Any of a class of aliphatic carboxylic acids, of general formula CnH2n+1COOH, that occur combined with glycerol as animal or vegetable oils and fats. Only those with an even number of carbon atoms are normally found in natural fats

Note: The above general formula applies to the saturated fatty acids. Remove 2 hydrogen atoms for an unsaturated fatty acid, and 2 hydrogen atoms for every double bond in a polyunsaturated fatty acid.

In chemistry, especially biochemistry, a fatty acid is a carboxylic acid often with a long unbranched aliphatic tail (chain), which is either saturated or unsaturated. Carboxylic acids as short as butyric acid (4 carbon atoms) are considered to be fatty acids, whereas fatty acids derived from natural fats and oils may be assumed to have at least 8 carbon atoms, e.g., caprylic acid (octanoic acid)
A building block of fat
A class of compounds that contain a long chain composed of hydrogen and carbon atoms In general, fatty acids refer to any compound derived from the breakdown of fats
Any of a large group of monobasic acids, especially those found in animal and vegetable fats and oils, having the general formula CCOOH. Characteristically made up of saturated or unsaturated aliphatic compounds with an even number of carbon atoms, this group of acids includes palmitic, stearic, and oleic acids. an acid that the cells in your body need to use food effectively. Organic compound that is an important component of lipids in plants, animals, and microorganisms. Fatty acids are carboxylic acids with a long hydrocarbon chain, usually straight, as the fourth substituent group on the carboxyl (COOH) group (see functional group) that makes the molecule an acid. If the carbon-to-carbon bonds (see bonding) in that chain are all single, the fatty acid is saturated; artificial saturation is called hydrogenation. A fatty acid with one double bond is monounsaturated; one with more is polyunsaturated. These are more reactive chemically. Most unsaturated fats are liquid at room temperature, so food manufacturers hydrogenate them to make them solid (see margarine). A high level of saturated fatty acids in the diet raises blood cholesterol levels. A few fatty acids have branched chains. Others (e.g., prostaglandins) contain ring structures. Fatty acids in nature are always combined, usually with glycerol as triglycerides in fats. Oleic acid (unsaturated, with 18 carbon atoms) is almost half of human fat and is abundant in such oils as olive, palm, and peanut. Most animals, including mammals, cannot synthesize some unsaturated "essential" fatty acids; humans need linoleic, linolenic, and arachidonic acids in their diet

fatty acids
plural form of fatty acid
free fatty acid
non-esterified fatty acid
non-esterified fatty acid
Any fatty acid which occurs free, rather than esterified with glycerol to form a glyceride or other lipid; usually as the result of hydrolysis
nonesterified fatty acid
Alternative spelling of non-esterified fatty acid
omega-3 fatty acid
any polyunsaturated fatty acid having a double bond between the third and fourth carbon atoms from the end of the molecule farthest from the carboxylic acid; they are found in green vegetables and in the oils of fish such as salmon and mackerel; they are essential fatty acids, and seem to be beneficial in reducing the risk of heart disease

Both types of fish are available in cans, but unlike tuna, salmon is loaded with fat — healthy omega-3 fatty acids.

omega-6 fatty acid
any polyunsaturated fatty acid having a double bond between the sixth and seventh carbon atoms from the end of the molecule farthest from the carboxylic acid; although they are essential fatty acids, there is evidence that excess levels can cause a number of diseases

SATURATED FATS
fatty acids
organic carbon compound occurring naturally in animal and vegetable fats and oils
fatty acids
A basic unit of fats When insulin levels are too low or there is not enough glucose (sugar) to use for energy, the body burns fatty acids for energy The body then makes ketone bodies, waste products that cause the acid level in the blood to become too high This in turn may lead to ketoacidosis, a serious problem See also: Diabetic ketoacidosis

fatty acids
A natural organic compound found in animal and vegetable fats, which are made up of various combinations of fatty acids (in sets of three) connected to a glycerol molecule, making them triglycerides Each molecule a fatty acid consists of a carboxyl group (oxygen, carbon and hydrogen) attached to a chain of carbon atoms with their associated hydrogen atoms The chain of carbon atoms may be connected with single bonds of hydrogen between them, making a 'saturated' fat; or it may be connected with double bonds, making an 'unsaturated' fat The number of carbon and hydrogen atoms in the chain is what determines the qualities of that particular fatty acid For more information on how this pertains to soap-making, see The Chemistry of Soap
