What word should you always associate with lipids? The term “lipid” refers to a wide range of compounds that are hydrophobic but insoluble in water. These molecules are hydrocarbons with a carbon-carbon double bonds, but less oxygen than carbohydrate. They are essential components of the body’s plasma membrane, serving as a storage facility for energy and fuel.
Both fats and lipids are solids at room temperatures. They are present in plants and animals and contain varying proportions of saturated and unsaturated fatty acids. Carotene, 3-hydroxy-2-butanone and carotene are responsible for the color and odor of butter. Both of these compounds are produced by the bacteria that ripen cream.
There are many compounds called lipids that can be found in the body. They are soluble in organic solvents but insoluble in water. Because they contain fatty acid, fats and oils are considered lipids. Fats, which are esters of the trihydroxy alcohol glycerol, are considered lipids. Among them are fatty acids, amino alcohols, steroids, and waxes.
Lipoproteins are composed of both hydrophilic and hydrophobic parts. Their hydrophobic tails act as a barrier between the outer and inner surfaces. This barrier allows them to form a monolayer on the water’s surface. The hydrophobic part is sandwiched between the two surfaces, while the hydrophilic heads are on the outer surface. Once they have reached the water surface, they disperse into micelles, monolayers, and bilayers.
