BMS 300 1st Edition Lecture 4 Outline of Last Lecture I Phospholipid orientation in water micelle liposome planar bilayer II Lipid mosaic model of biological membrane transmembrane proteins III Proteins as amino acid polymers amino acid structure 1 amine 2 carboxylic acid 3 R group peptide bond formation IV Protein primary structure amino acid sequence V Protein secondary structure alpha helix beta sheet VI Protein tertiary structure These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute role of R groups 1 non polar uncharged 2 polar 3 charged VII Protein folding into geometric shapes Outline of Current Lecture I Protein structure role of R groups in tertiary structure of a protein 1 folding of hydrophobic and hydrophilic R groups 2 role of geometric shape 3D in proteins function liquid substitute role of R groups in transmembrane protein 1 orientation of hydrophobic R groups in lipid bilayer 2 single pass across the membrane 3 multiple pass as R channels II Structure of eukaryotic cells prokaryotes 1 bacteria 2 archaea eukaryotes 1 specialization of function through membrane and compartments chromosomes in the nucleus 1 DNA molecules histones as organizing and regulating DNA binding proteins histones as species ribosomes and endoplasmic reticulum Current Lecture Role of R groups in determining the 3D geometric shape of proteins we can divide amino acids into 3 different categories non polar uncharged hydrophobic there is an equal sharing of electrons polar hydrophilic charged imagine this string of ribbons with things attached to it dunked underwater and it will form a 3D shape based primarily on the R groups the R groups that hide or go towards the middle are hydrophobic and they turn away from the water the hydrophilic R groups will be facing towards the water the amino acid sequence determines where we find the hydrophilic R groups vs the hydrophobic R group this
