Biological Molecules Section 2.3
Carbohydrates Lipids Nucleic Acids Proteins
Polymerization has many names • Polysaccharide • Glycosidic linkage • Monosaccharide + monosaccharide • Polypeptide • Peptide bond • Amino acid + amino acid • Polynucleotide • ???? bond • Nucelotide + nucleotide
Carbohydrates • Sugars (Monosaccharides) • Monomer of polysaccharide • Glucose (Blood Sugar) • Disaccharides • 2 Monosaccharide • Glycosidic Linkage • Sucrose (table sugar) (Gluc-Fruc) • Polymers of sugars (Polysaccharides) • Macromolecule • Starch, Glycogen - Energy • Cellulose, Chitin - Structure
Nulceotides Nucleic Acid • Nucleic Acid = Polynucleotide (polymer) • Nucleotide = monomer • Nucleotide consists of 3 parts • Pentose sugar • Phosphate group • Nitrogenous base
Proteins • Polymers composed of amino acids • Protein = Polypeptide (polymer) • Monomer = Amino acids • Peptide bonds • Amino acid • Amine Group (NH2) • Basic • Carboxylic Acid Group • Acidic
