Vitamin C is involved in the physiology of the nervous system, including the support and the structure of the neurons, the processes of differentiation, maturation, and neuronal survival; the synthesis of catecholamine, and the modulation of neurotransmission.

2022年1月17日 · The following article will overview the sources of vitamin C, the appropriate dosing, metabolism, and the consequences of vitamin C toxicity and deficiency, while examining the impact it has normal physiology and its role as a therapeutic in treating certain ailments.

Plasma vitamin C concentrations depend on dietary intake; vitamin C absorption by the gastrointestinal tract; distribution in body fluids and uptake by tissues; irreversible metabolism of vitamin C (utilization); and vitamin C excretion by the kidneys.

Vitamin C (L-ascorbic acid) has been known as an antioxidant for most people. However, its physiological role is much larger and encompasses very different processes ranging from facilitation of iron absorption through involvement in hormones and carnitine synthesis for important roles in epigenetic processes.

2023年5月1日 · Vitamin C is a water-soluble vitamin, antioxidant, and essential co-factor for collagen biosynthesis, carnitine and catecholamine metabolism, and dietary iron absorption. Humans are unable to synthesize vitamin C, so they can only obtain it through dietary intake of fruits and vegetables.

2015年12月23日 · Vitamin C is involved in the physiology of the nervous system, including the support and the structure of the neurons, the processes of differentiation, maturation, and neuronal survival; the synthesis of catecholamine, and the modulation of neurotransmission.

Ascorbic acid (vitamin C) is an important redox cofactor in plant and animal systems. Most animals make sufficient ascorbic acid; however, for those that lack the enzyme necessary for synthesis, ascorbic acid is a true vitamin.

Even though since 1990 over 5000 research studies have appeared, more information is needed regarding the mechanisms of vitamin C metabolism, the dietary requirement for maintaining optimal health, and the causes of deficiencies in disease states (reviewed in [7]).

1996年1月1日 · This chapter focuses on three aspects of Vitamin C—recent studies where a change in the status of vitamin C is associated with a disease state, evidence regarding the proposed mechanism(s) for the observed changes in vitamin C status in disease states, and the effectiveness of vitamin C as a therapeutic or preventative agent.

Vitamin C is required for the biosynthesis of collagen, L-carnitine, and certain neurotransmitters; vitamin C is also involved in protein metabolism [1, 2]. Collagen is an essential component of connective tissue, which plays a vital role in wound healing.
