CHEMISTRY GLOSSARY

threonine    →   treonin

Threonine is neutral amino acids with polar side chains. It differs from serine by having a methyl substituent in place of one of the hydrogens on the β carbon. Threonine is a site of phosphorylation and glycosylation which is important for enzyme regulation and cell signaling. It is an essential amino acid, which means that humans cannot synthesize it, so it must be ingested.

• Abbreviations: Thr, T
• IUPAC name: 2-amino-3-hydroxybutanoic acid
• Molecular formula: C₄H₉NO₃
• Molecular weight: 119.12 g/mol

triclinic crystal system    →   triklinski kristalni sustav

Minerals of the triclinic crystal system are referred to three unequal axes, all of which intersect at oblique angles. None of the axes are perpendicular to any other axis.

triclinic lattice    →   triklinska rešetka

Triclinic lattice has one lattice point at the each corner of the unit cell. It has unit cell vectors a≠b≠c and interaxial angles α≠β≠γ≠90°.
