Amino acids Flashcards
Draw the structure of Glycine
Alpha carbon with amino group, carboxylic acid group, and TWO hydrogens.
Draw the structure of Alanine
Alpha carbon with amino group, carboxylic acid group, hydrogen and a methyl R group.
Draw the structure of Valine
Alpha carbon with amino group, carboxylic acid group, hydrogen and isopropyl R group.
Draw the structure of Leucine
Alpha carbon with amino group, carboxylic acid group, hydrogen and isobutyl R group.
Draw the structure of Isoleucine
Alpha carbon with amino group, carboxylic acid group, hydrogen and sec-butyl R group.
Draw the structure of Methionine
Alpha carbon with amino group, carboxylic acid group, hydrogen and CH2-CH2-S-CH3 R group.
Draw the structure of Proline
Alpha carbon with carboxylic acid group, hydrogen and a 3 carbon chain forming a five-membered ring with nitrogen (NH2+ attached to alpha carbon and the third carbon in “R-group”)
Draw the structure of Phenylalanine
Alpha carbon with amino group, carboxylic acid group, hydrogen and a benzyl (CH2-phenyl) R group.
Draw the structure of Tryptophan
Alpha carbon with amino group, carboxylic acid group, hydrogen and an indole ring joined to a methylene (-CH2-) group. It is joined to the indole ring at the first carbon of the five-membered ring.
Draw the structure of Serine
Alpha carbon with amino group, carboxylic acid group, hydrogen and CH2-OH R group.
Draw the structure of Threonine
Alpha carbon with amino group, carboxylic acid group, hydrogen and CH(CH3)OH R group.
Draw the sturcture of Tyrosine
Alpha carbon with amino group, carboxylic acid group, hydrogen and -CH2- attached to p-Toluene R group.
Draw the structure of Cysteine
Alpha carbon with amino group, carboxylic acid group, hydrogen and -CH2-SH R group.
Draw the structure of Asparagine
Alpha carbon with amino group, carboxylic acid group, hydrogen and CH2-(C=O)-NH2 (-CH2- carboxamide)
Draw the structure of Glutamine
Alpha carbon with amino group, carboxylic acid group, hydrogen and -CH2CH2-(C=O)-NH2 (-CH2CH2- carboxamide)
Draw the structure of Lysine
Alpha carbon with amino group, carboxylic acid group, hydrogen and -(CH2)4-NH3+ R group.
Draw the structure of Arginine
Alpha carbon with amino group, carboxylic acid group, hydrogen and -(CH2)3-NH-C(NH2)2+ (3 carbons topped by Guanidinium group). It is attached to the guanidinium group by one of the Nitrogens (one of the hydrogens is substituted).
Draw the structure of Histidine
Alpha carbon with amino group, carboxylic acid group, hydrogen and -CH2-Imidazole. It is joined to the imidazole ring at the carbon adjacent to sp2 nitrogen that is not also adjacent to sp3 nitrogen.
Draw the structure of Aspartate
Alpha carbon with amino group, carboxylic acid group, hydrogen and -CH2-COO (deprotonated carboxylic acid)
Draw the structure of Glutamate
Alpha carbon with amino group, carboxylic acid group, hydrogen and -CH2-CH2-COO (deprotonated carboxylic acid group)
Draw an Indole ring
Benzene with C=C-NH tethered between two double-bonded carbons.
Draw an Imidazole ring
Five-membered ring containing one Sp3 nitrogen and one Sp2 nitrogen separated by an Sp2 carbon. Other atoms are Sp2 carbons.
Draw the Guanidinium group
Carbon with three NH2 groups.
