CHEMISTRY GLOSSARY

DNA    →   DNK

DNA is abbreviation for deoxyribonucleic acid.

Drechsel bottle    →   Drechselova boca

See Gas washing bottle

active site    →   aktivno mjesto

Active site is a pocket or crevice on an enzyme molecule that fits reactant molecules like a hand in a glove. The active site lowers the activation energy for reaction

adenosine triphosphate    →   adenozin trifosfat

Adenosine triphosphate (ATP) is nucleotide that is of fundamental importance as a carrier of chemical energy in all living organisms. It consists of adenin linked to D-ribose).

aglycon    →   aglikon

Aglycon (aglycone) is the non-sugar compound remaining after replacement of the glycosyl group from a glycoside by a hydrogen atom. The link between the glycon and aglycon is known as glycosidic bond.

alanine    →   alanin

Alanine is hydrophobic amino acids with aliphatic side chain. It is the second simplest amino acid, but used the most in proteins. The nonpolar hydrophobic amino acids tend to cluster together within proteins, stabilizing protein structure by means of hydrophobic interactions. Alanine is a nonessential amino acid, meaning it can be manufactured by the human body, and does not need to be obtained directly through the diet.

• Abbreviations: Ala, A
• IUPAC name: 2-aminopropanoic acid
• Molecular formula: C₃H₇NO₂
• Molecular weight: 89.09 g/mol

DTA    →   DTA

DTA is abbreviation for differential thermal analysis.

electromagnetic spectrum    →   elektromagnetski spektar

See Electromagnetic radiation spectrum

fcc    →   fcc

fcc is abbreviation for face-centered cubic lattice.

formula    →   formula

See Chemical compound formula
