This hypothesis says that:

• some fatty acids (notably trans and saturated fatty acids) increase blood cholesterol levels, particularly the ‘bad’ LDL cholesterol levels,
• increases in blood cholesterol levels, again particularly LDL cholesterol levels, increase the risk of CVD,
• therefore, consumption of trans and saturated fatty acids increase the risk of CVD.

What is the role of the pancreatic lipase in the lipid bond?

The pancreatic lipase acts at the ester bond, hydrolyzing the bond and "releasing" the fatty acid. In triglyceride form, lipids cannot be absorbed by the duodenum. Fatty acids, monoglycerides (one glycerol, one fatty acid), and some diglycerides are absorbed by the duodenum, once the triglycerides have been broken down.

What are fats named after?

Polyunsaturated fatty acids are two or more pairs of hydrogen atoms short of saturation; two examples are omega-3 and omega-6 fatty acids. Polyunsaturated fat is another type of unsaturated fat, and they too can help lower your cholesterol levels when you consume them instead of saturated fats. Foods that contain polyunsaturated fats include many vegetables oils and fatty fish such as salmon, mackerel, herring and trout.

What are hydrogenated trans fats?

You may be wondering where hydrogenated trans fats fit into the picture. These trans fats are not naturally occurring; an industrial process adds hydrogen to liquid vegetable oils, making them solid at room temperature. The American Heart Association reports that trans fats raise your bad LDL cholesterol while lowering your good HDL levels, and they also increase your risk of developing heart disease, stroke and type 2 diabetes. Trans fatty acids are found in fried foods and commercial baked goods such as cookies, donuts and crackers, as well as in processed foods and many margarines.

How does triglycerides affect your health?

Triglycerides are fats that you absorb from food or create in the liver, often from sugars. High triglyceride levels increase the risk of heart disease and diabetes. Built-up triglycerides can damage and clog blood vessels, reduce fat burning in cells, and increase fat storage in the liver. High levels are often accompanied by an increase in LDL cholesterol and a drop in HDL cholesterol, a detrimental combination for your heart and overall health. Your diet and weight have a huge impact on your levels. Diets high in calories, high-carbohydrate, low-fat diets, and obesity increase triglycerides. Vitamin D deficiency, smoking, an underactive thyroid, inflammation, genetics, and certain medications and diseases can also raise your levels.

High levels of triglycerides can increase your risk of obesity, heart disease, diabetes, and other chronic health conditions. Read on to find out if your levels are within the normal range and to learn which factors and conditions can increase triglyceride levels.

What enzyme is used to burn triglycerides?

Burning triglycerides for fuel requires a special enzyme ( lipoprotein lipase ), which is found in the muscles [ 1 ]. Triglycerides are fats you get through diet, store in fat tissue, and burn as fuel when needed. The liver can make triglycerides from sugar and other fats.

Does obesity cause high triglycerides?

Directly tied to high-calorie diets and overeating, obesity is often associated with high triglyceride levels. People with obesity also often have high “bad” LDL cholesterol and low “good” HDL cholesterol, which burdens blood vessels. This combination of factors increases chronic inflammation and the risk of heart disease and diabetes [ 22 ].

Does triglyceride increase with overeating?

Triglyceride levels increase with a positive energy-intake balance (overeating). In other words, when you eat more than your body needs, the surplus is transformed into fat, including triglycerides.

Overview

Classification

Fats can be classified according to the lengths of the carbon chains of their constituent fatty acids. Most chemical properties, such as melting point and acidity, vary gradually with this parameter, so there is no sharp division. Chemically, formic acid (1 carbon) and acetic acid (2 carbons) could be viewed as the shortest fatty acids; then triformin would be the simplest triglyceride. However, the terms "fatty acid" and "fat" are usually reserved for compounds with su…
