Category Archives for "Lipids"

The lipids are the important constituents of the diet because of their high energy value and also because of the fat-soluble vitamins and the essential fatty acids. This category includes structure, classification and functions of Lipids.

Fatty acids are the Building Blocks of Fats and Oils (Short Notes)

Do you know fatty acids are the basic unit of which macromolecules? Fats are esters of high molecular weight containing Fatty acids(FA) and Glycerol. Glycerol is a trihydric alcohol and therefore one two or all the three hydroxyl groups (OH) can react with FA forming mono, di or triglycerides respectively. These are the basic questions. To solve […]

Essential Fatty Acids Definition and Notes in Biology

The mammalian body is able to synthesize fatty acids from the Oleic acid. However, this is not the case with some fatty acids to 34 carbon atoms containing two or more double bonds; they are produced only by bacteria or plants. Mammals cannot therefore get their food. They are called essential fatty acids. They are also sometimes called vitamin F (outdated name). The linoleic acid and linolenic acid are essential […]

What are Lipids ? What are the Importance in Human Body

Lipids are involved mainly with long-term energy storage. They are generally insoluble in polar substances such as water. Secondary functions of lipids include structural components (as in the case of phospholipids that are the major building block in cell membranes) and “messengers” (hormones) that play roles in communications within and between cells. Lipids Definition: Lipids […]

Qualitative Analysis : Color Reactions of Lipids

Lipids are one of the major constituents of foods, and are important in our diet for a number of reasons. They are a major source of energy and provide essential lipid nutrients. Nevertheless, over-consumption of certain lipid components can be detrimental to our health, e.g. cholesterol and saturated fats. In many foods the lipid component […]
