Chapter 8 Lecture Notes Lipids 1 Chapter 8 Lecture Notes: Lipids Educational Goals 1. Know the factors that characterize a compound as being a lipid. 2. Describe the structure of fatty acids and explain how saturated, monounsaturated, and polyunsaturated fatty acid structures differ from one another. 3.

Properties of Lipids. High energy value. Lipids contain many carbon hydrogen bonds, when these are broken carbon dioxide and water are the final products. They are oxidised in respiration and are three times more efficient at energy storage than carbohydrates; Hydrophobic. Oils are used in the fur / feathers of animals as waterproofing.

Testosterone is an example of a steroid. Steroids that have a hydroxyl group at C3 are called sterols (e.g., cholesterol). Other lipids: Some lipids have structures that do not fit into the other classes. For example, retinol, or vitamin A (see figure), is a polyisoprenoid that our bodies convert to retinal, which is a photoreceptor in the rod ...

Lipids are composed of three fatty acids (usually) covalently bonded to 3-carbon glycerol. The fatty acids are composed of CH 2 units and are hydrophobic/not water-soluble. Some examples of fatty acids are shown in Figure 1. Figure 1. Saturated (top and middle) and unsaturated (bottom) fatty acids.

Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic birds and mammals dry because of their water-repelling nature. Lipids are also the building blocks of many hormones and are an important constituent of the plasma membrane. Lipids include fats, oils, waxes, phospholipids, and steroids.

Examples of Types of Lipids. Many types of lipids are part of your everyday diet. Other types of lipids form naturally in your body. No matter how they get there, lipids are an important part of our lives and our health. Here are some lipid examples that you might discover in your body – and where you can find them in a healthy diet. Fats

-type of structural lipid-consists of a long fatty-acid chain joined to a long alcohol chain-highly waterproof-in plants, wax form a protective coating on the outer surface-forms protective layers in animals-similar in structure to fats and oils, but they are formed w/ a complex alcohol instead of glycerol
Fatty acids are connected to this backbone, so that the lipid as a whole has a polar head and a non-polar tail. The lipid bilayer of the cell membrane consists of two layers of lipids, with the inner and outer surfaces of the membrane made up of the polar head groups, and the inner part of the membrane made up of the non-polar fatty acid tails.
The waxy waterproof layer that cover most plant leaves and stems is called a cuticle. The cuticle is thicker on the upper half of a leaf's surface, and it is waterproof so as the internal areas of ...
Jul 14, 2015 · Lipids Bilayer Plasma Membrane 6. Classification • The lipids are classified as – Simple lipid – Complex lipid – Precursor and derived lipid 7. Simple lipids • Esters of fatty acids with various alcohols. – Fats: Esters of fatty acids with glycerol. Oils are fats in the liquid state.
The study of lipids as a class of molecules within the metabolome is important as they act as signalling and inflammatory molecules, and are known to be significant players in a number of metabolic disorders, cardiovascular disease, oncology, and other disease areas. However, lipids are an extremely complex and diverse group of compounds.
Lipid - Lipid - Waxes: A second group of neutral lipids that are of physiological importance, though they are a minor component of biological systems, are waxes. Essentially, waxes consist of a long-chain fatty acid linked through an ester oxygen to a long-chain alcohol. These molecules are completely water-insoluble and generally solid at biological temperatures. Their strongly hydrophobic ...

Phospholipids The second most common of the three basic lipids. Similar to triacylglycerols, phospholipids have an acid containing phosphorus in place of one of the fatty acids. These lipids appear in all cell membranes. make up only about 2 percent of dietary lipids. They are water-soluble and are found in both plants and animals.
