What are phospholipids made up of?
Phospholipids are amphiphilic molecules composed of a glycerol backbone carrying a hydrophilic polar head group and two hydrophobic fatty acyl tails (Van Meer et al., 2008; Vance and Vance, 2002).
What are lipids 3 major groups?
The three primary types of lipids are phospholipids , sterols, and triglycerides . They each play a different role in the body.
What 3 compounds make up lipids?
There are three main types of lipids: triglycerides, phospholipids, and sterols.
What functional groups are in phospholipids?
In general, phospholipids are composed of a phosphate group, two alcohols, and one or two fatty acids. On one end of the molecule are the phosphate group and one alcohol; this end is polar, i.e., has an electric charge, and is attracted to water (hydrophilic).
Where are phospholipids made?
Bulk membrane lipid biogenesis in primary cells largely occurs in the endomembrane compartment, which includes the domains of the ER and Golgi apparatus. Specialized phospholipids are synthesized in mitochondria or perosixomes.
What are the three classes of lipids quizlet?
Three types of lipids are found in foods and in body cells and tissues: Triglycerides, Phospholipids, and sterols. Contain three fatty acid molecules and one glycerol molecules.
What are the major groups of lipids?
In Summary: Lipids Major types include fats and oils, waxes, phospholipids, and steroids. Fats are a stored form of energy and are also known as triacylglycerols or triglycerides. Fats are made up of fatty acids and either glycerol or sphingosine.
What enzymes make phospholipids?
Fatty Acid and Phospholipid Biosynthesis in Prokaryotes The 27.6 kDa enzyme phosphatidate cytidylyltransferase (or CDP-diacylglycerol synthase) catalyses the conversion of phosphatidic acid to a mixture of CDP-diacylglycerol and dCDP-diacylglycerol.
What are the 3 major groups types of lipids and what are their main functions quizlet?
Lipids perform three primary biological functions within the body: they serve as structural components of cell membranes, function as energy storehouses, and function as important signaling molecules. The three main types of lipids are triacylglycerols (also called triglycerides), phospholipids, and sterols.
What are the components of a phospholipid molecule?
Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol.
Fatty acids are long chains that are mostly made up of hydrogen and carbon, while phosphate groups consist of a phosphorus molecule with four oxygen molecules attached. These two components of the phospholipid are connected via a third molecule, glycerol.
How are triglycerides and phospholipids alike and different?
Like fats, they are composed of fatty acid chains attached to a glycerol backbone. Unlike triglycerides, which have three fatty acids, phospholipids have two fatty acids that help form a diacylglycerol.
Which is the parent molecule of phosphatidic acid?
Phospholipids contain glycerol, two fatty acids, a phosphate and a basic component. Phosphatidic acid, the parent molecule of phospholipids, is formed by the joining of 3-glycerol-phosphate and a diglyceride; then the base (choline or other) is linked to the phosphate group of phosphatidic acid to form phosphatidyl choline (or other phospholipids).
