Concept explainers
(a)
Interpretation:
The structure of glyceraldehyde is to be shown.
Concept introduction:
Monosaccharides are the simplest form of sugars. The monosaccharide cannot be hydrolysed into simpler units. Examples of monosaccharides are glucose and fructose. When monosaccharides are joined by glycosidic linkages, higher sugars are obtained.
(b)
Interpretation:
The reason for a
