comPosition And ProPerties of common oils And fAts
This table lists some of the most common naturally occurring
oils and fats . The list is separated into those of plant origin, fish
and other marine life origin, and land animal origin . The oils and
fats consist mainly of esters of glycerol (i .e ., triglycerides) with
fatty acids of 10 to 22 carbon atoms . The four fatty acids with the
highest concentration are given for each oil; concentrations are
given in weight percent . Because there is often a wide variation in
composition depending on the source of the oil sample, a range (or
sometimes an average) is generally given . More complete data on
composition, including minor fatty acids, sterols, and tocopherols,
can be found in the references .
The acids are labeled by the codes described in the previous
table, “Properties of Fatty Acids and Their Methyl Esters,” which
gives the systematic and common names of the acids . Thus 18:2
9c,12c indicates a C
18
acid with two double bonds in the 9 and 12
positions, both with a cis configuration (cis,cis-9,12-octadecadi-
enoic acid, or linoleic acid) .
The density and refractive index of the oils are typical values;
superscripts indicate the temperature in °C .
Notes:
• The composition figure given for oleic acid (18:1 9c) often
includes low levels of other 18:1 isomers .
• In some oils where a concentration is given for 18:2 9c,12c
(linoleic acid), other isomers of 18:2 may be included .
• Likewise, where a concentration is given for 18:3 9c,12c,15c
(α-linolenic acid), other isomers of 18:3 may be included .
• The acid 20:5 6c,9c,12c,15c,17c, which is prevalent in
many fish oils, is often abbreviated as 20:5 ω-3 or 20:5
n-3 .
