Lysiini eli 2,6-diaminoheksaanihappo (C6H14N2O2) on yksi luonnon 20 yleisimmästä aminohaposta. Se on välttämätön aminohappo, joka tarkoittaa, että ihmiskeho ei itse pysty valmistamaan sitä muista aineista, jolloin se on saatava ravinnosta. Lysiinillä on kaksi optista isomeeria eli L-lysiini ja D-lysiini sekä raseeminen DL-lysiini. L-lysiinin CAS-numero on 56-87-1 ja D-lysiinin CAS-numero on 923-27-3 sekä DL-lysiinin CAS-numero 70-54-2.

Sen sivuketjussa on primäärinen aminoryhmä, mikä tekee lysiinistä emäksisen ja positiivisesti varautuneen fysiologisessa pH:ssa.

Biosynteesi

Biosynteesi asparagiinihaposta l-lysiiniksi.

Elintarvikkeet, joista saa lysiiniä

Suositeltava päiväannos 70 kg painavalle aikuiselle on 0,84 grammaa lysiiniä. Erityisesti kasvissyöjien on huolehdittava riittävästä lysiinin saannista.

Lysiiniä saa elintarvikkeista, joissa on korkea proteiinipitoisuus, kuten punainen liha, juustot (parmesaani), jotkut kalat, pähkinät, munat ja soijapavut.[1]

Seuraavat elintarvikkeet sisältävät merkittävän määrän lysiiniä:

  • monnikalat, joissa 9,19 % proteiinista on lysiiniä
  • kana, jossa 8,11 % proteiinista on lysiiniä
  • nauta, jossa 8,31 % proteiinista on lysiiniä
  • parmesanjuusto, jossa 7,75 % proteiinista on lysiiniä
  • maito, jossa 7,48 % proteiinista on lysiiniä. Maidon proteiinitaso on kuitenkin alhainen, vain 3,37 % maidon painosta on proteiinia.[2]
  • soijapavuissa ja linsseissä, joissa 7,42–5,74 % proteiinista on lysiiniä.
  • muna, jossa 7,27 % proteiinista on lysiiniä
  • munuainen, jossa 6,87 % proteiinista on lysiiniä.

Kliininen merkittävyys

Joissakin tutkimuksissa on osoitettu lysiinistä olevan apua herpesvirustartuntaan.

Ketogenic amino acid

Type of amino acid Summary of amino acid catabolism A ketogenic amino acid is an amino acid that can be degraded directly into acetyl-CoA, which is the precursor of ketone bodies and myelin, particularly during early childhood, when the developing brain requires high rates of myelin synthesis.[1] This is in contrast to the glucogenic amino acids, which are converted into glucose. Ketogenic amino acids are unable to be converted to glucose as both carbon atoms in the ketone body are ul...
