An exception to this statement is the assembly of lipid molecules, such as fats and oils, which are not formed by polymerization of repeating subunits but rather by condensation reactions between individual fatty acid molecules and glycerol molecules. Lipids do not form polymers in the same way that proteins, nucleic acids, and carbohydrates do.

Which organic reaction produces rubber and plastics?
The polymerization reaction produces rubber and plastics from organic molecules. In this reaction, monomers join together to form long chains of repeating units, creating the polymer structure of rubber and plastics.
Polymer powder is made using a special chemical reaction called a?
polymerization process, where small molecules (monomers) combine to form long chains (polymers). This reaction typically involves the bonding together of many repeating units in a controlled manner to create the desired polymer powder.
What do monomers form?
Monomers are small molecules that can bind together to form larger molecules called polymers. Polymers are made up of repeating units of monomers linked together through chemical bonds. The process of monomers forming polymers is known as polymerization.
Large carbon molecules are built from smaller simpler molecules called?
monomers, which are repeating units that link together to form polymers. This process, known as polymerization, involves the formation of chemical bonds between monomers to create complex carbon-based structures. Examples of large carbon molecules include proteins, carbohydrates, and nucleic acids.
Number-average molecular weight of a polypropylene is 1000000 gmol Compute the number-average degree of polymerization?
Number-average degree of polymerization = (Number-average molecular weight of polymer) / (Molecular weight of repeating unit) For polypropylene, the molecular weight of the repeating unit is 42 g/mol. Thus, degree of polymerization = 1000000 g/mol / 42 g/mol = 23809.52.
Is hydrolysis the synthesis of giant molecules from components of repeating units?
No. Hydrolysis is breaking apart the components of a macromolecule. Dehydration synthesis is the synthesis of macromolecules from components of repeating units.
What are molecules that are long chains of repeating molecules?
polymers
What are the similarities between addition polymerization and condensation polymerization?
Polymerization describes the formation of of large molecules (polymers) with repeating structure from smaller molecules (monomers) . The word polymer comes from Greek words meaning many (poly-) and parts (-mer). Many of the resulting molecules are plastics, so polymer is occasionally used in place of the word plastic, though this is not an accurate usage. Polymerization is an all-encompassing term that describes formation of polymers by any method.There are two main types of polymerization; addition polymerization and condensation polymerization. Addition polymerization creates larger molecules by opening up double bonds on the smaller molecules (monomers). These opened-up bonds react with parts of other monomers (single part) to form dimers (double part). This reaction can repeat to add another molecule to for a trimer (three part). This continues until you obtain the right size molecule and you stop the reaction. Addition polymerixation can occur using a single type of monomer. There are no by products of the reaction except the longer chain molecules (polymers).In condensation polymerization, two monomers of different types are used. They have different types of reactive (or functional) groups on them. A reaction between monomer A and monomer B results in a dimer, plus another small molecule (often water) that is not part of the polymer. To create long polymers the monomers must have reactive groups on both ends or a chain cannot be formed.Polymerization is an all-encompassing term for creating polymers by any method. Condensation Polymerization is a term denoting a specific type of reaction for creating polymers.
What is repeating units in DNA called?
alternating sugar and phosphate molecules.
The repeating unit of cellulose is?
large molecules make up of chains of repeating units are called POLYMERS.
What are repeating subunits of DNA and RNA called?
Nucleotides are repeating subunits that make up DNA.
What is a solid geometeric form that results from a repeating pattern of atoms or molecules?
A crystal.
A repeating pattern of atoms ions of molecules in a mineral is called a?
crystalline structure
Which macromolecules are made repeating small units?
Thrse molecules are called polymers.
What is a regular repeating arrangement of atoms ions or molecules?
A crystal lattice is a regular repeating arrangement of atoms, ions, or molecules in a crystalline solid. This arrangement gives crystals their characteristic structure and properties.
Polymers are large organic molecules that are made up of?
False, polymers are molecules made from repeating units of identical or nearly identical compounds called monomers that are linked together by a series of covalent bonds.
Compute the degree of polymerization of polystyrene?
The degree of polymerization of polystyrene is typically in the range of 1000-2000, meaning that a single polymer chain of polystyrene molecule consists of 1000-2000 monomer units (styrene molecules) linked together. It is calculated by dividing the molecular weight of the polymer by the molecular weight of the repeating unit (styrene monomer).
