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 following points highlight the five main forces that stabilise protein structures. The forces are: 1. Salt Linkages 2. Hydrogen Bonding 3. Disulfide Linkages 4. Hydrophobic Interactions 5. Van der Waals' Forces. Force # 1. Salt Linkages: Salt linkages (ionic bonds) result from interactions between positively and negatively charged groups on the side chains of the basic and acidic amino [...]
