There are several types of lipids, of which cholesterol is the best-known. Cholesterol is actually part lipid, part protein. This is why the different kinds of cholesterol are called lipoproteins. Another type of lipid is a triglyceride.

The main simple lipids are triglycerides (also known as triacylglycerols), steryl esters, and wax esters. Hydrolysis of these lipids yields glycerol and fatty acids, sterols and fatty acids, and fatty alcohols plus fatty acids, respectively.

Lipids play many roles in cells, including serving as energy storage (fats/oils), constituents of membranes (glycerophospholipids, sphingolipids, cholesterol), hormones (steroids), vitamins (fat soluble), oxygen/ electron carriers (heme), among others.

The key difference between simple and complex lipids is that simple lipids are esters of fatty acids with alcohols and do not carry other molecules while complex lipids are fatty acids with alcohols and other molecules such as phosphates, nitrogenous base, etc.

Derived fats like sterols (cholesterols), ketone bodies, hydrocarbons, terpenes, carotenoids etc, are obtained by the hydrolysis of simple lipids and compound lipids. Neutral fats (fats and oils) are not synthesised by this method.

A simple lipid is a fatty acid ester of different alcohols and carries no other substance. Fats: esters of fatty acids with glycerol. Oils are fats in the liquid state. Fats are also called triglycerides because all the three hydroxyl groups of glycerol are esterified.

Lipids are an essential component of the cell membrane. The structure is typically made of a glycerol backbone, 2 fatty acid tails (hydrophobic), and a phosphate group (hydrophilic). As such, phospholipids are amphipathic. Another type of lipid is wax. Waxes are esters made of long-chain alcohol and a fatty acid.

Lipids are a family of organic compounds that are mostly insoluble in water. Composed of fats and oils, lipids are molecules that yield high energy and have a chemical composition mainly of carbon, hydrogen, and oxygen.

The most common building blocks of lipids are fatty acids. A fatty acid is a compound consisting of a hydrocarbon chain and a carboxyl group (−COOH) at one end. Typically, fatty acids are bound to a glycerol molecule which consists of three hydroxyl groups (-OH), each bound to a carbon atom.

Lipids are transported from the enterocyte into blood by a mechanism distinctly different from what we’ve seen for monosaccharides and amino acids. Once inside the enterocyte, fatty acids and monoglyceride are transported into the endoplasmic reticulum, where they are used to synthesize triglyeride.

Triacylglycerols (also known as triglycerides) make up more than 95 percent of lipids in the diet and are commonly found in fried foods, vegetable oil, butter, whole milk, cheese, cream cheese, and some meats. Naturally occurring triacylglycerols are found in many foods, including avocados, olives, corn, and nuts.

Most people have high levels of fat in their blood because they eat too much high-fat food. Some people have high fat levels because they have an inherited disorder. High lipid levels may also be caused by medical conditions such as diabetes, hypothyroidism, alcoholism, kidney disease, liver disease and stress.

What happens if my lipids are too high? An excess amount of blood lipids can cause fat deposits in your artery walls, increasing your risk for heart disease.

Our blood lipids are just like oil. In order to circulate in the watery blood, these lipids (cholesterol and triglycerides) are packaged along with proteins. These packages are called lipoproteins.

Triglycerides are not a type of cholesterol, but they are part of a lipoprotein panel (the test that measures cholesterol levels). A normal triglyceride level is below 150 mg/dL….Men age 20 or older:

Cells are the building blocks of all organisms and lipids are considered the building blocks of cells. Without lipids, your cells will not be able to survive.

If you don’t get enough fat in your diet, you may notice symptoms such as dry rashes, hair loss, a weaker immune system, and issues related to vitamin deficiencies. To help maintain good health, most of the fats you eat should be monounsaturated or polyunsaturated fats.

Wolman’s disease, also known as acid lipase deficiency, is a severe lipid storage disorder that is usually fatal by age 1.
