Two imp charecters of nitrogenase complex are 
ATP seems to play a catalytic role rather than thermodynamic
another imp property is extremly labile when o2 is present.

The molecular weight of cellulose is between 200,000  and 
2,000,000.It is formed by taking out a molecule of water 
from the glycosidic  oh group  on carbon atom 1 of one 
beta -d- glucose molecule  and alcoholic  OH  group on 
carbon atom  of the adjasceent  beta-d- glucose molecule.it 
resambles in its structure with amylose except that the 
glucose units are linked together by beta-1,4-glucoside 
linkages.Cellulose is actually an anhydride of beta-d- 
glucose units.

Glucose ,fructose,mannose are interconvertible in weak
alkhaline solutions such as ca(oh)2 and ba(oh)2 at low
temperatures.this reaction is known as lobry debruyn-alberda
van ekenstein transformation.mechanism involves miogration of
proton from carbon atom onto oxygen of an adjascent carbonyl
group resulting in formation of unsaturated alcohol called
enol..33

CM cellulose and DEAE cellulose

Chlesterol has a molecular formula of c27h46o.its structure
is 3-hydroxy-5,6-cholestane.

MUFA-containing olive oil consumption was associated with 
higher plasma total cholesterol, LDL-C, and triglyceride 
concentrations when compared to PUFA-containing corn oil 
consumption.
PUFA, but not MUFA, rich oils decrease HDL cholesterol 
concentratiophytosterols, perhaps working through 
inhibition of cholesterol absorption, are at least in part 
responsible for the differential effects on cholesterol 
synthesis observed between MUFA- and PUFA-containing oils.
Epidemiological studies have demonstrated that plasma 
triglyceride concentrations correlate positively with MUFA 
and negatively with PUFA intakes.

MUFA is known as good cholesterol as it has high HDL which 
helps in maintaining the cholestrerol level...PUFA is know 
as bad cholesterol as it has high LDL which increases the 
amount of cholesterol in d body.High HDL helps in digestion 
of fats.

BIOTIN is synonymous to the antiegg injury factor
responsible for the cure of egg white injury induced in rats
 and other animals by feeding them with raw egg white.

Phtyin obtained from cereal group established as vitamin 'b"
group called as mouse antilopecia faCTOR.FOUND IN MUSCLES
CALLED AS MUSCLE SUGAR .OCCURS IN 4 FORMS NAMELY FREE
INOSITOL,PHYTIN,PHOSPHATIDYLINOSITOL,NONDIALYZBLE
COMPLERX.chemical structure is C6H12O6 OR C6H6(OH)6.

The test is called folin's test. blue colour developes with
phosphomolybdotungstic acid in alkhaline solution due to the
presence of phenol group.Tthis test is specific test for
tyrosine.

Heteropoly saccharides are produced by the hydrolysis of 
different polysacharides .thir general formula is (C6H10O5)X.
EXAMPLES ARE SPECIFIC SOLUBLE SUGAR OF PNEUMOCOCCUS
TYPE111,HYALURONIC ACID,CHONDRIOTIN.

Most of the triglycerides are of mixednature.They contain 2
or 3 different fattyacid units in molecule.the two
triglycerides are oleodipalmitin and oleopalmitostearin.

The atomic weights are in fractions because of the presence 
of isotopes for a particular compound.

The name vitamin b6 suggested to designate substances other than
thiamine and riboflavine which cured adermatitis
inrats. It was named as aderminor antidermatitis
factor. This include spyridoxin, pyridoxal, pyridoxamine having
molecular formula of c5h5n.

Two hormones are secreted from echinodermata. they are
gonad stimulising hormone with molecular weight of 2000
synthesised in radial nerves.
maturation inducing substance  produced by ovarian follicles.
