Comparative amino acid and fatty acid compositions of edible gums kondagogu (Cochlospermum gossypium) and karaya (Sterculia urens)

A facile synthesis and characterization of Ag, Au and Pt nanoparticles using a natural hydrocolloid gum kondagogu (Cochlospermum gossypium)

“…FT-IR spectroscopic investigation suggests that the carbonyl groups present in amino acids, peptides and proteins have a stronger ability to bind metal and facilitate the formation of a coat over the metal nanoparticles and favor in stabilizing the Ag nanoparticles against agglomeration. This confirms that the proteins present in the GK are involved in the formation of Ag nanoparticles [35]. Similar finding were reported on the biosynthesis of Ag nanoparticles using Fusarium semitectum, Penicillium brevicompactum and Cladosporioides funguses and they confirmed that carbonyl groups from the amino acid residue and peptides of proteins have strong ability to bind Ag nanoparticles [44][45][46][47].…”

“…Stearic acid (C 18:0 ) (37.25%) was the major fatty acids present in the gum. The unsaturated fatty acid detected include, linoleic acid (3.45%) and ␥-linolenic acid (0.54%), oleic acid (0.50%), palmitoleic acid (5.92%) and erucic acid (6.02%) [35].…”

Fabrication, Characterization, and Antibacterial Properties of Electrospun Membrane Composed of Gum Karaya, Polyvinyl Alcohol, and Silver Nanoparticles

“…GK comprises around 60% neutral sugars and 40% acidic sugars and a range of hydroxyl, carbonyl, carboxyl, and acetyl functional groups [36]. Following addition of AgNO 3 , the GK hydroxyl groups are oxidised to carbonyl groups and Ag + cations are reduced to metallic Ag-NPs.…”

Green Synthesis: Nanoparticles and Nanofibres Based on Tree Gums for Environmental Applications

“…Even though gum karaya, also known as Indian tragacanth, and KG are classified in the same group, there are considerable differences in their physical and chemical properties [101,102]. Extensive research has been carried out on KG (Cochlospermum gossypium), a gum extracted from kondagogu tree, which grows in India, including its morphological, physical and chemical, structural, rheological, pharmaceutical emulsifying properties and its toxicological evaluation as a food additive [79,80,[102][103][104][105][106][107]. Furthermore, this gum can also be used as a biosorbent for the removal of toxic metal contaminants from aqueous environments and also as an environmental friendly material for the stabilization and a reducing agent for the synthesis of metal/metal oxide nanoparticles [108][109][110][111][112].…”
