Is a class of phospholipids which incorporate choline

Obtained from a variety of sources such as egg yolk or soya beans

They are extracted using hexane

Member of lecithin group of yellow-brownish fatty substances which occurs in animal and plant tissues

Vital substance found in every cell of the human body

Scientists have proved that phosphatidycholine slows down age related process and improves brain function and memory capacity in dementia

Liver repair

Can be injected so it can be an alternative to liposuction

Tristearin - Type of lipid – Triglyceride Formula of Tristearin C57H110O6Stearin or tristearin, or glycerol tristearate is a triglyceride derived from three units of stearic acid. Most triglycerides are derived from at least two and more commonly three different fatty acids. Main role of Tristearin. A colourless, tasteless and odourless solid ester of glycerol and steric acid. Found is most animal and vegetables fats and oils such as tallow, palm-nut and coconut oils. Used in the manufacture of soaps, candles and adhesives and for textile sizing. Also called Stearin. It is mild and non-irritant on skin which is why it is used in health care products.

is a key structural componet of cellular membranes.
It has an important role in the transport of fats throughout the blood stream.
Choline is a crucial component of acetylcholine, a neurotransmitter essential for normal brain function.

Main role:

Phospholipids consist of a hydrophilic (or 'water loving') head and a hydrophobic (or 'water fearing') tail. Phospholipids like to line up and arrange themselves into two parallel layers, called a phospholipid bilayer. This layer makes up your cell membranes and is critical to a cell's ability to function.

Other roles:

1. There are two important phospholipids, Phosphatidylcholine and Phosphatidylserine found the cell membrane without which cell cannot function normally.

1. Phospholipids are also important for optimal brain health as they found the cell membrane of brain cells also which help them to communicate and influence the receptors function. That is the reason food stuff which is rich in phospholipids like soy, eggs and the brain tissue of animals are good for healthy and smart brain.

1. Phospholipids are the main component of cell membrane or plasma membrane. The bilayer of phospholipid molecules determine the transition of minerals, nutrients, and drugs in and out of the cell and affect various functions of them.

1. As phospholipids are main component of all cell membrane, they influence a number of organs and tissues, such as the heart, blood cells and the immune system. As we grown up the amount of phospholipids decreases and reaches to decline.

1. Phospholipids present in cell membrane provide cell permeability and flexibility with various substances as well its ability to move fluently. The arrangement of phospholipid molecules in lipid bilayer prevent amino acids, carbohydrates, nucleic acids, and proteins from moving across the membrane by diffusion. The lipid bi-layer is usually help to prevent adjacent molecules from sticking to each other.

1. The selectivity of cell membrane form certain substances are due to the presence of hydrophobic and hydrophilic part molecules and their arrangement in bilayer. This bilayer is also maintained the normal pH of cell to keeps it functioning properly.

1. Phospholipids are also useful in the treatment of memory problem associated with chronic substances as they improve the ability of organism to adapt the chronic stress.

Cholesterol
Type of Lipid
Steroid
Main roles of Cholesterol
Cholesterol is responsible for preventing crystallisation of fatty acids and provides optimal temperature to maintain the desired fluidity of phospholipids in the cell membrane. It is also responsible for proper synthesis of neurotransmitters, which is essential for protagation of nerve impulses through neurons. Cholesterol plays an important role in synthesis of vitamin D3 which is responsible for bone calcification.
Other roles
Source of energy, maintenance of our body energy, protection of internal organs, modulation the fluidity of cell membranes.
Fun Facts

# data[].attributes.body
Cholesterol is a sterol.
It is an essential structural component of all animal cell membranes.
It maintains structural integrity and fluidity.
Your body needs cholesterol to make hormones, vitamin D, and substances that help you digest food.
Your body produces all you need, however, some cholesterol is also found in food.
Cholesterol travels through your blood in small packages called lipoproteins. These are made of fat on the inside and proteins on the outside.
Low-density lipoproteins (LDL) are sometimes called bad cholesterol. If you have a high level, they can build up in your arteries.
High-density lipoproteins (HDL) is called good cholesterol. Its role is to carry cholesterol from other parts of your body back to your liver.
High levels of LDLs in your blood can cause a build up of plak (cholesterol, fat, calcium and other substances) this can cause coronary heart disease.

It is a triglyceride derived from three units of stearic acid.

Plays an important role in metabolism as energy sources and transports dietary fats.

Hardening agent used in the manufacturing of candles and soap,

stearin is a colourless crystalline ester of stearic acid used as a tablet and capsule lubricant and as an emulsifying agent.

stearin is obtained from animal fats created as a by-product of processing beef. it can also be found in some tropical plants.
