Macromolecules are large molecules known as polymers that are composed of repeating subunits known as monomers. There are four classes of macromolecules that perform a variety of tasks and functions for the maintenance of cells and biological life....
Macromolecules: A macromolecule is a very large molecule and the fundamental component of these macromolecules is carbon. Macromolecules have covalent bonds. Answer and Explanation:1 The four major macromolecules are carbohydrates, lipids, proteins, and nucleic acids. All four macromolecules are polymer...
In a linear macromolecule the monomeric units are joined covalently into a chain whose length is characterized by the degree of polymerization (the number of repeating units) or by the molecular weight. The aggregate of the macromolecules of a given polymer, as distinct from the molecules of a ...

During senescence, leaf cells experience extensive alterations in gene expression and metabolism, resulting in the decomposition of macromolecules and the reallocation of essential nutrients to newer tissues or reproductive organs3,4. Premature leaf senescence can be induced by unfavorable environmental ...
and targeting factors can be introduced to transport drugs to specific disease sites through the physical and chemical properties of the polymer, such as active or passive targeting [82]. When polymer-based chemotherapy drugs are bound to water-soluble macromolecules, the resulting drug exhibits impro...
2. The mean roll distance 〈D〉 is governed by the material as well as process parameters: The material defines the absorption at the given laser wavelength as well as the orientation of the macromolecules. For a certain wavelength, the number of laser pulses applied is the main process ...
A subset of vacuoles are the organelles known as lysosomes, which contain digestive enzymes (packaged in lysosomes in the Golgi complex) that can break down most biological macromolecules. They act to digest food particles and to degrade damaged cell parts. 液泡的一个亚类是被称为溶酶体的细胞器...
Since the implementation of anti-angiogenesis as a strategy in treating cancer, a long list of chemical synthetic moieties, natural compounds, macromolecules and even treatment modalities have been suggested under this mechanism (Table 1). Table 1. List of FDA-approved anti-angiogenic agents. Anti-...
In view of the fact that a significant fraction of the gut space is occupied by macromolecules, it is important to consider the impact that crowded medium might have on the self-assembly of nanostructures and lipid hydrolysis. The term “macromolecular crowding” was coined to connote the ...
