In this article we will discuss about the molecular structure of lipids. Lipids are another group of important biological molecules present in all cellular organisms and some viruses. Unlike the other groups of biological molecules, lipids are highly heterogenous in chemical structure. But all of them possess a common physical property which is that they are all non-polar compounds, insoluble [...]
The following points highlight the seventeen important functions of lipids. (1) Fats serve as food reserve in both plants and animals. Hibernating animals store extra fat prior to onset of winter. Migratory birds also do so before migration. (2) They function as concentrated food because as compared to carbohydrates they yield more than twice as much energy per unit weight [...]
In this article we will discuss about the Meaning and Types of Fatty Acids. Meaning of Fatty Acids: Fatty acids are organic acids having hydrocarbon chains that end in a carboxylic group (—COOH). Hydrocarbon chains may be straight or have ring structure. Some fatty acids also possess hydroxyl groups. Length is 4-24 carbons. The common fatty acids have 16 or [...]
