HydrocarbonLife is made up of hydrogen and carbon stuck

together and form hydrocarbon.It is made up of 4 types of macromolecule:-proteins-nucleic acids-lipids/fats-carbohydrate

ProteinsMacromolecule

Structure Properties Function

Proteins -Amino acids stuck together by a peptide bonds-each proteins have only on shape

-Food must be digested before it become proteins-digest by breaking down the bonds in the chain

-building structure-Enzymes(controls the rate of reaction)

Nucleic acidsMacromolecule

Structure Properties Function

Nucleic acids -DNA & RNA-It is made up of pentose sugar(sugar with five carbons), nitrogenous base & phosphate group

-DNA are information

-Nucleotides = nitrogenous base+ sugar phosphate backbone

-tell a cell how to make proteins

Heredity-> passing information from parents to off-spring
