3. Omega 3 Fatty Acid
Omega 3 fatty acids are essential fatty acids , a class of
nutrients needed for our body to functional normally.
These are the fats of life which help our cells to
function properly. Omega 3 can’t be produced be our
body and should be supplied through the diet.

4. Types of Omega 3 acids:
1. Alpha-linolenic acid(ALA)
2. Eicosapentaenoic acid(EPA)
3. Docosahexaenoic acid(DHA)

5. ALPHA LINOLEIC ACID
Alpha-linolenic acid is an n-3 fatty acid. It is one of two essential
fatty acids, so called because they are necessary for health and can’t
be produced within the human body.

6. EICOSAPENTAENOIC ACID
EICOSAPENTAENOIC ACID is an omega-3 fatty acids. In physiologic
literature it is given the name 20:5. It also has the trivial name
timnodonic acid.

7. Docosahexaenoic Acid
Docosahexaenoic acid is an omega-3 fatty acid that is a primary
structural component of the human brain, cerebral cortex, skin,
sperm, testicles, and retina.

8. Function of omega-3 fatty Acids
Omega 3 plays a major role in a number of functions in our body. Here
are they:
• Relaxation and contraction of muscles
• Blood clotting
• Digestion
• Fertility
• Cell division
• Growth
• Movement of calcium and other substances in and out of the cells.

9. Source of omega-3
 Fish and fish oil: sardines, salmon ,tuna, trout, cod.
 Nuts and seeds: walnuts, flaxseed.
 Veggies: spinach, cauliflower, Brussels, sprouts.
 Oil: flaxseed oil, soybean oil.

10. Omega-3 Deficiency
1.rough or dry, bumpy skin
2.dry,dull brittle hair and dandruff
3.soft peeling or brittle nails
4. Excessive thirst
5. Difficulty sleeping.

11. Disease for omega3
 Attentive deficit( hyperactive)
 Alzheimer’s disease
 Schizophrenia
 Depression
 Cardiovascular disease
11

12. Treatment for Cardiovascular Disease
Omega-3 fatty acids decrease triglycerides ,lower blood pressure,
reduce blood clotting, decrease stroke and heart failure.
12

13. Neuropsychiatric Disorders
Decreased blood levels of omega-3 fatty acids have be associated
with several neuropsychiatric conditions including attention deficit
(hyperactive)disorder, Alzheimer’s disease, schizophrenia and
depression.

14. Health Benefits
 Reduce cardiovascular risk factors
 Reduces morning stiffness, swollen joints and rheumatoid
arthritis.
 Lower the risk of cancer
 Reduces inflammation throughout the body
 Reduces the risk of obesity
 Maintains fluidity of cell membrane.

15. Omega-6 fatty Acids
A class of essential fatty acids found in fish oil, especially from
salmon and other cold water fish, that acts to lower the levels of
cholesterol and LDL in the blood. LDL is the “bad" cholesterol.
15

16. Function of Omega-6 fatty Acids
 Omega-6 is essential to the body and the main omega 6 is
required by the body is linolenic acid.
 Along with omega-3, omega-6 acids also play a crucial role in
brain function, normal growth and development.
 It also helps to stimulate skin, enhance hair growth, maintain
bone health, regulate metabolism and maintain health
reproductive system.
16

17. Source of omega-6 fatty acids
• It is primarily found in vegetable oil, which are very much
abundant in all processed foods.
• Meat and dairy
• Grains and cereals
17

18. Omega-6 deficiency
 Eczema or dry ,irritated skin
 Water loss
 Hair loss
 Drying eyes
 Arthritis
 High cholesterol
 Kidney damage
18

19. Omega-6 Disease
 Non alcoholic fatty liver disease (NAFLD)
 Cardiovascular disease
 obesity
 Inflammation bowel disease (IBD)
19

20. Health benefits
 Omega-6 suppresses the immune system leaving the body more
susceptible to disease.
 Decease formation of blood clots.
 Promotes increase in cellular growth, reduce to cancer.
 It also decrease to arthritis, mood disorders, osteoporosis and
obesity.
20

21. Applications
 The fatty acids in omega-3 and omega-6 series have been integrated to
feed, food and nutraceutical products.
 Oils derived from microorganisms, called single cell oils(SCO) are
sustainable alternatives for the nutritionally important fatty acids.
 Dietary supplements are the largest segment in the application of omega-
3 PUFA but are slow growing.
 The pharmaceutical category is set to witness significant growth as a
result of consumers opting for higher concentrated omega-3 PUFA
products and purchasing omega-3 PUFA products prescribed by doctor.
