Organic MACROMOLECULES Large & complex CHONPS atoms • CELLULOSE polypeptide polysaccharide
carbohydrates nucleic acids proteins See any patterns? lipids
Macromolecules are made by linking together repeated small molecules each link = monomer chain = polymer Each link is a monomer The chain is a polymer Gr: mono- one poly- many
Ex: chains of simple sugars, like glucose, create complex carbohydrates, like starch monomer = glucose polymer = starch
CHEMICAL DIGESTION Polymer -> monomers • make small enough to diffuse from gut to bloodstream • make raw materials available for assembly into new molecules • aided by enzymes (-ase), gut microbiota
Water breaks the bonds of a polymer HYDROLYSIS polymer add water dimer octet rule satisfied add water http://nhscience.lonestar.edu/biol/dehydrat/dehydrat.html
Building polymers is a DEHYDRATION SYNTHESIS reaction water covalent bonding creating a disaccaride water peptide bonding of amino acids
