The effect of different concentrations of salicylic acid on physiological parameters in pepper (Capsicum annuum L.) [PDF]

open access: yesفیزیولوژی محیطی گیاهی, 2019
Salicylic acid (SA) is an antioxidant which has been used in recent years to increases the resistance of plants to deal with stresses. In this study 5 weeks after germination, different concentrations (0.1, 0.7, 1.5, 3, 6 and 9 mM) of salicylic acid ...

The impact of cold chain temperature abuses on the quality of frozen strawberries (Fragaria ×ananassa)

open access: yesInternational Journal of Food Studies, 2013
The quality of frozen foods can be negatively affected if improper storage and distribution temperatures are allowed. The objective of this study was to investigate the effect of freeze-thaw cycles, which may occur in the cold chain, on colour (Lab ...

SVCT2 Overexpression and Ascorbic Acid Uptake Increase Cortical Neuron Differentiation, Which Is Dependent on Vitamin C Recycling between Neurons and Astrocytes

open access: yesAntioxidants, 2021
During brain development, sodium–vitamin C transporter (SVCT2) has been detected primarily in radial glial cells in situ, with low-to-absent expression in cerebral cortex neuroblasts.

The physiological role of dehydroascorbic acid [PDF]

open access: yesFEBS Letters, 2002
Dehydroascorbic acid (DHA) is abundant in the human diet and also is generated from vitamin C (ascorbic acid, AA) in the lumen of the gastrointestinal tract. DHA is absorbed from the lumen of the small intestine and reduced to AA, which subsequently circulates in the blood. Utilization of AA as an antioxidant and enzyme cofactor causes its oxidation to

Ascorbic Acid, Ascorbate, and Dehydroascorbic Acid as Green Corrosion Inhibitors: A Computational Investigation

open access: yesCorrosion and Materials Degradation
Ascorbic acid is widely used as an immunity-enhancing and antioxidant supplement for treating influenza and other virus-based illnesses. The lactone ring and the oxygenated groups make this system and derived structures attractive as possible ...

Spectrophotometric determination of ascorbic acid and dehydroascorbic acid

open access: yesClinical Chemistry, 1995
Abstract We present a method for measuring ascorbic acid in methanol/trichloroacetic acid extracts prepared from human plasma after enzymatic oxidation of ascorbic acid to dehydroascorbic acid by ascorbate oxidase. Samples were assayed by spectrophotometrically monitoring the kinetics of the concentration-dependent absorbance changes of ...

Inhibition of Calcium‐Dependent Lipid Droplets Relocation of ACSL4‐PKCβ‐ALOX15 Complex Alleviates Ferroptosis and Acute Pancreatitis

open access: yesAdvanced Science, EarlyView.
This study identifies L‐type calcium channel blockers as novel ferroptosis inhibitors. It reveals that PKCβ, activated in calcium dependent manner, phosphorylates and activates ACSL4 and ALOX15, relocating them to lipid droplets to promote lethal lipid peroxidation and ferroptosis.
