,Biological molecules:
WHAT ARE SOME BIOLOGICAL MOLECULES?
Carbohydrates
Fats(lipids)
Proteins
Dna
They all have carbon in common oxygen and hydrogen
WHAT IS COVALENT BONDING?
A type of bond where 2 attoms share one or more pair of electrons
WHAT IS AN IONIC BOND?
A type of bond that is formed when one ion is transferred from one attom to the other
WHAT IS HYDROGEN BONDING?
when a molecule is pulling electrons towards it so it becomes negative and the rest of the
elements lose their electrons to it it becomes positive

, WHAT IS A PLOLAR MOLECULE?
A molecule with a negative end and a positive end
WHAT IS A MONOMER? A smaller unit which larger molecules are made up of
WHAT ARE POLYMERS?
Chains of monomers formed by polymerisation
WHAT IS POLYMERISATION?
A chain of glucose can be turned to startch and chemical bonds are formed this prosses is
called polymerisation
ONE GLUCOSE MOLECULE IS CALLED MONOMER WHEN IT BECOMES A POLYMER IT
DOES NOT DISOLVE IN WATER
WHAT IS THE LATIN NAME FOR GLUCOSE: saccharides (sugar)
1 GLUCOSE IS A : saccharide
2 GLUCOSE IS A :disaccharide
2 AND MORE IS A: polysaccharide(startch)
condensation reaction
Polyneucleotides is many neucleotides so like dna

② ) H 20
sucrose
TO BREAK A BOND WE ADD WATER THIS IS CALLED HYDROLYSIS
CONSISTENT PARTS =original parts
METABOLISM: all the chemical reactions happening inside the bodies
