Intshayelelo

I-L-tyrosine yi-amino acid engabalulekanga kunye ne-polar side chain. Iiseli zingayisebenzisa ukwenza iiprotheni ezidlala indima ekutshintsheni umqondiso. I-L-tyrosine yi-proteogenic amino acid esebenza njengomamkeli we-phosphogroup edluliselwe yi-kinase.

Ngaphambili: L-2-Aminobutyric acid hydrochloride (CAS# 5959-29-5)

Okulandelayo: D-Threonine methyl ester hydrochloride (CAS# 60538-15-0)
