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!!!!!!!!

Enzymes

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.
