What 2 things make up triglycerides?
Triglycerides are lipid compounds composed of a glycerol esterified to 3 fatty acid chains of varying length and composition. These fatty acid chains can be saturated or unsaturated, and the chemical composition of each chain is different.
What two subunits make up a lipid triglyceride?
Fats are made of a glycerol (alcohol) and three fatty acid chains. This subunit is called a triglyceride.
What are the 2 subunits of lipids?
Biological lipids originate entirely or in part from two distinct types of biochemical subunits or “building blocks”: ketoacyl and isoprene groups.
Which 3 elements make up triglycerides?
Chemical composition
- A triglyceride is composed of glycerol and three fatty acids.
- Mono- and diglycerides are mono- and diesters of fatty acids and glycerol.
- Free fatty acids are the unattached fatty acids present in a fat.
What is triacylglycerol made of?
Triacylglycerol is composed of three fatty acids esterified to a glycerol molecule (Figure 4). The physical properties of the triacylglycerol are determined by the specific fatty acids esterified to the glycerol moiety and the actual position the fatty acids occupy.
What 2 subunits make up fats?
Fats and oils A fat molecule consists of two kinds of parts: a glycerol backbone and three fatty acid tails. Glycerol is a small organic molecule with three hydroxyl (OH) groups, while a fatty acid consists of a long hydrocarbon chain attached to a carboxyl group.
What are the three subunits of triglyceride?
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.
What subunits make up carbohydrates?
Carbohydrates are used by the body for energy and structural support in cell walls of plants and exoskeletons of insects and crustaceans. They are made of smaller subunits called monosaccharides. Monosaccharides have carbon, hydrogen, and oxygen in a 1:2:1 ratio.
How is a phospholipid different from a triglyceride?
Like triglycerides, phospholipids have a glycerol backbone. But unlike triglycerides, phospholipids only have two fatty acid molecules attached to the glycerol backbone, while the third carbon of the glycerol backbone is bonded to a phosphate group—a chemical group that contains the mineral phosphorus.
How are triglycerides made?
A triglyceride is formed when the three hydroxyls (OH-) groups of a single glycerol molecule react with the carboxyl group (COOH-) of three fatty acids by forming ester bonds.
Where are triglycerides made?
The source of triglycerides Food is one source of triglycerides. Your liver also makes them. When you eat extra calories — especially carbohydrates — your liver increases the production of triglycerides. When you consume — or your body creates — excess triglycerides, they’re stored in fat cells for later use.
What are the monomer units of triglycerides?
Triglycerides. The monomers of triglycerides are fatty acids and glycerol. Glycerol is a type of alcohol. Triglycerides are made up of monomers of glycerol molecules each bonded to three fatty acid “tails.”.
What is the common name for triglycerides?
A triglyceride (TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids (from tri- and glyceride). Triglycerides are the main constituents of body fat in humans and other vertebrates, as well as vegetable fat.
What are the properties of triglycerides?
Triglycerides are esters of fatty acids and a trifunctional alcohol – glycerol (IUPAC name is 1,2,3-propantriol). The properties of fats and oils follow the same general principles as already described for the fatty acids. The important properties to be considered are: melting points and degree of unsaturation from component fatty acids.
What do triglycerides consist of?
Triglycerides are comprised of long chains of glycerol molecules, each of which is attached to three molecules of fatty acids (hence the name, “triglyceride”). Triglycerides are named according to the length of the glycerol chains they contain.
