[QUOTE="KevinPotts, post: 1200005, member: 290458"] Chapter 7: Liquid Oils & UNsaturated Fatty Acids The author kicks off by saying the fats that heal contain UnSAT Fat Acids (UFAs) which makes them liquid oils. UFAs differ from SAFAs in only one respect, namely they contain one or more double bonds between carbon atoms in their fatty carbon chain. And for each double bond they have upto 2 hydrogen atoms. Aside from this they are identical:) Like SAFs they have a methyl end and an acid end and carbon chains of varying lengths. Properties of the Double Bonds: The small difference in structure (double bond) DRASTICALLY changes an UFAs properties. SAFAs and Trans-fatty acids look like straight bodied caterpillars, UFAs look like bent caterpillars. This so called Cis-configuration and kink in the molecule makes them difficult to align and this UFAs aggregate poorly and melt at low temps (are more liquid) than SAFAs. MUFAs (Monounsaturated F As): Unseats with just one double bond. Shortest are 10-carbon chains. C22 and C25 also found, appearing in small quantities in milk. But 12 & 14 are of minor importance nutritionally. More important is a MUFA with C-16 and double bond between 7 & 8. It is called Palmitoleic Acid and occurs in large quantities in milk., coconut and palm oils. An excess he states of this MUFA can lead to health probs due to chemical conversion into hormone-like prostaglandins. Most important MUFA has 18-carbon chain with double bond at 9 and 10 and is called Oleic acid. Found in Olive, almond, cashew, macadamia, peanut, pistachio, pecan, canola, avocado, hazelnut, membranes of plants and animal cell structures, and fat deposits of most land animals. OA's fluidity (melts at 15c) helps keep our arteries supple. I found this a fascinating piece of info. It also resists damage by oxygen and is fairly stable. OA is THe major fatty acid found in the oils from our sweat glands. Our body can also make it from Saturated Fatty Acids. UNSAT Fat Acids with More Than One Double Bond: Our author thinks these are the most interesting UNSats. Most important contain 28- carbon atoms and two of these are known as EFAs ( Essential Fatty Acids). Very important in nutrition & vital to health. First is called Linoleic Acid - often referred to as polyunsaturated. Members of this w6 group also include Gamma-Linoleic acid found in borage, hemp and evening primrose oil. The second w3 EFA called Alpha-Linoleic acid has three double bonds. It is referred to as SUPERunSaturated to distinguish it and it's family from poly w6 family mentioned first. W3 UFAs include EPA, and DHA BOTH found in fish oils. These families are commonly called Omega 6 and 3s:) Natural & Unnatural: W6 polyunsaturated are shortened to PUFAs. Natural w6 are vital to health but there are also NON-natural man-made w6 which interfere with biological functions. The same is true for w3 SUPERunSats. Again they can be made toxic with artefacts in processing. In the western diet we struggle to get a balanced ratio of omega 6 and 3s and need to work harder to take in w3. Converts: Our body converts EFAs to longer more highly UNSats with important functions in brain cells, nerve endings, sense organs, adrenal glands, sex glands, and ALL cells. Some of these EFAs can be supplied by plant seeds, seed oils, fish and marine animals. I found the whole section on Oleic Acid as a MUFA so fascinating:) Sent from my iPhone using [url=https://siteowners.tapatalk.com/byo/displayAndDownloadByoApp?rid=67]DCUK Forum[/url] [/QUOTE]
