How To Calculate The Isoelectric Point of Amino Acids and Zwitterions
Video: How To Calculate The Isoelectric Point of Amino Acids and Zwitterions

Li-amino acid ke metsoako ea manyolo e kopanang ho etsa liprotheine. Li-amino acid le liprotheine ke litšiea tsa bophelo.

Ha liprotheine li siloa kapa li robeha, li-amino acid lia sala. 'Mele oa motho o sebelisa liamino acid ho etsa liprotheine ho thusa' mele:

  • Senya lijo
  • Hola
  • Lokisa lisele tsa 'mele
  • Etsa mesebetsi e meng e mengata ea 'mele

Li-amino acid li ka sebelisoa e le mohloli oa matla ke 'mele.

Li-amino acid li arotsoe ka lihlopha tse tharo:

  • Li-amino acid tsa bohlokoa
  • Li-amino acid tse sa hlokahaleng
  • Amino acid e nang le maemo

BOHLOKOA AMINO ACIDS

  • Liamino acid tsa bohlokoa li ke ke tsa etsoa ke 'mele. Ka lebaka leo, li tlameha ho tsoa lijong.
  • Li-amino acid tse 9 ke: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan le valine.

TLHOKOMELISO AMINO ACIDS

Ho sa hlokahale ho bolela hore 'mele ea rona e hlahisa amino acid, leha re sa e fumane lijong tseo re li jang. Li-amino acid tse sa hlokahaleng li kenyelletsa: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine le tyrosine.


MAEMO AMINO ACIDS

  • Hangata li-amino acid ha li bohlokoa, ntle le nakong ea bokuli le khatello ea maikutlo.
  • Li-amino acid tse nang le maemo li kenyelletsa: arginine, cysteine, glutamine, tyrosine, glycine, ornithine, proline le serine.

Ha ho hlokahale hore u je li-amino acid tsa bohlokoa le tse sa hlokahaleng lijong tsohle, empa ho bohlokoa ho li fumana ka letsatsi lohle. Lijo tse ipapisitseng le ntho e le 'ngoe ea semela li ke ke tsa lekana, empa ha re sa tšoenyeha ka ho kopanya liprotheine (joalo ka linaoa le raese) lijong tse le' ngoe. Sebakeng seo re sheba ho lekana ha lijo ka kakaretso letsatsi lohle.

  • Li-amino acid
