Carbohydrate Analysis
245
HPAEC-PAD
High-performance anion-exchange chromatography with pulsed amperometric
detection; an HPLC system developed for polyalcohols.
HPLC
High-performance liquid chromatography; a method for separating molecules in
solution, often conducted at relatively high pressures.
ICUMSA
The International Commission for Uniform Methods of Sugar Analysis, c/o British
Sugar plc, Technical Centre, Colney, Norwich, UK. Publishes standardized methods of
food carbohydrate analysis at regular intervals.
Lectins
Proteins or glycoproteins of nonimmune origin that bind carbohydrates.
MALDI-TOF
Matrix-assisted laser-desorption ionization mass spectrometry.
MALLS
Multiangle laser light scattering is a technique for determining the molecular weight of
polymers.
NMR
Nuclear magnetic resonance; a spectroscopic process for examining nuclear
environments.
NOESY
Nuclear Overhauser effect spectroscopy. A two-dimensional NMR technique that
determines the through-space relationship of atoms.
O-Glycoside
Compounds in which a sugar is linked to another molecule through its reducing group
to form an acetal.
ROESY
Rotational nuclear Overhauser effect spectroscopy. A variation in the two-dimensional
NMR NOESY technique that determines the through-space relationship of atoms. It is
especially useful for cases in which NOESY signals are weak in spite of atoms being
close.
SEC
Size-exclusion chromatography is a technique that separates on the basis of molecular
size.
