Abstract:

AbstractThis short review describes the assistance of click chemistry in the chemical modification of glycosaminoglycans. Through an alkyne-azide 1,3-dipolar cycloaddition reaction, the chemically and physiologically stable triazole unit connects glycosaminoglycans with other labelled or attached functionalities. The synthesized glycosaminoglycan (GAG) conjugates act as drug carriers, forming hydrogels or nanohydrogels for localized drug delivery or injectable GAGs and so on. These are used in research on antithrombotic agents, protein binding, and hepatocyte growth factors, as well as in mech

Abstract:

The isocyano group is the structurally most compact bioorthogonal group known. It reacts with tetrazines under physiological conditions and has great potential for widespread use in the biosciences.

Protecting group chemistry based on the reaction of isonitriles and tetrazines that allows releasing payloads is a particular focus of the article. We further discuss the atypical steric attractions that take place in the transition state of the reaction between isonitriles and tetrazines, wh

Abstract:

Chemistry is a science fundamentally characterized by the ability of making its own study objects. Chemistry's unique sign language and representations of structural formulas are highly predictive tools. These aspects, together with the richness of qualitative models, make chemistry highly attractive for philosophical studies. However, philosophy of chemistry is, within the philosophy of science, a still relatively young discipline.

Green chemistry can also be referred to as sustainable chemistry and it is the design of chemical products and processes aimed at less or less the use of hazardous substances. It's about lessening the destructive consequences on the environment and the earth's sustainability (Wale et al., 2023; Mane et al., 2023). This accommodates many principles that outline how to design safer chemical reactions as well as technology and the use of green chemicals (De, 2023; Rathi et al., 2023). Such principles include the elimination or reduction of generation, using renewable raw materials, and the produc

Abstract:

This study aim to determine why high secondary and higher secondary school students are losing their interest in Chemistry. This comparative study polled 450 secondary and higher secondary school students from a private institute of Karachi East. Descriptive analysis was done Using SPSS, result showed that secondary school (grade 10) and higher secondary school (grade 11) students are less interested in chemistry but grade 12 students acted inconsistently. Most students of grade 12 were delighted with grade 11 chemistry's numerical-based themes, while others struggled with equations and IUPAC

Abstract:

Concerns persist regarding high school students' chemistry learning. Learning chemistry is challenging because of chemistry's innate complexity and the need for students to construct associations between different, yet related representations of matter and its changes. Students should be taught to reason about and consider chemical phenomena using ‘triplet’ representations. A meta-language to discuss chemistry learning with students regarding these representations and their use is therefore necessary. This paper reports on a classroom intervention in which the teacher used the term ‘triangulat
