one considers that fatty acids constitute the structure of the membrane of all cells and organelles closed the extent of their importance begins to emerge. Membrane fatty acids are indeed the guardians of life.

The dynamic and complex issues: chemistry fatty acids help to understand the nutrition in a more level. Percentage of fat in a food label has no value in determining the health of a product. Are saturated and unsaturated fats? If unsaturated, which are the proportions of omega 9-6 to 3? Have been hydrogenated fats? If so, What are the potentially toxic levels of trans isomers? Are oxidized lipids or complexed with other nutrients such as proteins? Does the product contains nutrients that are associated with lipids in their natural context, such as antioxidants, certain vitamins and minerals? What is the stability when subjected while, heat, light and air?
