types of bonding
Covalent- shared electrons between non-metal ions
Ionic -atoms gain or lose electrons to become ions with +ive or -ive charges. Opposites attract between metal and non metal atoms
Hydrogen- The shared electrons are not evenly distributed producing a polar molecule. Hydrogen bonds form between molecules
What is a monomer
A molecule that can join with another monomer to create a polymer
What is a polymer
Many monomers joined together
What is hydrolysis
The breaking of a bing by inserting a water molecule
What is condensation
Thé formation of a bond by removing a water molecule
The polymer formed by the condensation of monosaccharides
A polysaccharide
The type fo reaction that joins monomers to create polymers
Condensation
Small molecules that are joined to form polymers
Monomers
The type of reaction that breaks polymers to make monomers
Hydrolysis
Large molecule that is formed through the condensation of monomers
Polymer
Monomer formed by the hydrolysis of polypeptides
Amino acids
