a. Tryptophan was a precursor of niacin.

b. The B vitamins were involved in energy metabolism.

c. Niacin was a water-soluble vitamin.

d. Dermatitis was a symptom of niacin deficiency.

e. diet inadequacies could cause disease.

Answer 1

Niacin was involved in groundbreaking nutrition discoveries related to its precursor, its solubility, its deficiency symptoms, and its relationship to diet inadequacies.

Step-by-step explanation:

Niacin, also known as vitamin B3, has been involved in several groundbreaking nutrition discoveries. One such discovery showed that tryptophan, an amino acid, is a precursor of niacin (tryptophan was a precursor of niacin). Another discovery demonstrated that niacin is a water-soluble vitamin (Niacin was a water-soluble vitamin). Additionally, it was found that niacin deficiency can cause dermatitis, a skin inflammation (Dermatitis was a symptom of niacin deficiency), and diet inadequacies can lead to various diseases (diet inadequacies could cause disease).
