CARBOHYDRATES STRUCTURE: C, H, O in 1:2:1 ratio Monomer – monosaccharide Simple carbs  sugars (mono & disaccharides) Complex carbs  polysaccharides

FUNCTIONS: Energy  between C-H bonds Cell fuel – sugars (glucose) Stored E – starch, glycogen Structural Cellulose (plant cell walls) Chitin (exoskeletons) Cell Identification blood types (glycoproteins)

LIPIDS STRUCTURE: C, H, O - many more C & H Monomer – fatty acid Fatty acids connect to other molecules (like glycerol) to form triglyceride (just 1 example)

FUNCTIONS: Energy Storage More C-H bonds than carbs Cell Membranes “skin” of EVERY CELL! Steroids Chemical messengers (testosterone, estrogen)

PROTEIN STRUCTURE: C, H, O, N (sometimes Sulfer) Monomer – amino acid Amino acids link together via PEPTIDE bonds to form a polypeptide chain This chain folds up to form a functional protein

STRUCTURE (cont.): Each A.A. has different properties (polarity, charge, etc) These properties cause them to fold is specific ways 3-D shape is ESSENTIAL to proper protein function Wrong shape and protein won’t function

FUNCTIONS: Enzymes (speed up chem rxns) Structural (collagen, keratin) Chemical Messengers (insulin) Transportation (hemoglobin) Storage (caesin) Defense (anti-bodies)
