VC is also a cofactor in the conversion of violaxanthin to zeaxanthin, catalyzed by violaxanthin de-epoxidase during the xanthophyll cycle, contributing to the protection of the photosynthetic apparatus from photodamage in excess light conditions.

Hair loss and poor haircoat are reported; vitamin C is important in the disulfide bonding of hair.

finding clues regarding a connection between genetic errors, metabolic pathway malfunction & how it appears directly connected to the reason humans do not make vitamin C like most other plants & animals.

its all interconnected in one single genetic malfunction to a single enzyme reaction.

Vanillyl Alcohol Oxidase (VAO) is a fungal flavoenzyme, particularly found in lignin-degrading ascomycetes, that catalyzes the oxidation of various para-substituted phenols. It belongs to a family of oxidoreductases sharing a conserved FAD-binding domain, with the enzyme itself named for its ability to oxidize vanillyl alcohol to vanillin.

Flavoenzymes
Biocatalytic Applications

Flavoenzymes are colourful oxidoreductases, some flavoenzymes the isoalloxazine ring of the flavin is covalently linked to a His, Cys or Tyr residue of the polypeptide chain, typically contain either a FMN or a FAD cofactor,
