What kind of molecule is represented in the diagram
What kind of molecule is represented in the diagram glycerol and fatty acid?
A fat molecule, such as a triglyceride, consists of two main components—glycerol and fatty acids. Glycerol is an organic compound with three carbon atoms, five hydrogen atoms, and three hydroxyl (–OH) groups.
What kind of molecule is glycerol?
A fat molecule consists of two main components: glycerol and fatty acids. Glycerol is an alcohol with three carbons, five hydrogens, and three hydroxyl (OH) groups. Fatty acids have a long chain of hydrocarbons with a carboxyl group attached and may have 4-36 carbons; however, most of them have 12-18.
Which structural formulas represent carbohydrate molecules?
Carbohydrates can be represented by the stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule. Therefore, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. The origin of the term “carbohydrate” is based on its components: carbon (“carbo”) and water (“hydrate”).
Which macromolecules are often made of three fatty acids bound to a glycerol molecule?
Lipids are the fat molecules of biology and are frequently composed of fatty acids. Glycerol is a short 3-carbon chain that is often used to bind different fatty acids together and form lipid structures. When glycerol binds to three fatty acid chains, it forms a triglyceride.
What structure represents a lipid molecule?
A natural lipid molecule in our body, known as triacylglycerols, or triglycerides (TGs), is made up of one glycerol molecule that is joined to three molecules of fatty acids (saturated/unsaturated or both) through ester bonds.
What is triglyceride molecule?
Triglycerides are esters in which three molecules of one or more different fatty acids are linked to the alcohol glycerol; they are named according to the fatty acid components; e.g., tristearin contains three molecules of stearic acid, and oleodistearin, one of oleic acid and two of stearic acid.
Which of the following is composed of a glycerol molecule bound to three fatty acids?
Triglycerides. Triglycerides are composed of a glycerol molecule bound to three fatty acids and are digested by pancreatic lipase. Triglycerides are a major component of very-low-density lipoprotein (VLDL) and serve as a source of energy.
How do you draw a triglyceride molecule?
Which of the four macromolecules is often made up of glycerol and fatty acids?
Lipids are a class of macromolecules that are nonpolar and hydrophobic in nature. Major types include fats and oils, waxes, phospholipids, and organic compounds. Fats and oils are a stored form of energy and can include triglycerides. Fats and oils are usually made up of fatty acids and glycerol.
What type of molecule is represented by the model below a glycerol molecule with three fatty acid chains attached to it?
Triglycerides comprise three fatty acids bonded to glycerol, yielding a hydrophobic molecule. Phospholipids contain both hydrophobic hydrocarbon chains and polar head groups, making them amphipathic and capable of forming uniquely functional large scale structures.
Are molecules composed of a glycerol and three fatty acids quizlet?
The major form of lipid in food and in the body. They consist of three fatty acids attached to a glycerol molecule.
What functional group is present in a triglyceride?
It has a glycerol backbone with three fatty acids linked by an ester, so the functional group is Ester.
What is a triglyceride structure?
Triglycerides are tri-esters consisting of a glycerol bound to three fatty acid molecules. Alcohols have a hydroxyl (HO–) group. Organic acids have a carboxyl (–COOH) group. Alcohols and organic acids join to form esters.
What is TAG lipid?
Triacylglycerols (TAGs) are chemical compounds that are major components of vegetable oils and animal fats. TAG are formed by one molecule of glycerol esterified by fatty acid molecules in all three OH groups. … Most natural fats contain a complex mixture of different TAGs and therefore melt in a wide temperature range.
How does a glycerol molecule differ from a carbohydrate molecule?
In Fats and carbohydrates? … How does a glycerol molecule differ from a carbohydrate molecule ? Carbs are ring-shaped and glycerol is not they also have different H:O ratios. How does a fatty acid molecule differ from a carbohydrate molecule ?
What is the structure of phospholipids?
The structure of a phospholipid molecule contains two hydrophobic tails of fatty acids and one hydrophilic head of phosphate moiety, jointed together by an alcohol or glycerol molecule . Due to this structural arrangement, PLs form lipid bilayers and are a key component of all the cell membranes.
What is fatty acid structure?
Generally, a fatty acid consists of a straight chain of an even number of carbon atoms, with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group (―COOH) at the other end. … A few fatty acids have branched chains; others contain ring structures (e.g., prostaglandins).
Is glycerol a lipid?
The basic unit of lipids is a triglyceride, synthesised from glycerol (propane-1,2,3-triol) and fatty acids. Glycerol is a type of alcohol. Alcohols are organic compounds. … Glycerol is a trihydric alcohol, which means each molecule has three hydroxyl groups.
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 is the protein shown in the diagram associated with the plasma membrane?
How is the protein shown in the diagram associated with the plasma membrane? … It is attached to another protein that is a transmembrane protein. It is associated with one layer of the lipid bilayer.
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.
