Chemical Components of Cells
Proteins
subunit: amino acids
Subunits linked by peptide bond
formed by condensation/dehydration
broken down by hydrolysis
Biuret Test
solution of copper sulfate and sodium hydroxide
color changed from blue to violet
Carbohydrates
polysaccharide
long chain of simple sugar
functions
storage
starch
glycogen
structure
cellulose
chitin
tests
Molish test
purple-colored solution = carbohydrate positive
Iodine test
blue black = starch positive
Benedict's test
color changes from green - orange - red brown
color depends on reducing sugar concentration
disaccharide = 2 monosaccharide
subunit: monosaccharide
Lipids
energy storage compounds
non-polar (insoluble in water)
subunit: glycerol + 3 fatty acids
tests
Emulsification
cloudy suspension
Sudan red test
red color = lipids positive
