What are the subunits of macromolecules?
Most macromolecules are polymers, which are long chains of subunits called monomers. These subunits are often very similar to each other, and for all the diversity of polymers (and living things in general) there are only about 40 – 50 common monomers.
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 are the macromolecules that comprise the living system?
Biological macromolecules are large molecules, necessary for life, that are built from smaller organic molecules. 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.
What are the 4 macromolecules of living things?
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).
What are subunits of carbohydrates?
MONOSACCHARIDES. The monosaccharides (mono = one, saccharide = sugar) are the basic subunits of carbohydrates.
What is the relationship between monomers and polymers?
All monomers have the capacity to form chemical bonds to at least two other monomer molecules. Polymers are a class of synthetic substances composed of multiples of simpler units called monomers. Polymers are chains with an unspecified number of monomeric units.
What are the subunits of lipid?
“The subunits of lipids are fats, oils, waxes, sterols and triglycerides. “
Do lipids have subunits?
What is the subunit of lipids? Fatty acids, glycerol, and sometimes phosphate groups.
Are monomers subunits of polymers?
Monomers are small molecules which may be joined together in a repeating fashion to form more complex molecules called polymers. Sometimes polymers are made from bound groups of monomer subunits (up to a few dozen monomers) called oligomers.
