Glycine

Glycine(faapuupuu Gly), e lauiloa foi o le acetic acid, o se amino acid e le taua, o lona fualaʻau vailaʻau o le C2H5NO2.Glycine o se amino acid o le endogenous antioxidant faʻaitiitia glutathione, lea e masani ona faʻaopoopoina e puna mai fafo pe a oʻo i le tino i lalo o le faʻalavelave ogaoga. , ma o nisi taimi e taʻua o le amino acid semi-essential. Glycine o se tasi o amino acids sili ona faigofie.

Glycine1mea tau vaila'au:

Paʻepaʻe monoclinic poʻo tioata hexagonal, poʻo paʻepaʻe tioata paʻepaʻe.Le manogi, ma le tofo suamalie faapitoa.Faigofie i le vai, solubility i le vai: 25g/100ml i le 25℃;I le 50 ℃, 39.1g/10Chemicalbook0ml;54.4g/100ml ile 75℃;I le 100 ℃, e 67.2g/100ml.E matua le mafai ona solu i le ethanol, e tusa ma le 0.06g fa'amavae i le 100g anhydrous ethanol.Toeititi lava le mafai ona solu i le acetone ma le eter.

Gaosiga auala:

Strecker auala ma le chloro-acetic acid ammonification metotia o auala autu ia sauniuni.

auala Strecker:formaldehyde, sodium cyanide, ammonium chloride tali faʻatasi, ona faʻaopopo lea o le glacial acetic acid, precipitation o le methylene aminoacetonitrile;Amino acetonitrile sulfate na maua e ala i le faaopoopoina o le methylene acetonitrile i le ethanol i le i ai o le sulfuric acid.O le sulfate e pala e le barium hydroxide e maua ai le glycine barium masima;Ona faaopoopo lea o le sulfuric acid e faʻafefe ai le barium, faʻamama, faʻapipiʻi le filtrate, ma a maeʻa ona faʻamafanafana e faʻafefe ai tioata glycine.O se su'ega [NaCN] – > [NH4Cl] CH2 = N – CH2CNCH2 = N – CH2CN [- H2SO4] – > [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, – H2SO4 [BChemicalbooka (OH) 2] – (NH2CH2COO) 2COO ba (NH2CHO) 2 ba [- H2SO4] – > H2NCH2COOH

Chloro-acetic acid ammoniation auala:vai ammonia ma le ammonium bicarbonate faʻafefiloi faʻamafanafana i le 55 ℃, faʻaopoopo le chloro-acetic acid vai vaifofo, tali mo le 2h, ona faʻamafanafanaina lea i le 80 ℃ e aveese ai le ammonia totoe, decolorization ma activated carbon, filtration.O le vaifofo fa'a'ese'ese na fa'aopoopoina i le 95% ethanol e fa'ameamea ai le glycine, fa'amama, fufulu i le ethanol ma fa'amago ina ia maua ai le oloa mama.Fa'amuta ile vai vevela ma toe fa'ama'i ile ethanol e maua ai le glycine.H2NCH2COOH ClCH2COOH [NH4HCO3] – > [NH4OH]

E le gata i lea, o le glycine e maua mai foi mai le siliki hydrolyzate ma faʻafefeteina i le gelatin e fai ma mea mata.
