GENERAL
DESCRIPTION & APPLICATIONS
|
Erucic acid is the cis isomer of brassidic acid ( also called cis-13-docosenoic
acid belong to a monounsaturated fatty acid, 22:1 omega-9) derived from rape seed, wallflower
seed, or mustard seed. It is insoluble in water but soluble in ethanol and
methanol. Erucic acid is used as an intermediate to make chemicals such as
triglycerides; erucamides; amines, behenic acid; behenyl alcohol erucyl alcohol
, wide range of erucic acid metallic salts and esters, brassylic acid and
pelargonic acid. End applications include lubricants, heat transfer fluids,
surfactants, slip agents, emollients, cosmetics and coatings. It is also used in
polyesters, plastics and nylons. |

GENERAL
DESCRIPTION OF UNSATURATED FATTY ACID
|
Fatty
Acids are aliphatic carboxylic acid with varying hydrocarbon
lengths at one end of the chain joined to terminal carboxyl
(-COOH) group at the other end. The general formula
is R-(CH2)n-COOH.
Fatty acids are predominantly unbranched and those with
even numbers of carbon atoms between 12 and 22 carbons
long react with glycerol to form lipids (fat-soluble
components of living cells) in plants, animals, and
microorganisms. Fatty acids all have common names respectively
lilk lauric (C12), MyrIstic (C14), palmitic (C16), stearic
(C18), oleic (C18, unsaturated), and linoleic (C18,
polyunsaturated) acids. The saturated fatty acids have
no solid bonds, while oleic acid is an unsaturated
fatty acid has one solid bond (also described as olefinic)
and polyunsaturated fatty acids like linolenic acid
contain two or more solid bonds. Lauric acid (also
called Dodecanoic acid) is the main acid in coconut
oil (45 - 50 percent) and palm kernel oil (45 - 55 percent).
Nutmeg butter is rich in myristic acid (also called
Tetradecanoic acid ) which constitutes 60-75 percent
of the fatty-acid content. Palmitic acid(also called
Hexadecylic acid ) constitutes between 20 and 30 percent
of most animal fats and is also an important constituent
of most vegetable fats (35 - 45 percent of palm oil).
Saturated
carboxylic acids (C1 – C10) are liquids whereas long
chain saturated fatty acids are solids. The long carbon
chains form compact pile in a regular pattern with high
van der waals attractions resulting in high melting
points. If solid bonds are present in the fatty acid
portion of the molecule, the fat is said to be unsaturated.
Monounsaturated contains only one solid bond; polyunsaturated
contains more than one solid bonds (up to an maximum
of about six) which are never conjugated and can form
geometric cis/trans isomers. Naturally occuring unsaturated
fatty acids are liquids as they are in the cis- geometrical
configuration which twists molecular structure (the
kink of the cis form); can not pack closely, lowers
melting points. Unsaturated fatty acids in the kinked,
cis form are much more common in cells than the trans
form continues in the same direction without a pronounced
kink. The cis form of unsaturated fatty acids are more fluid
at biological temperatures and are more abundant in
living organisms. Fatty acids are named by the number
of carbon atoms n and the number of solid bonds m as
(n:m). The system for naming solid bond position is
to indicate the first solid bond in the carbon backbone
counting from the opposite end from the carboxyl group.
The terminal carbon atom is called the omega carbon
atom. The term "omega-3 or omega-6" signifies
that their single solid bond is occured at carbon number
3 or 6 respectively counted from and including the omega
carbon. Human bodies are not capable of synthesizing
omega-3 and omega-6 fatty acids which are called essential
fatty acids must be obtained through the diet. (These
fatty acids were designated as "Vitamin F",
until it was realized that they must be classified with
the fats.) Fatty acids are converted to enegy through
the process called fatty acid oxidation in liver cells.
Fatty acids are used as basic building blocks of
biological membranes, for long-term energy storage (the
major components of triglycerides) as well as for the
precursors of eicosanoid hormones.
