Unit 5: Lipids and the Athlete: Energy and Growth Factors Flashcards
Lipids
The third major category of macronutrients, and they are made of carbon, hydrogen and oxygen and involved with the storage and supply of fat soluble vitamins.
Triglycerides
A type of fat in your blood, triglycerides can contribute to the hardening and narrowing of your arteries if levels are too high.
Oils
Lipids that are liquid at room temperature, oils come from many different plants and from seafood.
Saturated Fatty Acids
Fatty acids that have no double bonds.
Unsaturated Fatty Acids
Unsaturated fats are liquid
at room temperature.
Monounsaturated Fatty Acids
The unsaturated fats that only have one double bond.
Polyunsaturated Fatty Acids
The unsaturated fats that have more than one double bond. usually liquid at room temps.
Solid Fats
Fats that are usually not liquid at room temperature.
High Density Lipoprotein
HDL is a compound made up of fat and protein that carries cholesterol in the blood to the liver, where it is broken down and excreted. Commonly called “good” cholesterol, high levels of HDL cholesterol are linked to a lower risk of heart disease.
Phospholipids
A second major class of lipids, next to fatty acids/ triglycerides. They are a major structural lipid in all organisms and part of every living cell.
Lipotropic
A substance that prevents fatty buildup in the liver and helps the body metabolize fat more efficiently.
Bile
A substance secreted by the liver that is essential for the digestion and absorption of fats.
Cholesterol
A member of a group of fats called sterols. Cholesterol is made by the body and only occurs naturally in foods of animal origin.
Trans Fatty Acids
A type of fat produced when liquid fats (oils) are turned into solid fats through a chemical process called hydrogenation.
Hydrogenation
A chemical process that turns liquid fats (oils) into solid fats, hydrogenation creates a fat called trans fatty acid.
