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.
