What type of macromolecule is triglyceride?
What type of macromolecule is triglyceride?
Triglycerides are macromolecules called lipids, better known as fats or oils. Triglycerides are named for the monomer components they contain. “Tri” means three, and triglycerides are built from monomers of three fatty acids bonded to a glycerol.
What type of macromolecule is phospholipid?
Lipids
Types of biological macromolecules
| Biological macromolecule | Building blocks | Examples |
|---|---|---|
| Lipids | Fatty acids and glycerol | Fats, phospholipids, waxes, oils, grease, steroids |
| Proteins | Amino acids | Keratin (found in hair and nails), hormones, enzymes, antibodies |
| Nucleic acids | Nucleotides | DNA, RNA |
Is triglyceride a phospholipid?
Phospholipids are similar to triglycerides, but they do vary slightly in form and function. While triglycerides have glycerol and three fatty acids, phospholipids have glycerol, two fatty acids and a phosphate. Phosphates are molecules with charges and have oxygen and phosphorus. Fat cells do not store phospholipids.
Is triglyceride an example of a lipid?
triglyceride, any one of an important group of naturally occurring lipids (fat-soluble components of living cells).
Is phospholipid a monomer or polymer?
Fatty acids are lipid monomers that consist of a hydrocarbon chain with a carboxyl group attached at the end. Fatty acids form complex polymers such as triglycerides, phospholipids, and waxes.
What is the difference between a triglyceride and a phospholipid?
Phospholipids are similar to triglycerides with one important difference. The phospholipid is similar to the triglyceride in that it contains fatty acid tails attached to a glycerol backbone. However, the phospholipid contains a organic phosphate zwiterion instead of a third fatty acid tail.
Is phospholipid a macromolecule?
Phospholipids are part of the lipids macromolecule group.
What kind of macromolecule is cellulose?
Comparing the Biological Macromolecules
| Macromolecule | Basic Formula, key features | Examples |
|---|---|---|
| Lipids | C:H:O Greater than 2:1 H:O (carboxyl group) | Butter, oil, cholesterol, beeswax |
| Carbohydrates | C:H:O 1:2:1 | Glucose, Fructose, Starch, Glycogen, Cellulose |
| Nucleic Acids | CHONP pentose, nitrogenous base, phosphate | DNA, RNA |
Do triglycerides have a phosphate group?
Phospholipid: Phospholipids are composed of a phosphate group attached to the glycerol backbone. Triglyceride: Triglycerides has no phosphate groups attached to the glycerol backbone.
Do phospholipids have a phosphate group?
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).
Is phospholipid a lipid or carbohydrate?
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.
Is triglyceride a carbohydrate lipid or protein?
Triglycerides are classified as simple lipids because they are formed from just two types of compounds: glycerol and fatty acids. In contrast, complex lipids contain at least one additional component, for example, a phosphate group (phospholipids) or a carbohydrate moiety (glycolipids).
What is the difference between triglycerides and phospholipids?
Triglycerides and phospholipids are two groups of lipids A condensation reaction (removal of water) between a glycerol molecule and fatty acid forms an ester bond Hydrolysis, addition of a water molecule, of a triglyceride form fatty acids and glycerol.
What are the hydrophilic and hydrophobic parts of phospholipids?
The hydrophilic head of the phospholipid molecule is composed of a phosphate group and a glycerol backbone. The hydrophobic tail of the phospholipid molecule is composed of two fatty acid chains. These fatty acid chains are long chain fatty acids. They repel water. Therefore, they are considered as hydrophobic part of the phospholipid molecule.
Which of the following has no phosphate groups attached to glycerol?
Triglyceride: Triglycerides has no phosphate groups attached to the glycerol backbone. Phospholipid: Phospholipids make up the cell membrane of cells.
How is a triglyceride molecule formed by hydrolysis?
A triglyceride molecule is formed by joining of one molecule of glycerol to three fatty acids combined with glycerol. Each fatty acid is joined and combined with the glycerol forming an ester bond in three condensation reaction. Hydrolysis causes the breakdown of the triglyceride and produces glycerol and three fatty acids.
