Selelekela

L-Serine ke amino acid ea tlhaho, e leng karolo ea bohlokoa ea protheine synthesis ka vivo. Mokhoa oa eona oa lik'hemik'hale ke C3H7NO3 'me boima ba eona ba molek'hule ke 105.09g/mol.

 

L-Serine e na le lintho tse latelang:

1. Ponahalo: kristale e se nang mebala kapa phofo e tšoeu ea kristale;

2. Sollubility: qhibiliha ka metsing, hanyenyane feela ka joala, hoo e batlang e sa qhibilihe ka har'a metsoako ea ether le ether;

3. sebaka se qhibilihang: hoo e ka bang 228-232 ℃;

4. tatso: ka tatso e monate hanyane.

 

L-Serine e bapala karolo ea bohlokoa ho baeloji, joalo ka:

1. protheine synthesis: e le mofuta oa amino acid, L-Serine ke karolo ea bohlokoa ea protheine synthesis, e amehang khōlong ea lisele, ho lokisoa le metabolism;

2. Biocatalyst: L-Serine ke mofuta oa biocatalyst, e ka sebelisoang ho kopanya metsoako ea bioactive, e kang li-enzyme le lithethefatsi.

 

L-Serine e ka lokisoa ka mekhoa e 'meli: synthesis le ho ntšoa:

1. Mokhoa oa ho kopanya: L-Serine e ka etsoa ka karabelo ea maiketsetso. Mekhoa e tloaelehileng ea ho kopanya e kenyelletsa motsoako oa lik'hemik'hale le catalysis ea enzyme;

2. Mokhoa oa ho ntša: L-Serine e ka boela ea ntšoa linthong tsa tlhaho, tse kang libaktheria, li-fungus kapa limela ka ho belisoa.

 

Mabapi le tlhahisoleseling ea polokeho, L-Serine ke amino acid ea bohlokoa bakeng sa 'mele oa motho mme ka kakaretso e nkuoa e bolokehile. Leha ho le joalo, ho noa haholo ho ka baka litla-morao tse ling, joalo ka ho se thabise ka mpeng le ho hanana le 'mele. Ho batho ba nang le allergy e matla, ho pepesehela L-Serine ho ka baka maikutlo a ho hana. Ha u sebelisa L-Serine, ho kgothaletswa ho sebelisa ho latela keletso ea lingaka kapa litsebi, le ho laola litekanyetso ka thata.
