chemical composition of cells :check:
carbohydrate :
monosaccharide
(glucose)
(fructose)
(galactose)
disaccharide
(sucrose)
(lactose)
(maltose)
polysaccharide
storage polysaccharides
(glycogen)
(starch)
iodine test used to test the presence of starch by changing the color for black.
structural polysaccharide
cellulose
chitin
Molish test
used to test the presence of carbohydrate
changing the color of solution to purple-red.
Protein
is an amino-acids that connected with each other by peptide bond that form by dehydration reaction.
biuret test
to test the presence of peptide bond
changing the color of solution from blue to violet
lipids
the energy storage.
consist of nonpolar molecules
need emulsifier to dissolve in water
Sudan test
if the result is red homogenous solution it is positive for lipids.
is used to test the presence of lipids
reducing sugars
all monosaccharides and some disaccharides that have a free reactive carbonyl group are reducing sugars. sucrose for example, is a non -reducing sugar
The color of the solution will change depends on the amount of precipitate that formed. darker color means more reducing sugar presence in the solution.
protein functions:
blood
enzymes
supporting strength of hair , nails
muscels
brain ,nerves
cellular massenger
antibodies
