Monomers • Simple organic molecules that exists individually or can link with other monomers • Examples: monosaccharide, amino acid, nucleotide
Polymers • Many monomers linked together • Example: carbohydrates, protein, nucleic acid
Carbohydrate • Monomer = monosaccharide • Elements: C, H, O • H:O=2:1
Functions • Short-term energy storage • Starch and glycogen • Structure • Chitin and cellulose • Cell-to-cell recognition
Nucleic Acids • Monomer = nucleotides • Elements: C, H, P, N O
Phosphodiester bonds form between nucleotides to form nucleic acids
Examples of Nucleic Acids • DNA (deoxyribonucleic acid) • RNA (ribonucleic acid) • ATP (adenosine triphosphate)
Proteins • Monomer = amino acids • Elements = C, H, O, N, S
Lipids • Grouped together because have 1 thing in common • No affinity for water! • Elements: C, H, O, P (sometimes)
Function • Energy storage (2x as much energy as carbs and proteins) • Structure • Cell membrane • Communication • Steroid hormones
