Vitamin C (l-ascorbic acid) is an excellent free radical scavenger, not only for its capability to
donate reducing equivalents but also for the relative stability of the derived …

Under conditions of abiotic stress several physiological and biochemical processes in plants
can be modified. The production of reactive oxygen species (ROS) is toxic at high …

Throughout evolution, a number of animals including humans have lost the ability to
synthesize ascorbic acid (ascorbate, vitamin C), an essential molecule in the physiology of …

Ammonium is a major inorganic nitrogen source for plants. At low external supplies,
ammonium promotes plant growth, while at high external supplies it causes toxicity …

Oxidative stress is induced by a wide range of environmental factors including UV stress,
pathogen invasion (hypersensitive reaction), herbicide action and oxygen shortage. Oxygen …

Pectin is a family of complex polysaccharides present in all plant primary cell walls. The
complicated structure of the pectic polysaccharides, and the retention by plants of the large …

Humans are unable to synthesise l‐ascorbic acid (L‐AA, ascorbate, vitamin C), and are thus
entirely dependent upon dietary sources to meet needs. In both plant and animal …

Ascorbic acid (vitamin C) is an abundant component of plants. It reaches a concentration of
over 20 m M in chloroplasts and occurs in all cell compartments, including the cell wall. It …

Ascorbic acid (vitamin C) is the most abundant antioxidant in plants. Its biosynthetic pathway
via GDP-D-mannose and L-galactose, which was proposed only recently, is now supported …

Abstract l-Ascorbic acid (Asc) is the most abundant water-soluble antioxidant in plants. It
serves as a cofactor for enzymes involved in photosynthesis, hormone biosynthesis, and the …
