biological macromolecules
lipids
monomers
glycerol
fatty acids
phosphate (in phospholipids)
constituent atoms
carbon
oxigen
hydrogen
tested by the ethanol test
positive result is white
negative result is colourless
examples
triclycerids
store energy
three fatty acids and a glycerol
phospholipids
tree fatty acids, a glycerol and a phosphate
decide what goes in and out of the cell
store energy, act as structural components for the cell membrane
proteins
monomer
Amino acids
blocks of proteins
20 diferent typs of it
constituent atoms
carbon
hydrogen
oxigen
nitrogen
polymer
polypeptides
proteins
structures of proteins
primary
sequence of a chain of amino-acids
Secondary
(alpha helix) sequence of amino-acids are linked together by hydrogen bonds
terctiary
when attractions are present between alpha helix and planted sheets
quartemary
protein consisting of more than one amino-acid chain
tested with the birruet test
negative result blue
positive result purple
carbohydrates
monosaccarides (monomer)
glucose
galactose
fructose
disaccarides
sucrose (glucose fructose)
Lactose (galactose, gluctose)
maltose (glucose, glucose)
all of them are sorces of energy :
polysaccaride (polymer)
Starch
store glucose in plants
Glycogen
store glucose in animals
cellulose
compose cell wall
constituent atoms
oxigen
hydrogen
carbon
tested with the beredicts solution
negative resylt blue
positive result brick red
Nucleic acids
monomers
nucleotides
forms nucleic acids and contain genetic information
polymers
RNA
coding, decoding, regulation, expression of genes
DNA
genetic material
ATP
energy to drive many proceses in living cells
constituent atom
carbon
hydrogen
oxigen
nitrogen
phosphate
