Evolution of substrate specificity in the Nucleobase-Ascorbate Transporter (NAT) protein family [PDF]
, 2018 L-ascorbic acid (vitamin C) is an essential metabolite in animals and plants due to its role as an enzyme co-factor and antioxidant activity. In most eukaryotic organisms, L-ascorbate is biosynthesized enzymatically, but in several major groups ...

Stability of ascorbate in urine: relevance to analyses for ascorbate and oxalate.
Clinical Chemistry, 1985 Abstract Ascorbate is unstable in urine at room temperature at pH values ranging from 1 to 12. At pH 7 and above, oxalate is generated in amounts directly proportional to the ascorbate concentration. In 12 different urines, adjusted to pH 12 and incubated for 20 h at room temperature, there was a significant correlation between the ...

Metabolomic profiling identifies biomarkers and metabolic impacts of surgery for colorectal cancer
Frontiers in Surgery, 2022 BackgroundColorectal cancer (CRC) is one of the most common malignant tumors with recurrence and metastasis after surgical resection. This study aimed to identify the physiological changes after surgery and explore metabolites and metabolic pathways with

Intravenous Vitamin C for Cancer Therapy – Identifying the Current Gaps in Our Knowledge
Frontiers in Physiology, 2018 The use of intravenous vitamin C (IVC) for cancer therapy has long been an area of intense controversy. Despite this, high dose IVC has been administered for decades by complementary health care practitioners and physicians, with little evidence base ...

Pyrophosphate levels strongly influence ascorbate and starch content in tomato fruit
Frontiers in Plant Science, 2013 Ascorbate (vitamin C) deficiency leads to low immunity, scurvy, and other human diseases and is therefore a global health problem. Given that plants are major ascorbate sources for humans, biofortification of this vitamin in our foodstuffs is of ...
