Document Summary
Explain the difference (in structure, food sources and on health) between saturated, unsaturated, and trans fat . Explain the effects of processing on unsaturated fats lomoar cp sd. Palmitic acid found in palm oil and coca butter bonds and is saturated saturated has 4 carbon atoms, single bonds and is has 18 carbon atoms, single bonds and is has 16 atoms, single. Oleic acid found in olive oil and canola oil has 18 carbon atoms, one double bond and is unsaturated (monounsaturated) Linoleic acid has 18 carbons and 2 double bonds. It is found in most foods especially oilseeds such as canola and soybean. Linolenic acid also has 18 carbon atoms but contains 3 double bonds and is found mostly in soybean and hempseed. Linoleic and linolenic acids are essential fatty acids which we will look at in greater detail. Unsaturated fatty acids can be found in both cis and trans form, dependent on their structure at the double bond.
