There are a number of lipids that are found in foods and contribute to various functions in the body. Triglycerides are the most common lipid found in food and in the body; they consist of a <u><em>Glycerol</em></u><u> </u>backbone attached to three fatty acids.
Fatty acids are classified based on the degree to which the carbon chain is saturated with <u><em>Hydrogen</em></u>
A fatty acid is <u><em>saturated </em></u>if it contains no carbon-carbon double bonds, <em><u>polyunsaturated </u></em>if it contains two or more carbon-carbon double bonds, and<em><u> monounsaturated </u></em>if it has only one carbon-carbon double bond.
The unsaturated fatty acids can exist in one of two structural forms: the <em><u>trans </u></em>form occurs when hydrogens on both carbons forming the double bond lie on opposite sides of that bond.
When hydrogens on an unsaturated fatty acid lie on the same side of the carbon-carbon double bond, a <u><em>cis </em></u>formation exists.
An endangered species is a type of species in which this type of organism has decreasing numbers and are dangerously close to going extinct. Invasive species are species in which an organism invades an environment where it is not native to, and take over the ecosystem. Local species are species in which the organism is native to that environment and plays a key role in that ecosystem. A keystone species is a species in which the organism is a key part of that ecosystem to thrive; without it, the ecosystem would collapse
