Based on given example of amino acid structure give hand written structure of all amino acids on page
"Amino Acids"[MeSH Terms]
standard 20 proteinogenic amino acids structures reference
A clean handwritten-study-notes page showing the structural formulas of all 20 standard alpha amino acids, arranged in four readable columns and five rows. Use the exact common alpha-amino-acid template for each: H2N-C(H)(R)-COOH, drawn like a simple hand-drawn cross with NH2 on the left, COOH on the right, H above the central C, and each correct side chain R below. Label each structure clearly with full name and 3-letter / 1-letter abbreviation: Glycine Gly/G (R=H); Alanine Ala/A (CH3); Valine Val/V (CH(CH3)2); Leucine Leu/L (CH2CH(CH3)2); Isoleucine Ile/I (CH(CH3)CH2CH3); Proline Pro/P (side chain -(CH2)3- closes ring to N); Methionine Met/M (CH2CH2SCH3); Phenylalanine Phe/F (CH2-benzene ring); Tryptophan Trp/W (CH2-indole); Serine Ser/S (CH2OH); Threonine Thr/T (CH(OH)CH3); Cysteine Cys/C (CH2SH); Tyrosine Tyr/Y (CH2-benzene-OH); Asparagine Asn/N (CH2CONH2); Glutamine Gln/Q (CH2CH2CONH2); Aspartic acid Asp/D (CH2COOH); Glutamic acid Glu/E (CH2CH2COOH); Lysine Lys/K (CH2CH2CH2CH2NH2); Arginine Arg/R (CH2CH2CH2NH-C(=NH)-NH2); Histidine His/H (CH2-imidazole ring). Use black ink on white ruled notebook paper, classroom handwriting, chemically correct bonds and subscripts, no surrounding screenshots or extra explanatory paragraphs.
