Recent investigations have shown that distillers’ dried solubles contain a factor or factors which are necessary for the growth of chicks (1) and rats (2). This factor is distinct from vitamin A, vitamin D, thiamine, riboflavin, inositol, nicotinic acid, pantothenic acid, p-aminobenzoic acid, choline, pyridoxine, biotin, folic acid, or 2-methylnaphthoquinone. A procedure has been developed for ...

Animals. The 108 rats used in these experiments were of the Lister Institute blackand-white stock maintained at Queen Elizabeth College. They were weaned at 23 days and taken for experiment either at weaning, weighing 4-50 g in series C, and C,, or 7 days after weaning, weighing 55-80 g in series C15. In the first series, C,, the animals were deprived of pantothenic acid for 2 weeks and then do...

Reduced skeletal muscle free coenzyme A (CoASH) availability may decrease the contribution of fat oxidation to ATP production during high-intensity, submaximal exercise or, alternatively, limit pyruvate dehydrogenase complex (PDC) flux and thereby carbohydrate oxidation. Here we attempted to increase the muscle CoASH pool in humans, via pantothenic acid and cysteine feeding, in order to elucida...

Lean red meats are: • An excellent source of high biological value protein, vitamin B12, niacin, vitamin B6, iron, zinc and phosphorus • A source of long-chain omega-3 polyunsaturated fats, riboflavin, pantothenic acid, selenium and possibly also vitamin D • Mostly low in fat and sodium • Sources of a range of endogenous antioxidants and other bioactive substances including taurine, carnitine, ...

Mycobacillin synthetase lacks aspartic acid racemase, alanine racemase and glutamic acid racemase activities. The enzyme also does not respond to ATP-[32P]Pi exchange, nor does it catalyse the antibiotic synthesis in presence of amino acids of configuration opposite to that present in the molecule. Preincubation with optical isomers of opposite configuration inhibited the ATP-[32P]Pi exchange r...
