Proteinogenic amino acid e na le li-amino acid tse 20, tse fapaneng ka hore li ngotsoe ke liphatsa tsa lefutso, 'me li kenyelelitsoe ts'ebetsong ea ho fetolela liprotheine . Li khetholloa li thehiloe mohahong le polarity ea liketane tsa bona tse mahlakoreng.
Matlotlo a proteinogenic amino acid
Matlotlo a joalo a amino acid a itšetlehile ka sehlopha sa bona. 'Me li aroloa ke mekhahlelo e mengata, tseo u ka li thathamisang:
- ka "(" + "le" - "," pola "e sa lefelloeng, e sa lefelloeng);
- ka lihlopha tse sebetsang (sulfur tse nang le amino acid, aliphatic, monko o monate, imino acid le metsoako ea heterocyclic);
- ka mofuta oa catabolism (ketogenic amino acid, glycogen, le metsoako ea mofuta o tsoakiloeng);
- ka lik'hemik'hale (monobasic, acidic, dicarboxylic amino acids);
- ka tšimoloho (amines, tlhaho ea amino acid e fumanoang ka mokhoa o bohlale).
Sehlopha se seng le se seng se na le litšobotsi tsa sona.
Kakaretso ea proteinogenic amino acid
Ho na le lihlopha tse supileng tse joalo tsa amino acid (li ka bonoa tafoleng). Nahana ka bona:
- Aliphatic amino acid. Sehlopha sena se kenyelletsa alanine, valine, glycine, leucine le isoleucine.
- Sebabole-se nang le amino acid. Mefuta ena e kenyelletsa li-acids tse kang methionine le cysteine.
- Li-amino acid tse monko o monate. Sehlopha sena se akarelletsa phylalaine, histidine, tyrosine le tryptophan.
- Li-amino acid tse se nang lehlakore. Sehlopha sena se akarelletsa serine, threonine, asparagine, proline, glutamine.
- Imino acid. Proline, ntho e le 'ngoe feela sehlopheng sena, ho nepahetse haholo ho e bitsa amino acid ho e-na le amino acid.
- Li- acino amino acid . Li-aspartic le glutamic acid li kenyelelitsoe karolong ena.
- Li-amino acid tsa motheo. Sehlopha sena se kenyelletsa lysine, histidine le arginine.
