3. INDEX
Vitamin B 1 (thiamine)
Vitamin B 2 (riboflavin)
Vitamin B 3 (niacin )
Vitamin B 5 (pantothenic acid)
Vitamin B 6 (pyridoxine)
Vitamin B 9 (folic acid)
Vitamin B 12 ( cyanocobalamin )

4. Vitamins may be regarded as organic
compounds required in the diet in small
amounts to perfom specific biological
functions for normal maintenance of
optimum growth and health of the
organism.

5. WATER SOLUBLE VITAMIN
They are heterogeneous group of compounds - differ
chemically.
Common character – solubility in water.
Easily absorbed.
Not stored in the body except for Vit B12.
Readily excreted in urine.
Form coenzymes – biochemical reactions. Water Soluble
Vitamins

6. B-complex group of vitamins
comprise a large number of water
soluble vitamins which are
nutritional Needs for all forms of
life. that play important roles in cell
metabolism.

7. OR VITAMINE- B1
(thiamine)

8. ◦A member of the B-complex family
◦ It has a specific coenzyme, thiamine pyrophosphate
(TPP).
◦which is mostly associated with carbohydrate
metabolism.
◦Readily soluble in water.
◦Stable in acid medium.
◦Destroyed – autoclaved at 120°C for 30min.
◦Destroyed even at room temperature in an alkaline
medium.

9. Dietary sources
 Cereals, pulses, oil seeds, nut
and yeast are good sources.
 Animal foods like pork, liver,
heart, kidney, milk…..

11. Deficiency
• BeriBeri – affects principally the
cardiovascular, muscular, and
nervous system
Wet
Dry

12. WET BER - BERI
◦ Edema (accumulation of fluid in tissues
spaces) of the legs, cardiac disturbances
such as enlarged heart, systolic murmurs
and dyspnea (difficulty of breathing) may
develop
◦The pulse is rapid and irregular, and the
neck veins are distented

14. DRY BERIBERI
◦Dry beriberi is associated with
neurological manifestations resulting
in peripheral neuritis, with
progressive weakening in muscles
resulting in difficulty to walk.

16. Vitamin B 2
(riboflavin)

18. VITAMIN B 2
◦One of the B-complex vitamins .
◦Water Soluble.
◦Relatively stable.
◦Functions as coenzyme .
◦Active as flavin mononucleotide (FMN)
◦Or flavin adenine dinucleotide (FAD)

19. Dietary sources
Milk and milk products,
meat, eggs, liver, kidney
are rich sources.
 Cereals, fruits, vegetables
and fish are moderate sources.

21. Deficiency
 Gastrointestinal disease that
causes vomiting and
hypermotility of the
gastrointestinal tract

23. Angular stomatis Glossitis

25. VITAMIN B 3
One of the B-complex nutrients.
Water Soluble.
Very Stable.
Active as nicotinamide adenine dinucleotide (NAD).
And NAD-phosphate (NADP).
A peculiar vitamin since it can be synthesized in body
(via tryptophane)

26. Dietary sources
The rich natural sources of niacin
include liver, yeast, whole grains,
pulses like beans and peanuts.
Milk, fish, eggs and vegetables
are moderate sources.

28. Deficiency
Pellagra – characterized as
the disease causing 4D’s –
Dermatitis – Diarrhea –
Depression – Death

31. Pantothenic acid, also known as chick anti-
dermatitis factor or filtrate factor
Sometimes, erroneously called – Vitamin
B5
So plentiful in grains and vegetables, a
deficiency unlikely – except in complete
starvation

32. Dietary sources:
Widely distributed in plants
and animals.
 Rich sources are egg,
liver, meat, yeast, milk

34. Fatigue
Sleep disturbances
Headaches
Malaise
 Nausea
Abdominal stress
Burning, prickling sensations (paresthesia) of the hands and
feet, cramping of the leg muscles and impaired coordination

35. Fatigue Sleep disturbances

36. Headaches Malaise -अस्वस्थता

37.  Nausea जी मिचलाना Abdominal stress
पेट के तनाव

41.  Vitamin B6 also called pyridoxine is a water
soluble vitamin that is naturally present in
many foods, added to others, and available as a
dietary supplement. Your body needs it for
regular nervous system function, production of
normal red blood cells and protein metabolism.

42.  Animal sources such as egg yolk,
fish, milk, meat are rich in B6.
Wheat, corn, cabbage, roots
and tubers are good vegetable source

44. Deficiency
Early deficiency signs
– Weakness
– Irritability
– Nervousness
– Insomnia
 Later deficiency signs
– Convulsions
– Anemia
– Lesions around lips and eyes (red, crusty)

49. VITAMIN B 9
 Vitamin B9 (folic acid) is
manufactured by the human body.
Vitamin B9 is required for red blood cell
formation, energy production, formation
of amino acids, and protein metabolism.

50. Sources
• Liver
 Kidney
 Yeast
Dark green leafy vegetables
 Asparagus
 Brocoli
 Soybeans and nuts
Orange juice

53. DEFICIENCY
Anemia – often occurs in pregnant women and
also children
skin – loss of hair, grayish brown skin
pigmentation can also occur.
Nervous – mental depression & fatigue.
ORAL- severe ulcerative stomatitis may be seen.
swelling & redness of lips.

57. Vitamin b12 also called cobalamin , is a
water-soluble vitamin with a key role in
the normal functioning of the brain and
nervous system, and for the formation of
blood. It is one of the eight B vitamins.

58. Sources
Occurs primarily in animal foods, and
liver is the richest source
Meat
Eggs
Milk
 Cheese
Fish
