The metabolism of pantothenic acid.

Effect of in ovo Injection of Nicotonic Acid, Pantothenic Acid or Folic Acid on Immune System and Growth of Broiler Chickens

BACKGROUND: In ovo injection of nutrients as an early feeding method in birds directly supplies the nu- trients to the developing embryo. OBJECTIVES: This study was designed to evaluate the effects of in ovo injection of nicotonic acid, panto- thenic acid and folic acid on the performance and immune system of broilers. METHODS: </st...

Cholesterol metabolism in pantothenic acid deficiency.

The metabolism in vitro of cardiac muscle in pantothenic acid deficiency.

An important r81e for pantothenic acid in carbohydrate metabolism was suggested by studies in which pantothenic acid-deficient bacteria (1, 2) and liver (3) were observed to utilize pyruvate at rates much less than normal. The subsequent discovery of Lipmann and his colleagues that the coenzyme of acetylation (coenzyme A) (4) contained pantothenic acid (5) provided a stimulus for the reinvestig...

Effects of excess pantothenic acid administration on the other water-soluble vitamin metabolisms in rats.

To acquire the data concerning the tolerable upper intake level which prevents health problems from an excessive intake of pantothenic acid, an animal experiment was done. Rats of the Wistar strain (male, 3 wk old) were fed on a diet which contains 0%, 0.0016% (control group), 1%, or 3% calcium pantothenate for 29 d. The amount of weight increase, the food intake, and the organ weights were mea...

Different variations of tissue B-group vitamin concentrations in short- and long-term starved rats.

Prolonged starvation changes energy metabolism; therefore, the metabolic response to starvation is divided into three phases according to changes in glucose, lipid and protein utilisation. B-group vitamins are involved in energy metabolism via metabolism of carbohydrates, fatty acids and amino acids. To determine how changes in energy metabolism alter B-group vitamin concentrations during starv...

B-vitamin Nutrition in Dairy Cows

The B-vitamins include thiamin (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), the B6 complex (pyridoxal, pyridoxamine, pyridoxine), biotin (B8 or Vitamin H), folic acid (B9), and B12. Each of the B-vitamins plays a key role as either an enzymatic cofactor or metabolic constituent in many facets of intermediary metabolism. For example, about half of the propionate that reaches the ru...
