The form of fatty acids (not esterized) as the leave the cell to be transported for use in another part of the body. In plasma, they immediately combine with albumin.
fatty acid hydrocarbon chains detached from other molecules, like glycerol.
Any number of saturated aliphatic monocarboxylic acids. A metabolic byproduct from the breakdown of fats. The common fatty acids of biological origin are linear chains with an even number of carbon atoms. Free fatty acids are present in living tissue at low concentrations. The esterified forms are important both as energy storage molecules and structural molecules.
The bound fatty acids in monoglycerides, diglycerides and triglycerides may be released under certain conditions, to yield free acids.
The fatty acids in a fat which are not chemically bound to glycerol molecules.
An irritating byproduct formed by the breakdown of triclycerides.
