BMS1041 amino acids

HideShow resource information
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
