20 Amino Acids
Karten in diesem Stapel (20)
- 1Alanine Ala A- non polar
- contains one methyl group - 2Glycine Gly G- nonpolar
- 3Proline Pro P- hydrocarbon chain wraps back around and forms a covalent bond w/ the amine, thus causes restriction
- non polar
- 4Valine Val V- has a beta carbon
- has branched property (confers unique structural properties)
- non polar
- 5Leucine Leu L- non polar
- more hydrophobic surface area
- bulkier
- 6Isoleucine Ile I- branched Beta carbon
- similar to Val
- nonpolar
- 7Methionine Met M- branched Beta-carbon
- similar to Val
- nonpolar
- 8Phenylalanine Phe F- aromatic
- nonpolar
- 9Tyrosine Tyr Y- polar (-OH); participates in polar interactions and (-H) bonding
- mostly hydrophobic
- has amphipathic characteristics
- aromatic
- 10Tryptophan Trp W- absorbs light
- used for measuring protein concentration at 280 nm
- nonpolar aromatic
- 11Serine Ser S- polar, uncharged
R groups
- 12Threonine Thr T- polar, uncharged R groups
- 13Cysteine Cys C- has a thiol
- thiol readily dissociates; very reactive and bonds with other cysteines to form a disulfide bridge (covalent bond)
- polar, uncharged
- 14Asparagine Asn N- Polar, uncharged
- 15Glutamine Gln Q- Polar, uncharged
- 16Lysine Lys K- positively charged R group
- 17Arginine Arg R- Positively charged R group
- contains a guanidinium
- 18Histidine His H- serves as a proton donor and acceptor on an enzyme active site (often found on enzyme reactive sites)
- contains imidazole ring (near neutrality)
- 19Aspartate Asp D- polar, negatively charged R group
- 20Glutamate Glu E- polar, negatively charged
