Properties of waxes → low melting points, stable solids, appear in both plants and animals in nature → a wax coat protects the surface of many plant leaves from water loss and attack from microorganisms What defines a carbohydrate? → aldehydes & ketones with many OH groups, or substances that form these when hydrolyzed Where do carbohydrates come from? → primary products of photosynthesis- extracts carbon from atmosphere and creates carbs out of that carbon How are monosacc...

________________ are polymers of monosaccharide monomers - polysaccharides acids - donates protons, H+ is in higher concentration aldose - carbonyl group at end of carbon chain alpha linkage - starch (more for energy storage) amino groups - attract a proton and act as bases anion - gains electrons, negative charge atomic number - number of protons, orders the elements atomic weight - mass of all the naturally occurring isotopes bases - bases - accept protons beta linkage - cellulose (m...

sucrose correct answer: glucose + fructose with a glycosidic bond simple monosaccharide correct answer: formula: (CH2O)n -simplest carbohydrates -have an aldehyde or ketone group sugars with a aldehyde have a prefix aldo- sugars with a ketone group have a prefix keto- -if a ketose, the ketone group is always at carbon 2- this decreases the amount of isomers that could form -made up of chiral carbons- allowing the sugars to form different isomers, leading to structural diversity (aldos...
