Lipids include fats‚ and the main function of fat is energy storage in animals. Fats are even richer in energy than

investigated. Methanolic and aqueous extract of leaves and fruits of P. niruri showed inhibition of membrane lipid peroxidation (LPO)‚ scavenging of 1‚1-diphenyl-2picrylhydrazyl (DPPH) radical and inhibition of reactive oxygen species (ROS) in vitro. Antioxidant activity of the extracts were also demonstrable in vivo by the inhibition of the carbon tetrachloride (CCl4) – induced formation of lipid peroxides in the liver of rats by pretreatment with the extracts. CCl4 – induced hepatotoxicity in rats

The Role of Lipids in the Body Donna Pote Western Governors University The Role of Lipids in the Body We have all been told at one time or another to be careful to limit the amount of fat in our diets. The thing is‚ fats play an important role in our body. They store and provide energy‚ insulate and protect our organs‚ and act as messengers‚ helping protein do their jobs. They start chemical reactions that help our immune system‚ reproduction and other aspects of basic metabolism. (Dutchen‚ 2010)

Explain the importance of a positive and a negative control in biochemical test. Use biochemical test to identify an unknown compound. Background Most organic compounds in living organisms are carbohydrates‚ proteins‚ lipids‚ and nucleic acids they are called macromolecules

Lipids & Fat Casey G. Turner‚ RN Western Governors University Lipids & ATP • Fatty acids are important to energy production. They generate ATP. • This is completed by: 1. Starting with a triglyceride molecule the fatty acid part separates from the glycerol part of the molecule. 2. Once separated‚ the fatty acid chain will break into sections. Each section will be composed of 2 carbon molecules. 3. Each of the carbon pieces will form Acetyl CoA. Each Acetyl CoA enters the Krebs Cycle. 4. It is

enough. EMULSION TEST FOR lIPIDS The lipids are a large and diverse group of naturally occurring organic compounds that are related by their solubility in nonpolar organic solvents The emulsion test is a method to determine the presence of lipids using wet chemistry. The procedure is for the sample to be suspended in ethanol‚ allowing lipids present to dissolve (lipids are soluble in alcohols). The liquid (alcohol with dissolved fat) is then decanted into water. Since lipids do not dissolve in water
