What are the different types of lipids?
lipids relate to a large class of organic chemical compounds, which were sometimes described as a third food group after proteins and carbohydrates. They are popularly associated with fats, but there are many other types of lipids. With the stunning variety found in nature, biochemists could not agree on the system of their categorization. In 2005, the international group of academics designed eight classifications based partly on the molecular form of lipids, but also on the apparent natural function of the chemical. Some of their signature characteristics are shared together in most other types of lipids together. Their "spine" is a long, direct chain of carbon and hydrogen atoms, usually an even number from 4 to 48. One end of the chain is considered hydrophobic because the fats are insoluble and cannot break and dissolve in water.
oleic acid is one of the dominant fatty acids in olivolej and other vegetable oils. These types of lipids are also most abundant in human tissuefat. Muscle tissue relies on the storage medium of fuel. Some chemists argued that more complex lipids can be constructed as fatty acid derivatives or imitating their basic functional characteristics.
glycerolipids are a stronger fuel storage, while the spine is connected to one or more oxygen and hydrogen atoms. Triglycerides with three such hydroxyl couples are also abundant in the human body. Further to connect the grouping of various chemicals associated with phosphorus atom creates phospholipids. While one end of the chain remains repelled into the water, the other end attracts water or is hydrophilic. Phospholipids are key components of selective semi -freeness of all membranes of all living cells, the ability of the barrier to keep water to retain water.
fatty acids that attach to a complex organic compound called sphinosinficed as sphinolipids. They are also primarily found in cell membranes and are expected to play a role in identifying and communicating with other cells. Saccharolipids are attached by simple sugar such as glucose. Prenol is a natural alcohol found in citrus fruits and other meals. Vitamin E and vitamin K are examples of prenol lipids.
Sterol lipids are a group of fatty acids connected to sterols or steroid alcohols. It is also said that they are ampifly - repulsive and attracting water - and an important structural component of cell membranes. Cholesterol is the best known example. There are some types of lipids extracted from animal or plant sources with a significant healing value for humans. One productive category is polyketis, secondary compounds derived from metabolization and changes in molecular structures lipids.
