1. Elements and Life

2. Life N, C, O combined with Hydrogen to form ammonia, methane and water
These reacted to form micro molecules- amino acids, fatty acids, monosaccharide's, purine etc
Micro molecules gave macromolecules- proteins, polysaccharides, lipids, nucleic acids etc

3. Macro molecules → coacervates → cell membrane (enclosed with chemical compounds called protoplasm) → multi cellular plants/animals

4. Cell composition Inorganic - 81% Water - 80 Inorganic salts - 1
Organic compounds
Carbohydrates
Lipids
Proteins
Nucleotides
Others

5. Water
70% of total weight
Less for women
Amount decreases with age

6. Elements 29 elements in animal tissue Two types Essential – role known
Non-essential – role unknown

7. Essential Two types Macro – C, H, O, N, Na, K, Ca, Mg, Fe, P, S, Cl
2) Micro – Cu, Zn, Co, Mn, Mo, I, F

8. Non- essential
Br, B, Si, Ar, Ni, Al, Pb, Sn, V, Ti

9. Ca 50-70 kg body weight has 850- 1400g 99% in bones
100mg per 100mL in blood
Absorption promoted by Vit-D

10. Source milk, fish, radish, drumstick, beetroot, mustard
1L cow milk has 1200mg
1L human milk has 300mg
Sitaphal- 800mg per one fruit

11. Importance For bones Coagulation of blood
Transmission of impulse from nerve to muscle
Excitation of nerves

12. Diseases Hypocalcaemia – low Ca, affects peripheral nerves
Hypocalcaemia- high Ca, depression of nervous system

13. Na
500mg per day
To maintain osmotic pressure of body to prevent dehydration
Acts as buffer system to maintain PH in extra cellular fluids
Maintains blood viscosity

14. In medieval Europe – as headache remedy
Controls heart beat
Higher amount causes hypertension

15. S 1-3mg per day Human body has 140g
Source- egg yolk, broccoli, cauliflower, radish, onion, garlic

16. Importance
Boosting resistance to disease Regulate blood sugar Prevent aches and pains For forming hair, skin, nails, nose cartilage, pads the joints antibacterial

17. Diseases Skin disorder Muscle pain Nerve disorder, arthritis
Inflammation
constipation

18. Iodine Adult body has 20- 30mg Important for thyroid hormone
Source – food, water, salt, sea fish, cod liver oil
in common salt 1: 10000
Deficiency - goiter

19. Fe 3- 4 g in body 75% in blood Vit C favours absorption
Absorbed as Ferrous

20. Function
Oxygen transfer, in enzymes, for metabolic oxidation

21. Source
Liver, poultry, beef, fish, egg, carrot, apple, banana, orange, cheese, tomato, spinach
Disease- Anemia

22. Conclusion
Beware and be aware of chemical for a better life
