Unsaturated fatty acids
unsaturated fatty acid
(Science: biochemistry) fatty acid with one or more double bonds.
Fatty acids have a long hydrocarbon (carbon and hydrogen) chain with a carboxyl (acid) group. The chains usually contain 16 to 18 carbons.
Fatty acids Carboxylic acids containing long hydrocarbon chains that are an important fuel source as well as a key component of membrane lipids.
Omega fatty acids
One system for naming unsaturated fatty acids is to indicate the position of the first double bond counting from the opposite end from the carboxyl group.

Chemically, fatty acids can be described as long-chain monocarboxylic acids the saturated examples of which have a general structure of CH3(CH2)nCOOH.
Fatty acids which are subunits of many lipids consist of long chains of carbon and hydrogen. The number of carbons in the chain varies but is always a multiple of two.
Fatty acids can be saturated (meaning they have as many hydrogens bonded to their carbons as possible) or unsaturated (with one or more double bonds connecting their carbons, hence fewer hydrogens).
A form of fatty acids that our body derives from food that have anti-inflammatory properties due to their ability to convert into anti-inflammatory prostaglandins.

Prostaglandins are fatty acids that behave in many ways like hormones. They are produced by most cells in the body and act on neighboring cells.
Vitamin F was the designation originally given to essential fatty acids that the body cannot manufacture. They were "de-vitaminized" because they are fatty acids. Fatty acids are a major component of fats.
We have examined the effect of dietary polyunsaturated fatty acids (PUFAs) upon mitochondrial Ca2+ content and dehydrogenase activation in the rat heart.
For example, large proteins into amino acids, or large carbohydrates into simple sugars, or large lipids into single fatty acids. And when they do that, they provide for the rest of the cell the nutrients that it needs to...
Lipids of cell membranes include phospholipids composed of glycerol, fatty acids, phosphate, and a hydrophobic organic derivative such as choline or phosphoinositol.
1995: Cardiac Single Photon Emission Computed Tomography with Iodine-123-Labeled Fatty Acids - Evaluation of Myocardial Viability with BMIPP by F.F. Knapp, Jr., P. Franken, and J. Kropp, J. of Nucl. Med. 36:1022.
They are very well known for digesting fatty acids. They also play a part in the way organisms digest alcohol (ethanol). Because they do that job, you would expect liver cells to have more peroxisomes than most other cells in a human body.
In plant cells, peroxisomes play a variety of roles including converting fatty acids to sugar and assisting chloroplasts in photorespiration. In animal cells, peroxisomes protect the cell from its own production of toxic hydrogen peroxide.
triglyceride - glycerol ester of fatty acids. The main constituent of fat droplets in animal
tissues (where fatty acids are saturated) and of vegetable oil (where fatty acids are mainly, unsaturated).
lipid A fat, oil, or fatlike compound that usually has fatty acids in its molecular structure. An organic compound consisting mainly of carbon and hydrogen atoms linked by nonpolar covalent bonds.
A long carbon chain carboxylic acid. Fatty acids vary in length and in the number and location of double bonds; three fatty acids linked to a glycerol molecule form fat.
a fat-splitting enzyme that converts fat into fatty acids and glycerin

fat (triacylglycerol)
A biological compound consisting of three fatty acids linked to one glycerol molecule.
femur
The thigh bone of tetrapods.
Autotrophs are able to build organic molecules from carbon dioxide. Heterotrophs, the "other feeders," obtain their carbon from organic compounds - amino acids, fatty acids, sugars, and so on - of autotrophs.
