Carbohydrates Monosaccharides

Simple Carbohydrate monosaccharides such as glucose, fructose, and galactose that cannot be broken down by water Single Replacement Reaction type of chemical reaction in which one element replaces another in a compound Smelting to melt an ore in order to refine a metal from the ore... [Pg.348]

A carbohydrate contains many V f hydroxyl groups and either an aldehyde or ketone functional group. A simple carbohydrate (monosaccharide or sugar) is an aldose if it contains an aldehyde group, or a ketose if it contains a ketone group. [Pg.1047]

Know the meaning of carbohydrate, monosaccharide, oligosaccharide, polysaccharide, disaccharide, trisaccharide. [Pg.294]

Wine is one of the most complex and interesting matrices for a number of reasons. It is composed of volatile compounds, some of them responsible for the odor, and nonvolatile compounds which cause taste sensations, such as sweetness (sugars), sourness (organic acids), bitterness (polyphenols), and saltiness (mineral substances Rapp and Mandary, 1986). With a few exceptions, those compounds need to be present in levels of 1%, or even more, to influence taste. Generally, the volatile components can be perceived in much lower concentrations, since our organs are extremely sensitive to certain aroma substances (Rapp et ah, 1986). Carbohydrates (monosaccharides, disaccharides, and polysaccharides), peptides, proteins, vitamins, and mineral substances are among the other wine constituents. [Pg.215]

The use of NCW as the mobile phase in liquid chromatography was recently reviewed. In this area, in addition to its green credentials, NCW is compatible with a range of detection methods flame ionization detection, mass spectrometry (MS) and UV (to short wavelengths). The reason for the recent growth in this area is the development of more thermally stable stationary phases. It has been used to analyse a growing number of analytes (alkylbenzenes, phenols, ketones, carboxylic acids, amino acids, carbohydrates and some pharmaceuticals). For example, carbohydrates (monosaccharides, disaccharides and sugar... [Pg.85]

Sugars are structurally the simplest carbohydrates. They are the structural unit which makes up the other types of carbohydrates. Monosaccharides are single (mono=one) sugars. Important monosaccharides include ribose (C5H10O5), glucose (C6H12O6), and fructose (same formula but different structure than glucose). [Pg.44]

Hemiacetals and hemiketals are readily formed in carbohydrates. Monosaccharides contain several hydroxyl groups and one carbonyl group. The linear form of a monosaccharide quickly undergoes an intramolecular reaction in solution to give a cyclic hemiacetal or hemiketal. [Pg.410]

Although carbon dioxide is plentiful in the natural environment it is only used in algae by photosynthesis. The usual source of carbon is via carbohydrates. Monosaccharides such as glucose are not found in nature, probably because if they are present they are rapidly utilised by cells [Lynch and Poole 1979]. Laboratory experimentation on the other hand, often uses glucose as a carbon source for the... [Pg.225]

Glucose is an example of a monosaccharide, a carbohydrate that cannot be broken down into simpler carbohydrates. Monosaccharides such as glucose rearrange in aqueous solution to form ring structures (T Figure 19.2). [Pg.697]
