Antioxidants scavenge free radicals and other reactive oxygen species (ROS) by interrupting their mechanism of oxidation. Since free radicals cause neurological illnesses, cancer, heart disease, diabetes, atherosclerosis, and lipid and DNA damage, inhibiting their formation has recently been the subject of several medical investigations. Present studies described the determination of total phenolic content and DPPH activity of a large number of commonly used plant and vegetable extracts utilizing Folin-Ciocalte and Soler-Rivas procedures. This study aims to conduct a biochemical analysis of the therapeutic effects of okra, tamarind, and other phenolic compounds. The comparative data provided in this work for antioxidant and polyphenolic substances is expected to be highly valuable for readers who are interested in this subject.","PeriodicalId":8544,"journal":{"name":"Asian Journal of Organic & Medicinal Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139441682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The characteristics of biosynthesized FeNPs were studied by using UV-visible absorption spectroscopy (UV-vis), transmission electron microscopy (TEM), particle size analyzer (PSA) and Fourier transform infrared spectroscopy (FTIR). The typical absorption peak was found to lie within 650-700 nm due to the excitation of surface plasmon vibration in FeNPs.

The visual pigments in both types of photoreceptor cells contain the common chromophore, 11-cis-retinal, linked through a Schiff base linkage to the opsin protein, a member of G-protein coupled receptor (GPCR) family, composed of 7- transmembrane helices (a 7TM receptor). Rhodopsin is the visual pigment present in the rod cells while three distinct types of visual pigments known as photopsins (red cones, green cones and blue cones absorbing red, blue and green parts of the visible spectrum respectively) are present in the cone cells. Absorption of light by the visual pigment causes the photoexcitation followed by photoisomerization, 11-cis-retinal (Z) to all-trans-retinal (E) with a high quantum yield through a number of reactive intermediates characterized by low temperature and picosecond (ps) time resolved spectroscopies coupled with femtosecond spectroscopy. This photoisomerization leads to a change in the conformation of opsin GPCR and a signal transduction cascade by activating transducin, a heterotrimeric G-protein, to breakdown the cGMP to close the cGMP-gated cation channels resulting in hyperpolarization of the photoreceptor cell. This action potential creates a nerve signal that is transmitted to the brain to produce the sense of vision. The photoisomerized pigment undergoes rapidly hydrolysis to produce the opsin protein and all trans-retinal, which can be reconverted enzymatically to 11-cis-retinal for recharging opsin to generate the active visual pigment to maintain the vision cycle (Wald cycle). This brief review highlights the state of our understanding of the biology behind the art of vision in humans and other organisms.","PeriodicalId":8544,"journal":{"name":"Asian Journal of Organic & Medicinal Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91528929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
