Polymer: chainMonomer: link
Synthesizing & Digesting:
Two basic reactions: 1) Dehydration
synthesis– Dehydration –
water lost– Synthesis - build
• = removing a water molecule to build a polymer!!
Synthesizing & Digesting:
2) Hydrolysis– Hydro – water– Lysis – break apart
• = Using water to break apart polymers!
• DIGESTION!!!!!!!!

Primary Structure is just the specific order of amino acids in the chain.
Secondary Structures are either a helix or a pleated sheet formed form hydrogen bonds reacting between the amino acids.
Tertiary Structure occurs because of attractions between the alpha helices and pleated sheets.
Quaternary Structureis a protein consisting of more than one amino acid chain.
