monomers + polymers

What is a condensation reaction

condensation reaction is a reaction that joins 2 molecules together with the formation of a chemical bond and involves the elimination of a water molecule

What is a hydrolysis reaction

hydrolysis reaction is a reaction that breaks a chemical bond between two molecules and involves the addition of a water molecule.

What are monomers + examples

the smaller, repeating units which larger molecules like polymers r made of

eg: monosaccharides, amino acids, nucleotides, glucose

What are polymers + examples

molecules made from a large number of monomers joined together in a chain

can be formed through polymerisation, where monomers are chemically bonded together.

eg: starch, cellulose, glycogen, proteins, nucleic acids (DNA + RNA)

What is a hydrogen bond

a weak electrostatic attraction that occurs between a hydrogen atom covalently bonded to an electronegative atom (eg oxygen or nitrogen) and another electronegative atom

collectively strong

What is Avogadro’s constant

6.02 X 10* 23 = avogadros constant

What is a mole

The amount of a substance (unit for how much of a substance there is)
