Macromolecules Benchmark SC.912.L.18.1

•Macromolecules are the BASIC STUFF OF LIFE!!

Carbohydrates-Lipids- Proteins – Nucleic Acids

They Begin as MONOMERS-

simple form and build into their

longer form POLYMERS

Carbohydrates Used for energy , or

other specific purposes depends on carb.

Structure C, H, O EXAMPLES: Monomer-

Sugar, Glucose, Fructose

Disaccharide-SucrosePolysaccharide-

Glycogen, Starch, Cellulose

Monomer -

Polymer-

Lipids Used for energy or

cell structure  or insulation,

warmthStructure varies

Proteins Used in almost all

cell function, many have very specific functions

Only one with Nitrogen

Structure: C, H, O, N and sometimes S

Monomer: Amino Acid

Polymer: PROTEIN

Nucleic Acids Used to build RNA

and DNA (our genetic code)

Nucleic Acids participate in the process of Protein Synthesis.

Monomer: Nucleotide

Polymer: Nucleic Acid – DNA
