provitamin

A provitamin is a substance that may be converted within the body to a vitamin.

The pulp is a good source of β-carotene and provitamin A.

Provitamin A carotenoids are also found in dark red, green, and yellow vegetables.

Researchers list the following factors that determine the provitamin A activity of carotenoids:

Vitamin D metabolism is complex because the provitamin can be formed in the skin by ultraviolet irradiation or obtained from the diet.

The very high proportion of beta-carotene (provitamin A) makes the kaki fruit nutritionally valuable.

It is hoped that the new variety will provide sufficient provitamin A to supplement the diet of people at risk of vitamin A deficiency.

Panthenol (Provitamin B5): benefits hair and skin.

It is commonly found as its alcohol analog, the provitamin panthenol, and as calcium pantothenate.

Red chilies contain large amounts of vitamin C and small amounts of carotene (provitamin A).

Kiwifruit contains carotenoids, such as provitamin A beta-carotene, lutein and zeaxanthin.

Typical of orange-colored plant foods, gac fruit contains carotenoids such as beta-carotene (provitamin A).

Crude palm oil, however, is the richest source of carotenoids in nature in terms of retinol (provitamin A) equivalent.

Papaya fruit is a source of nutrients such as provitamin A carotenoids, vitamin C, folate and dietary fiber.

The term "provitamin" is used when it is desirable to label a substance with little or no vitamin activity, but which can be converted to an active form by normal metabolic processes.

For example, Provitamin B5 is a name for Panthenol, which may be converted in the body to Pantothenic Acid (Vitamin B5).

Plant carotenoids are the primary dietary source of provitamin A worldwide, with β-carotene as the most well-known provitamin A carotenoid.

Panthenol is the alcohol analog of pantothenic acid (vitamin B), and is thus a provitamin of B. In organisms it is quickly oxidized to pantothenate.
