ASCn
ASCn refers to a family of genes that encode for enzymes involved in the biosynthesis of ascorbic acid, also known as vitamin C. In humans, the ASCn gene family is not functional, meaning humans cannot synthesize their own vitamin C and must obtain it from their diet. This is in contrast to many other animals, such as rodents and most other mammals, which possess functional ASCn genes and can produce vitamin C internally.
The functional genes within the ASCn family typically encode for enzymes that catalyze specific steps in the
