The fat-soluble vitamins all have hormone-like activity.
Answer the following statement true (T) or false (F)
False
Only the fat-soluble vitamin D has hormone-like activity.
Because a dietary source is not required if synthesis is adequate to meet needs, the vitamin is more correctly classified as a "conditional" vitamin, or prohormone (a precursor of an active hormone). In the absence of UV-light exposure, an adequate dietary intake of vitamin D is essential to prevent the deficiency diseases rickets and osteomalacia and to provide for cellular needs.
