Corn, peanut, cottonseed, soy bean, and many plant oils
Linoleic
Frequently found with linoleic acid but particularly in linseed oil
a-linolenic
Some plants, eg., oil of evening primrose, borage oil; minor fatty acid in animals
y-linolenic
Found in animal fats; important component of phospholipids in animals
arachidonic
Fish, oils,algal oils, phospholipids in brain
Cervonic
Important components of fish oils, eg., cod liver, mackerel, menhaden, salmon oils
Timnodonic
Cyclopentane ring is interrupted with an oxygen atom (oxane ring)
THROMBOXANES
Conjugated double bonds in a molecule means that the single and double bonds alternate.
Leukotrienes
single and double bonds alternate.
Conjugate bonds
can be synthesized in the body
Non-essential fatty acids
that must be provided by foods because they cannot be synthesized in the body
Polyunsaturated fatty acids (PUFA)
can only be derived from dietary sources as the enzymes needed to synthesize these two EFAs are lacking in the human body
LA and ALA
LA
linoleic acid
ALA –
alpha-linolenic acid
alcohol + fatty acid + phosphoric acid residue
Phospholipids
alcohol is GLYCEROL
Glycerophospholipids
alcohol is SPHINGOSINE
Sphingophospholipids:
Phospholipids may be regarded as derivatives of
phosphatidic acid
Phospholipids may be regarded as derivatives of phosphatidic acid, in which the phosphate is esterified with the —
—OH of a suitable alcohol.
is important as an intermediate in the synthesis of triacylglycerols as well as phosphoglycerols
Phosphatidic acid
