SUBJECT: CHEMISTRY
CHEMISTRY IN EVERYDAY LIFE
POINTS TO BE REMEMBERED
1. DRUGS–Drugs are chemical of low molecular masses, which interact with
macromolecular targets and produce a biological response.
2. CHEMOTHERAPY- The use of chemicals for therapeutic effect is called chemotherapy.
3. CLASSIFICATION OF DRUGS –
(a) ON THE BASIS OF PHARMACOLOGICAL EFFECT- drugs for a particular type of
problem as analgesics for pain relieving.
(b) ON THE BASIS OF DRUG ACTION-Action of drug on a particular biochemical
process. for example all anti histamines inhibit the action of histamines which causes
inflammations in the body.
(c) ON THE BASIS OF CHEMICAL ACTION-Drugs having similar structure. Eg.-
sulpha drugs.
(d) ON THE BASIS OF MOLECULAR TARGETS-Drugs interacting with biomolecules
aslipids, proteins.
4. ENZYMES AS DRUG TARGETS
i) CATALYTIC ACTION OF ENZYMES-
(a) Enzymes have active sites which hold the substrate molecule .it can be
attracted by reacting molecules.
(b) Substrate is bonded to active sites through hydrogen bonds, ionic bonds,
VanderWaal or dipole –dipole interactions.
(ii) DRUG- ENZYME INTERACTIONS-
(a) Drug compete with natural substrate for their attachments on the active sites
of enzymes. They are called competitive inhibitors.
(b) Some drugs binds to a different site of the enzyme called allosteric sites which
changes the shape of active sites.
5. ANTAGONISTS- The drugs that bind to the receptor site and inhibit its natural
function.
6. AGONISTS- Drugs mimic the natural messenger by switching on the receptor.
7. ANTACIDS-These are compounds which neutralize excess acid of stomach.
eg- Aluminium hydroxide, Magnesium hydroxide.
8. ANTI HISTAMINES-The drugs which interfere with the natural action of histamines and
prevent the allergic reaction. eg- ranitidine, Tegamet(cimetidine), terfenadine, avil,
bromophenaramine.
9. TRANQULIZERS-The class of chemical compounds used for the treatment of stress, mild
or even severe mental diseases. eg-,nor adrenaline iproniazid, luminal, seconal, equanil .
10. ANALGESICS-They reduce pain without causing impairment of consciousness, mental
confusion or some other disturbance of the nervous system. Eg- aspirin, saridon , phenacetin.
11. ANTIMICROBIALS-They tend to prevent/destroy or inhibit the pathogenic action
of microbes as bacteria ,virus ,fungi etc .They are classified as
i) Bactericidal eg:-Pencillin,Ofloxacin
ii) Bacteriostatic eg:-Erythromycin,Tetracycline
ANTIBIOTICS- Those are the chemicals substances which are produced by micro-
organisms. eg- Pencillin , ofloxacin .They inhibit the growth or destroy micro organism
by intervening in their metabolism.
NARROW SPECTRUM ANTI-BIOTICS-These are effective mainly against gram
positive or gram negative bacteria. eg- Penicillin , streptomycin.
BROAD SPECTRUM ANTI-BIOTICS-They kill or inhibit a wide range of micro-
organisms. eg- chloramphenicol , tetracycline .
ANTISEPTIC DISINFECTANTS
These are the one which either kill/ inhibit the growth of micro- organisms
Antiseptics are applied to the living tissues such as wounds, cuts, ulcers etc. eg- furacine,
chloroxylenol&terpineol (dettol). Disinfectant are applied to inanimate objects such as
floors, drainage, system.
Eg-0.2% solution of phenol is an antiseptic while 1%solution is a disinfectant.

help in their preservation for longer period.eg, Butylated hydroxytoluene(BHT), BHA
15. CLEANSING AGENTS-
(i) SOAPS-They are sodium or potassium salts of long chain fatty acids. They are
obtained by the saponification reaction, when fatty acids are heated with aqueous sodium
hydroxide. They do not work well in hard water.
(ii) TOILETS SOAP-That are prepared by using better grade of fatty acids and excess of
alkali needs to be removed .colour & perfumes are added to make them attractive.
(iii) MEDICATED SOAPS-Substances of medicinal value are added.eg- Biothional
,dettol.

actually contain no soap .They can be used in both soft and hard water .They are-
(i)ANIONIC DETERGENTS-They are sodium salts of sulphonated long chain alcohols
or hydrocarbons.eg-sodium lauryl sulphonate . They are effective in acidic solution.The
anionic part of molecule is involved in the cleansing action.
(ii)CATIONIC DETERGENTS- They are quarternary ammonium salts of amines with
acetates, chlorides, or bromides. They are expensive used to limited extent.eg-
cetyltrimethyl ammonium bromide . The Cationic part of molecule is responsible for
cleansing action.
(iii)NON-IONICDETERGENTS-They do not contain any ions. Some liquid dish washing
detergents which are of non-ionic type
eg:-Polyethyleneglycol stearate.
17. BIODEGREDABLE DETERGENTS-The detergents which are linear and can be
attacked by micro- organisms are biodegradable.
