1.
2. It is lipophilic monohydroxybenzoic acid.
Type of phenolic acid.
Formula is C6H7O3.
Colourless crystalline organic acid.
Used in organic synthesis function as plant
hormones.
Use as key ingredients in anti-acne products.
3. White willow natural source of salicylic acid.
German researchers in 1839 isolate the herb
of meadowsweet.
Extract effective caused digestive problem ,
gastric irritation , diarrhea , even death ,
consumed in high doses.
1829 henri leroux nd italian chemist.
4. Able to convert substance into sugar nd
second component , on oxidation becomes
salicylic acid.
5. SA biosynthesis in plants have two pathways.
1 . IC pathway.iso chorismate.
2 . PAL phenylalanine ammonia-lyase pathway.
Explaination:
Isochorismate synthase an enzyme that
catalyzes irreversible reaction.
Converstion of chorismate to isochorismate.
6.
7. SA phenolic phytohormones found in plants.
Role in plant growth and development.
Photosynthesis and transpiration , ion uptake
and transport.
SA involve in endogenous signaling ,
mediating in plant defense against pathogen.
Role in resistance to pathogens by production
8. Pathogenesis related protein.
Involve in systemic acquired resistance.
Pathogen attack one part of plant induces
resistance in other part.
Signal move to nearby plant by salicylic acid
convert to the volatile ester.
SA role in plant defense against biotic nd
abiotic stresses.
9. It is used for food preservative.
Bectericidal nd antiseptic.
Use for treatment of acne.
