organismis ja toiduvalkudes leiduv teatud asendatav aminohape
Hea teada
Esineb kahe isomeerina, L- ja D-vormis, millest vaid L-vorm esineb looduslikult.
a hydrophilic amino acid which is a constituent of most proteins
Hea teada
Serine is 2-amino-3-hydroxypropanoic acid, CH2(OH)CH(NH2)COOH. Sometimes with modifying letter distinguishing its two optical isomers: the L-form is found in proteins and the D-form is synthesized in the brain.
Asendatavaid aminohappeid on organism alati võimeline toidus esineva defitsiidi korral ise looma. Nendeks on alaniin, aspartaanmhape, asparagiin, glutamiinhape ja seriin ..
This method makes the determination possible of free (synthetic and natural) and total (peptide bound and free) amino acids in feed, using an amino acid analyser. It is applicable to the following amino acids: cyst(e)ine, methionine, lysine, threonine, alanine, arginine, aspartic acid, glutamic acid, glycine, histidine, isoleucine, leucine, phenylalanine, proline, serine, tyrosine and valine.
