Equine Nutrition AGR 479/564. Introduction. Why are fats or oils used in equine diets?. To increase in energy density. Substitute energy for CHO’s. However, even more so. Improved energetic efficiency. Equine Nutrition AGR 479/564. Introduction. Why are fats or oils used in equine diets?. To increase in energy density. Substitute energy for CHO’s. However, even more so. Improved energetic efficiency. Lipids are relatively insoluble in water.. They are soluble in . nonpolar. solvents such as chloroform , diethyl ether, acetone, benzene and ether.. The hydrophobic (water hating) nature of lipids is due to the predominance of hydrocarbon chain.(-CH2-CH2-CH2-) in their structure. Carboxylic Acid Derivatives. Chapter 14. 1. Carboxylic acids.

Karboxylsyrer. Structure. Carboxylic acid groups consist of two very polar functional groups. Carbonyl group. Hydroxyl group. Carboxylic acid groups are very polar. Similarly, irregularly shaped chips would be like unsaturated fatty acids that do not fit closely together.. Learning . Goal .

LIPIDS Lipids are heterogeneous group of molecules related to fatty acids . They are hydrophobic and are characterized by sparing solubility inwater but high solubility in non - polar solvents su Prof. Mamoun Ahram. Resources. This lecture. Lippincott’s Biochemistry, Ch. 15. What are lipids?. Lipids are heterogeneous, hydrophobic, compartmentalized in membranes, as droplets of triacylglycerol (TAG), or in lipoprotein (LP) particles or, or protein-bound. .
