Proteins and Nucleic Acids
Protein types: enzymatic structural storage transport hormonal receptor contractile Building Blocks Amino acids -> Proteins Nucleotides -> DNA/RNA Shape and color are important features of building blocks Protein/Amino Acids monomer = amino acid polymer = joined by peptide bonds (dehydration reaction) Dehydration process Polymerizing amino acids ? R group dictates what the polypeptide will do Hydrophobic = CH 3 ; Hydrophilic = -OH, -SH- NH (charged particles R Groups 20 different life-building side chains (amino acids) Polypeptide polymer consisting of a large number of amino-acid residues bonded together in a chain, forming part of (or the whole of) a protein molecule
