What are the three parts of a phospholipid?
Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic.
What is a phospholipid composed of?
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).
What are the 3 building blocks of phospholipids?
The building blocks of a phospholipid include two fatty acid tails, the glycerol backbone and a phosphate head.
What 3 elements must lipids contain?
Lipids are composed of carbon, hydrogen and oxygen atoms, and in some cases contain phosphorus, nitrogen, sulfur and other elements.
Which of the following is not a component of a phospholipid?
Which of the following is not a component of a phospholipid? Explanation: A phospholipid is composed of four components: a fatty acid platform, phosphate, alcohol attached to a phosphate and a platform of glycerol on which phospholipid built. Protein is incorrect as protein does not take part in phospholipid formation.
What characteristic of phospholipids makes them essential components of cell membranes?
Phospholipids, arranged in a bilayer, make up the basic fabric of the plasma membrane. They are well-suited for this role because they are amphipathic, meaning that they have both hydrophilic and hydrophobic regions. Chemical structure of a phospholipid, showing the hydrophilic head and hydrophobic tails.
What are phospholipids composed of quizlet?
A phospholipid is composed of a hydrophilic phosphate head and two hydrophobic fatty acid tails. The phosphate heads face outwards where they are able to attract water and the hydrophobic tails are in between which repel water.
What organelle is composed of a phospholipid bilayer?
Mitochondria are double-membraned organelles that contain their own ribosomes and DNA. Each membrane is a phospholipid bilayer embedded with proteins. Eukaryotic cells may contain anywhere from one to several thousand mitochondria, depending on the cell's level of energy consumption.
What is composed of phospholipids and other embedded molecules?
Plasma membranes enclose and define the borders between the inside and the outside of cells. They are typically composed of dynamic bilayers of phospholipids into which various other lipid soluble molecules and proteins have also been embedded.
How are the phospholipid molecules arranged in the membrane?
The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer, with a hydrophobic, or water-hating, interior and a hydrophilic, or water-loving, exterior. Each phospholipid molecule has a head and two tails.
How many carbons are in a phospholipid?
A phospholipid molecule (Figure 2) consists of a three-carbon glycerol backbone with two fatty acid molecules attached to carbons 1 and 2, and a phosphate-containing group attached to the third carbon.
What are phospholipids quizlet?
Phospholipids are amphipathic molecules that make up the bilayer of the plasma membrane and keep the membrane fluid. ... Phospholipids are major components of the plasma membrane, the outermost layer of animal cells.
What are the 3 main types of lipids?
The three main types of lipids are triacylglycerols (also known as triglycerides), phospholipids, and sterols.
What are the 3 functions of lipids?
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 3 examples of lipids?
Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein.
