In this article we will discuss about soaps and synthetic detergents. Soaps: Soaps are salts of long chain fatty acids. Alkaline hydrolysis of a fat or oil produces a soap and glycerol. The older method of soap production consisted of treating molten tallow (the fat of livestock) with a slight excess of alkali in large open kettles. The mixture was [...]
In this article we will discuss about:- 1. Meaning of Fatty Acids 2. Roles of Fatty Acids 3. Nomenclature. Meaning of Fatty Acids: Since fats and oils both contain glycerol, the differences between them must be due to differences in their fatty acid components. It is therefore customary to describe triacylglycerols in terms of their fatty acids. Fatty acids are [...]
The below mentioned article provides notes on Urea Cycle. Whenever amino acids are utilised for energy production or for the synthesis of glycogen or fat, an amino group is liberated in the form of ammonia. Living organisms must have some mechanisms of removing this ammonia from the cell environment because even low concentrations of ammonia are poisonous. (Levels of only [...]
