Nutrients are the chemicals that humans need to live and grow. Humans obtain their nutrients from the food and water that they drink. They are used to build and repair tissues and regulate body processes and are converted to and used as energy. Lipids are a category of nutrients. Lipids consist of fats, oils, and waxes and are very important for are body’s health. Lipids are important for the human body because they are for storing energy, they’re good at storing energy because they can concentrate a group of calories in a smaller area.
There are many functions lipids have. One of the main functions lipids are structural components in the cell. Lipids make up approximately 50% of the mass of most cell membranes. The lipids that are found in the cell membrane are called phospholipid. Phospholipid are the predominant lipids of cell membrane. Phospholipids aggregate or self-assemble when mixed with water, but in a different manner than the soaps and detergents. Because of the two pendant alkyl chains in phospholipids and the unusual mixed charges in their head groups, micelle formation is unfavorable relative to a bilayer structure.
Fatty acids are another type of lipid. The common feature of fatty acids is that they are all esters of moderate to long chain fatty acids. Two polyunsaturated fatty acids, linoleic and linoleic, are designated "essential" because their absence in the human diet has been associated with health problems, such as scaly skin, stunted growth and increased dehydration. These acids are also precursors to the prostaglandins, a family of physiologically potent lipids present in minute amounts in most body tissues.
Another group of lipids is soups and detergents these lipids are also known as carboxylic acids. Fatty acids made up of ten or more carbon atoms are nearly insoluble in water, and because of their lower density, float on the surface when mixed with water. Unlike paraffin or other alkanes, which tend to puddle on the water’s surface, these fatty acids spread evenly over an extended water surface, eventually forming a monomolecular layer in which the polar carboxyl groups are hydrogen bonded at the water interface, and the hydrocarbon chains are aligned together away from...
