Docosahexaenoic acid (DHA) is an omega-3 fatty acid that is a
primary structural component of the human brain, cerebral cortex,
skin, sperm, testicles and retina. It can be synthesized from
alpha-linolenic acid or obtained directly from maternal milk or
fish oil.DHA's structure is a carboxylic acid(~oic acid) with a
22-carbon chain and six cis double bonds .the first double bond is
located at the third carbon from the omega end.[3] Itstrivial name
is cervonic acid, its systematic name is
all-cis-docosa-4,7,10,13,16,19-hexa-enoic acid, and its shorthand
name is 22:6(n-3) in the nomenclature of fatty acids.
The essential n-3 fatty acid α linolenic acid (C18:3) serves as an
energy carrier and precursor for the synthesis of EPA (C20:5) and
DHA (C22:6) into which it is converted by chain elongation and
introduction of extra double bonds. EPA is an important component
of the phospholipids of cell membranes and lipoproteins. It also
serves as a precursor in the synthesis of eicosanoids, which have a
regulatory function on tissue hormones. DHA is a structural
component in the cell membranes, particularly the nervous tissue of
the brain, and plays an important role both for the synapses and
the cells of the retina.
The conversion of α-linolenic acid to its long-chain derivatives
EPA and DHA may not be sufficient to maintain optimal body
functions. The limited conversion is mainly due to a dramatic
change in eating habits during the past 150 years, resulting in
increased n-6 PUFA intake and concomitant decrease in n-3 LCPUFA
consumption in most industrialized countries. Therefore, the n-6 to
n-3 ratio in our diet has changed from 2:1 to about 10 – 20:1. This
change accounts for the inadequate biosynthesis of the biologically
active n-3 PUFA, EPA, and DHA, as n-6 and n-3 PUFA compete for the
same desaturase and elongase enzyme systems.
EPA-derived eicosanoids affect immunological processes and fulfill
anti-inflammatory functions. In addition, n-3 fatty acids have
“noneicosanoid” functions attributed to their physical properties.
They are able to modify the membrane fluidity, which is of
particular relevance in terms of erythrocytes.
1.DHA is widely used as a food supplement,it was first used
primarily in infant formulas,to promote fetal brain development.
2.DHA has the antioxidant and anti-aging function.
3.DHA can improve Blood Circulation,and lower blood pressure,it can
prevention and cure cerebral thrombosis.
4.DHA also can reducing blood fat.
