If proteins are all polymers of amino acids, then how can different proteins have different shapes and take on different functions? What is the large molecule formed when many smaller molecules bond together called? What are small subunits that compose polymers cal...
On the primitive Earth, polymers such as proteins and nucleic acids in aqueous suspension formed the spherical aggregats. These are called Aliposomes Bprimitogens Ccoacervates DprimitosomesSubmit Nucleic acid is a condensation polymer of ASimple sugars BAmino acids CNucleotides DStyreneSubmit Nucleic...
The majority of life on Earth relies on polymers made up of 20 differentamino acids, which have evolved into hundreds of thousands of specialized proteins. These proteins perform various functions such as catalyzing reactions, forming the backbone and muscles, and even generating movement. However, ...
This study demonstrates the involvement of conserved amino acids in the dextransucrase active site (Asp551, Glu589 and Asp622) in the polymerization of dextran, as well as showing that a single active site mediates dextran synthesis by a two-catalytic-site insertion mechanism. Article CAS PubMed...
The heteropolymer consists of N connected beads which can be thought of as representing the α-carbons of various amino acids. The heteropolymer may consist of hydrophobic (b), hydrophilic (l), and neutral (n) beads. Two adjacent beads are connected by a covalent bond of fixed length η....
In this paper there are preliminary results of investigations of initiation of vinyl polymerization by the system aminoalcohol-carbon tetrachloride-copper salt. As aminoalcohol (−)-ephedrine and 2-diethylaminoethanol were used. The copper salt was represented by copper acetate, stearate and chloride...
In recent years, significant progress has been made in the development of polymeric materials, driving rapid expansion in associated industries and a surge
Furthermore, the compati- bility of the components always governs the phase structure of the composites. Recently, we synthesized a series of so-called heterogeneous network polymers by esterifying the r-carboxyl groups of poly(glutamic acid) [PGA] with the hydroxyl groups of poly(oxy- ethylene...
The miscibility leads to the formation of IPN after cross-linking. FT-IR also examined the cross-linking mechanism of genipin with primary amino groups. The degree of cross-linking increased with increase genipin concentration. Swelling results revealed that the IPN hydrogels are pH-sensitive, ...
