Fatty acids can be defined as carboxylic acids with long aliphatic chains that can either be branched or unbranched. The fatty acids that occur naturally, possess carbon atoms in even numbers and are usually unbranched. Fatty acids are major components of lipids; they exist in three main forms of esters: phospholipids, triglycerides and cholesteryl esters.

Even and Odd Chain Fatty Acids
Most naturally occuring fatty acids have an even number of carbons in their aliphatic chain. Example: oleic acid (18), stearic acid (18). However, some fatty acids also have an odd number of carbons in their chain. They are known as odd-chain fatty acids (OCFA). Example: heptadecanoic and pentadecanoic acid that are found in dairy products. The biosynthesis of odd chain fatty acids is a little more complex than the even chain fatty acids.

Saturated and Unsaturated Fatty Acids
The acids that have no double bond (C=C) in their aliphatic chain are known as saturated fatty acids. The chemical formula of saturated fatty acids can be written as CH3(CH2)nCOOH. Below is a table of common saturated fatty acids with their formula. The unsaturated fatty acids possess at least one double bond in their aliphatic chain. The double bond in the molecule can generate two isomers for unsaturated fatty acids: cis and trans configurations.

Acidity
Fatty acids have similar acidities. As the chain length of a fatty acid increases, their solubility in water decreases, posing no or little effect on the pH of the aqueous solution. Example: Nonanoic acid (C9) has a pKa of 4.96 whereas acetic acid (C2) has a pKa of 4.76.

Hydrogenation
Unsaturated fatty acids are prone to get rancid (autoxidation or hydrolysis of fats when exposed to air). Therefore the unsaturated fatty acids undergo hydrogenation to minimise this problem.

Autoxidation
Unsaturated fatty acids undergo a chemical change in the presence of air and trace metals called autoxidation. Treatment with chelating agents can prevent this action as they remove the metal catalysts.

Ozonolysis
Unsaturated fatty acids have high chances to get degraded by ozone.

Saturated fatty acids are primarily found in red meats such as beef and pork, full-fat dairy products such as milk, yogurt, and cheese, butter, lard, shortening, palm, and coconut oils. Processed foods are also a source of saturated fat1.

Monounsaturated fatty acids are highest in peanuts, avocadoes, non-hydrogenated margarine, and oils such as olive, canola, peanut, sunflower, and safflower1.

Omega-3 polyunsaturated fatty acids can be found in flax, chia, and hemp seeds, walnuts, canola oil, and fatty fish such as salmon, herring, mackerel, and trout1.

Omega-6 polyunsaturated fatty acids are found most abundantly in vegetable oils such as soybean, sunflower, and safflower, as well as in nuts, seeds, grains and non-hydrogenated margarine1.

Being mindful of having a balanced and varied diet can help to ensure you are including sources of both saturated and unsaturated fats while emphasizing more whole foods that offer omega-3 and omega-6 fatty acids.

As a quick recap of the different sources of omega-3 fatty acids, there are three different types: ALA, EPA, and DHA. ALA is primarily found in plant foods, such as walnuts, flax, hemp, and chia seeds, soybeans, and all of the above’s oils. EPA and DHA are higher in animal foods, notably fatty fish, as well as in kelp and seaweed. Having sources of all three of these fatty acids is important for optimizing our health.

In general, it is recommended that 20-35% of our daily calories come from fat. Therefore, the recommended intake for everyone is variable. Each gram of fat equates to 9 calories, therefore for the average person who is consuming 2000 calories, it would be recommended to eat between 45-75 grams or 400-700 calories from fat daily on average.

While the recommendation for dietary fat intake is variable, there are more specific recommendations around the essential fatty acids, omega-3 and omega-6. In our culture, it not uncommon to have ample omega-6 in our diet, while omega-3 can fall to the wayside and end up being under-consumed. When we over-consume omega-6 and under-consume omega-3 we are shifting the optimal ratio of these fats and reducing the protective effects that they can have on our health.

Research4,5 suggests that the ideal omega-6 to omega-3 ratio in our diet is between 1:1 to 4:1. Despite this, it is estimated that on average the North American diet ratio of essential fatty acids is closer to 10:1-20:14! This is likely because that processed foods have increased, elevating the amount of omega-6’s being consumed from vegetable oils. This skewed ratio is thought to be tied to the increased prevalence of inflammatory diseases such as rheumatoid arthritis, irritable bowel disease, and cancers, as well as fatty liver and cardiovascular disease4.

Our corporation was established in 1988 and it's a large-scale private enterprise specializing in production, processing, research and development of soybean oil chemicals. With a history of 30 years on oil industry from 1988 to 2018, it enjoys great reputation in the industry. With business increase of the enterprise and its increase in market share it prossesses, we established a new morden garden-type factory at Dalian chemical garden with the investment capital of RMB100,000,000.- in 2007. The new factory covers are area of 77,000m2 and has almost 200 employees.
