What are the subunits of each macromolecule?
Types of biological macromolecules
| Biological macromolecule | Building blocks |
|---|---|
| Carbohydrates | Monosaccharides (simple sugars) |
| Lipids | Fatty acids and glycerol |
| Proteins | Amino acids |
| Nucleic acids | Nucleotides |
What are the 4 major macromolecules and their subunits?
As we’ve learned, there are four major classes of biological macromolecules:
- Proteins (polymers of amino acids)
- Carbohydrates (polymers of sugars)
- Lipids (polymers of lipid monomers)
- Nucleic acids (DNA and RNA; polymers of nucleotides)
What make up each of the macromolecules?
There are four classes of macromolecules (polysaccharides or carbohydrates, triglycerides or lipids, polypeptides or proteins, and nucleic acids such as DNA & RNA). Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON).
What do the 4 macromolecules make up?
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions. Combined, these molecules make up the majority of a cell’s dry mass (recall that water makes up the majority of its complete mass).
What are the subunits that make up proteins?
In the case of proteins, those subunits are amino acids. Any amino acid features a central carbon atom that is connected to an amino group, a hydrogen atom, and a carboxyl group.
Are the subunits of proteins?
Single chains of amino acids that are the units of multimeric PROTEINS. Multimeric proteins can be composed of identical or non-identical subunits. One or more monomeric subunits may compose a protomer which itself is a subunit structure of a larger assembly.
What are the 4 macromolecules monomers?
Comparing the Biological Macromolecules
| Macromolecule | Basic Formula, key features | Monomer |
|---|---|---|
| Proteins | CHON −NH2 + −COOH +R group | Amino acids |
| Lipids | C:H:O Greater than 2:1 H:O (carboxyl group) | Fatty acid and glycerol |
| Carbohydrates | C:H:O 1:2:1 | Monosaccharides |
| Nucleic Acids | CHONP pentose, nitrogenous base, phosphate | Nucleotides |
Which macromolecule is composed of C H O?
Comparing the Biological Macromolecules
| Macromolecule | Basic Formula, key features | Uses |
|---|---|---|
| Lipids | C:H:O Greater than 2:1 H:O (carboxyl group) | Energy storage; Protection; Chemical messengers; Repel water |
| Carbohydrates | C:H:O 1:2:1 | Energy storage; Structure |
| Nucleic Acids | CHONP pentose, nitrogenous base, phosphate | Genetic information |
What subunits make up proteins?
Proteins are made of subunits called amino acids and are used to build cells and do much of the work inside organisms. They also act as enzymes helping to control metabolic reactions in organisms. Amino acids contain two functional groups, the carboxyl group (-COOH) and the amino group (-NH2).
What elements make up lipids?
Lipids are composed of carbon, hydrogen and oxygen atoms, and in some cases contain phosphorus, nitrogen, sulfur and other elements.
What are the 4 types of macromolecules and their functions?
Nucleic acids: Stores and transfers info.
What two subunits are ribosomes made of?
Ribosomes are made out of two things: a small ribosomal subunit that reads the mRNA, while the large subunit joins amino acids to form a polypeptide chain. Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and a variety of proteins.
What subunits make up biomolecules?
Monomers are small subunits that compose larger molecules or macromolecules. Biomolecules are large molecules present in living organisms. There are four major classes of biomolecules: carbohydrates, lipids, proteins and nucleic acids. Each with monomers: monosaccharides, glycerol and fatty acids, amino acids and nucleotides, respectively.
Are enzymes made up of subunits?
Enzymes are complex compounds composed of starch. Each enzyme has a characteristic shape. Enzymes are long, complex fats. Each enzyme is made up of four subunits. Which substance is necessary for synthesis of most materials in an organism? A sample of food containing one type of a large molecule was treated with a specic digestive enzyme.
What are the four groups of macromolecules?
Macromolecules are made up of basic molecular units. They include the proteins (polymers of amino acids), nucleic acids (polymers of nucleotides), carbohydrates (polymers of sugars) and lipids (with a variety of modular constituents). The four groups are Proteins, Lipids, Carbohydrates, and Nucleic Acids.
