BMS1041 amino acids 0.0 / 5 ? Biologybiochemistry UniversityAll boards Created by: tammyrocks4evaCreated on: 04-06-14 09:19 The isoelectric point for glycine is approx pH 6. What is the predominant charge on glycine at pH 2? positive 1 of 11 The AA with 'non-polar' aliphatic R groups are characterised by: high levels of carbon and hydrogen in the side chain 2 of 11 The AA's valine, leucine and isoleucine have the following characteristics in common? they are branched non polar aa's 3 of 11 Amongst AA's commonly found in proteins Glycine is unique as: all the things 4 of 11 The amino acids with polar uncharged R groups are characterised by: polar, uncharged groups in the side chains which can form H bonds eg OH, SH, C=O 5 of 11 Proline: Commonly found in beta turns 6 of 11 The AA with aromatic R groups are characterised by: an aromatic ring structure which gives these AA their characteristic UV spectra 7 of 11 The amino acids with 'basic R groups' are characterised by: The AA's arginine and leucine which both have positively charged side chains at neutral pH 8 of 11 The amino acids with 'acidic R groups' are characterised by? the AA's aspartate and glutamate. The negatively charged side chains can form electrostatic interactions with positively charged basic side chains. 9 of 11 The AA's hydroxyproline and hydroxylysine... are hydroxylated forms of proline and lysine, which require vit C as an enzyme cofactor for the synthesis and are found at high levels in collagen 10 of 11 Desmosine is an AA... formed of four lysine residues 11 of 11
