There are 4 major macromolecules in the cells. What is the monomer of proteins, and what is the basic structure and the covalent bond between them? a) Ammonia is used by many bacteria as a source of the element __. b). Bacteria use the element listed in a, in order to make...
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 ...
Soil enzymes are one type of the most important biological components of the soil ecosystem. They play an important role in organic matter decom- position and nutrient cycling12. For instance, the hydroxylases (e.g. urease and sucrase etc.) can hydrolyze the macromolecules, such as proteins ...
Agar is used in electrophoresis applied to the separation of macromolecules, such as nucleic acids or polypeptides, using the principle of electrophoretic mobility depending on molecular mass, size and electrostatic charge. Nucleic acid fragments can be separated in an agarose gel matrix by chain lengt...
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 ...
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...
S1). In addition, to rule out the CB particles in the blood from the interference of biological macromolecules, we doped the CB particles with Au for more pronounced tracking in biological media. The Au@CB particles showed the same morphology and size as the origin CB particles (Fig. 3c-d...
In addition to the incorporation of frequently used bioactive macromolecules and nanomolecules, burgeoning research has found that multiple physiological cues, including mechanics, electricity, and magnetism, represent fresh prospects for bone regeneration by influencing bone-related cell behaviors and cell ...
We first assessed the feasibility of engineering callose deposition into secondary cell walls using the Arabidopsis thaliana model. We transformed Arabidopsis plants with the cals3m construct using three specific secondary cell wall promoters (pAtIRX8, pAtIRX3, pZeZCP4 (refs. 25,26,27,28)) and de...
