Polysaccharide
Polymers of carbohydrates - example = starch
Cellulose
Structural polysaccharide that makes up plant cell walls
Hydrolysis
Use water to break down polymers
Phosphate
Phosphorous bonded to four oxygens, two have negative charges, one is bonded to
the carbon skeleton
Nonpolar
Electrons shared equally
Triacylglycerol
A lipid consisting of three fatty acids linked to one glycerol molecule; also called a
fat or triglyceride
Starch
Storage polysaccharide found in plants
Fatty acid
Hydrocarbon chain with a carboxyl group at one end; majority portion in lipids
Saturated fat
Fat without double bonds, solid at room temperature
, Unsaturated fat
Fat with double bonds, liquid at room temperature
Peptide bond
Bond creating amino acid chains or polymers
Central dogma of molecular biology
Dna -> rna -> protein
Dna
Deoxyribonucleic acid
Rna
Ribonucleic acid
Monomer of nucleic acid
Nucleotide
Nucleotide composition

Functional group
Components of organic molecules most often involved in chemical reactions
Ester linkage (ester bond)
The bond between a fatty acid and a glycerol that forms a lipid
Polymer
Long molecule consisting of many similar or identical monomers linked together
Monomer
Building block for polymers; only made by producers
Hydrocarbon
