Macromolecules Flashcards
dehydration reaction
removes a water molecule, forming a new bond.
hydrolysis reaction
adds a water molecule, breaking a bond.
Monosaccharides
The location of the carbonyl group (aldose vs. ketose)
Disaccharide
two monosaccharides joined by glycosidic linkage.
Polysaccharides
polymers of sugars, have storage and structural roles
Why can we digest starch but not cellulose
We have enzymes that recognize starch but not cellulose
Chitin
structural polysaccharide, is found in the exoskeleton of arthropods.
Lipids
the one class of large biological molecules that do not form polymers
Triacyglycerol
made up of 3 fatty acids bound to glycerol by ester bond.
Saturated Fatty Acids
No double bonds in fatty acid chain.
Unsaturated fatty acids
one or more double bonds
Solid at room temperature?
Unsaturated fatty acids
peptide bonds
Amino acids connect to each other by forming
Primary structure
determined by the sequence of amino acids.
Secondary structure
form by hydrogen bonds between repeating amino acid units in peptide backbone.
