The following points highlight the three common types of carbohydrates in plants. The types are: 1. Monosaccharides 2. Oligosaccharides and 3. Polysaccharides. Carbohydrates Type # 1. Monosaccharides: Trioses: Six-member ring structure (Ring is in between C No. 1 and 5) D- Fructose may also exist as D-Fructopyranose i.e., six membered ring:- Carbohydrates Type # 2. Oligosaccharides: Disaccharides: (xv) Maltose (α-D-Glucopyranosyl-(1 [...]

In this article we will discuss about the breakdown and synthesis of: 1. Sucrose 2. Starch and 3. Cellulose in Plants. Breakdown of Sucrose: Sucrose is broken down or hydrolysed to yield glucose and fructose in the presence of the enzyme invertase or sucrase. The reaction is irreversible. Synthesis of Sucrose: Synthesis of sucrose in plants may take place by [...]
