What do water-soluble vitamins B and C primarily do?

Water-soluble vitamins, specifically the B vitamins and vitamin C, play vital roles in cellular functions, which includes the protection of the inside of the cell. They are involved in numerous biochemical pathways that affect metabolism, immune function, and antioxidant activity.

Vitamin C, for instance, is known for its role as an antioxidant, helping to protect cells from oxidative stress by neutralizing free radicals. This cellular protection is crucial in maintaining overall health and preventing cellular damage that can lead to various diseases.

The B vitamins, such as B6, B12, niacin, and riboflavin, are essential for energy metabolism as they are involved in converting food into energy. They also support the nervous system and are involved in the synthesis of neurotransmitters. However, while they contribute to energy production, their primary function ties back to supporting cellular health and function.

Therefore, the characterization of water-soluble vitamins B and C as protectors of cellular integrity aligns with their important biochemical roles.
