What are the two main types of lipids?
There are two classes of phospholipids. The first are the glycerophospholipids, which are themselves subdivided into two groups. Phosphatides, is molecules composed of glycerol substituted with two fatty acid esters. Three alcohols that form phosphatides are choline, ethanolamine, and serine.
Lipids can be categorized into three main types.
- Triglycerides. Triglycerides are lipids you obtain from food sources of fat, such as cooking oils, butter and animal fat.
- Steroids. Steroids are a type of lipid that includes hormones and cholesterol.
- Getting Your Lipid Levels Tested.
- Any of a group of organic compounds, including the fats, oils, waxes, sterols, and triglycerides, that are insoluble in water but soluble in common organic solvents, are oily to the touch, and together with carbohydrates and proteins constitute the principal structural material of living cells.
- Unsaturated fats are typically liquid at room temperature. They differ from saturated fats in that their chemical structure contains one or more double bonds. They can be further categorized as: Monounsaturated fats: This type of unsaturated fat contains only one double bond in its structure.
- Lipids have several important roles in the body, providing: a source and store of energy. an important part of the membrane surrounding every body cell. the basic building blocks from which several hormones (chemical messengers) and bile acids (digestive juices) are made.
Lipids, also known as fats, play many important roles in your body, from providing energy to producing hormones. You wouldn't be able to digest and absorb food properly without lipids. Of course, eating more fat than you need can lead to weight gain, but in proper amounts lipids are a healthy part of your diet.
- The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is found in the nucleus of eukaryotes and in the chloroplasts and mitochondria.
- The main molecule that starts the structure of a triglyceride is glycerol. Glycerol is a three-carbon molecule with three hydroxyl groups on them. These hydroxyl groups are the site of an ester reaction with three fatty acid molecules.
- Lipids, or fats, are digested and absorbed in the small intestine. In this lesson, you will learn how bile salts emulsify fat so pancreatic lipase can digest it. You will also learn how fats first enter lymphatic capillaries, called lacteals, before entering your blood circulation.
