Amino Acids by side-chain

Can you name the Amino Acids through these clues?

Forced Order Answers have to be entered in order
Side-ChainAmino AcidHint
Cyclic Propyl (bonded with non-side-chain amino group) Only secondary amine of amino acids. Does not form purple complex with ninhydrin.
Methyl Simplest alpha amino acid
methyl bonded to benzylsimplest aromatic amino acid. Found in breast milk.
(1-methyl) propylNon-polar and contains two chiral carbons
propyl guanidiniumhighest acid disassociation constant of any amino acid, almost always positively charged
MethiolThiol group very nucleophillic, forms disulfide bridges
Ethyl group and Methyl group linked via sulfur(Unmodified) Proteins always start with this amino acid
1- hydroxy ethyl groupAlcohol group with two chiral centres
2- methyl indoleUsed as Flurescent probe
Side-ChainAmino AcidHint
Butyl group bonded to amino groupIn Jurassic Park, the dinosaurs were unable to produce this amino acid, ensuring they would not survive outside the park (in reality humans can't synthesise ____ either)
methyl bonded to phenolNegatively charged aromatic amino acid
hydroxy-methyl groupacts as neurotransmitter
Ethanoic Acidcoded by GAU and GAC
Methyl group bonded to carboxamideFirst amino acid isolated (from similarly named vegetable)
Propanic AcidThis acids salts grant the taste of umami
(1-methyl) ethylSmallest atomic mass of any branched chain amino acids
Ethyl group bonded to carboxamideMost abundant free amino acid in human blood
(2-methyl) propylMost common amino acid in nature
methyl imidazolePositively charged aromatic amino acid
