Related to polyunsaturated: polyunsaturated fatty acids

polyunsaturated

 [pol″e-un-sach´er-a-ted]
denoting a fatty acid, e.g., linoleic acid, having more than one double bond in its hydrocarbon chain.

polyunsaturated

/poly·un·sat·u·rat·ed/ (-un-sach´er-āt-ed) denoting a chemical compound, particularly a fatty acid, having two or more double or triple bonds in its hydrocarbon chain.

polyunsaturated

(pŏl′ē-ŭn-săch′ə-rā′tĭd)
adj.
Of or relating to long-chain carbon compounds, especially fatty acids, having two or more double bonds between the carbon atoms. Increasing dietary intake of foods containing polyunsaturated fatty acids, including safflower, sunflower, soybean, and corn oils and cold-water fish such as salmon, can decrease LDL cholesterol levels in the bloodstream.

polyunsaturated

[-unsach′ərā′tid]
Etymology: Gk, polys, many; AS, un, not; L, saturare, to fill
pertaining to a chemical compound containing more than one double or triple bond that can be opened to accept more atoms into the molecule, thereby making the compound saturated. A polyunsaturated fatty acid is one in which there are two or more double bonds in the chain of carbon atoms that can be opened to accept hydrogen atoms.

polyunsaturated

Pertaining to long chain carbon compounds, especially fatty acids, that contain more than one carbon to carbon double bonds (unsaturated bonds).
