The following points highlight the four main groups of lipids. The groups are: 1. Triglycerides 2. Phospholipids (Membrane Lipids) 3. Steroids 4. Wax. Lipids: Group # 1. Triglycerides: One important group of stored lipids is triglycerides, a category that includes fats and oils. Triglycerides are composed of a single molecule of glycerol bound to three fatty acids (Fig. 7.1). Glycerol [...]
In this article we will discuss about fats and their distribution in plants. Introduction to Fats: Fats or glycerides or acylglycerols are esters of high molecular weight fatty acids and trihydroxy alcohol, the glycerol. Most of the glycerides in nature have all three hydroxyl groups of glycerol esterified with fatty acids and are called as triglycerides (or 'fats'). For example, [...]
Let us make an in-depth study of the glyoxylate cycle. After reading this article you will learn about 1. Steps Involved in Glyoxylate Cycle and 2. Significance of Glyoxylate Cycle. It had been observed by many plant physiologists that during the germination of fatty seeds, the fat content decreased with a simultaneous increase in sucrose (i.e., carbohydrates). This apparent conversion [...]
