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 [...]
The following points highlight the three main reactions involved in the synthesis of fatty acids. The reactions are: 1. Initiation Reaction 2. Chain Elongation Reactions 3. Termination Reaction. 1. Initiation Reaction: In this reaction, acetyl CoA transfers its acetyl group to one of the —SH groups of multienzyme complex, i.e., fatty acid synthetase. 2. Chain Elongation Reactions: Six different reactions [...]
In this article we will discuss about:- 1. Meaning of Fatty Acids 2. Classification of Fatty Acids 3. Properties. Meaning of Fatty Acids: The acids which are combined with glycerol in the naturally occurring fats are called fatty acids. These acids contain even number of carbon atoms linked together in long chains which are in general un-branched. The chain contains [...]
