The nutritional equivalence of pantothenate and p-aminobenzoate for the growth of Bacterium linens.
Knowledge concerning the function of paminobenzoate in biological systems has been derived largely by the use of specificcompetitive inhibitors. Thus, the reversal of either sulfanilamide or 2-chloro4-aminobenzoate inhibition by methionine and other amino acids (Lampen et al., 1946; King et al., 1948; Strandskov, 1947; Winkler and DeHaan, 1948), by pteroylglutamic acid (Nimmo-Smith et al., 1948...

The elucidation of the structure of pteroylglutamic acid (PGA) (Lactobacillus casei factor, vitamin B,) has shown that p-aminobenzoic acid (PABA) is a component of the PGA molecule (1). Since earlier work has treated PABA and PGA as distinct growth factors for bacteria (2), it is now necessary to study the relationship in the utilization of these substances by bacteria. It has been shown that m...
متن کاملSeparation of p-Aminobenzoic Acid Derivatives
According to the literature, p-aminobenzoic acid (PAB) is excreted in the urine mostly as the free acid and its N-acetyl derivative; the remaining part is eliminated conjugated with glucuronic acid and as p-aminohippuric acid (PAH) (Ellinger & Hensel, 1914'; Hensel, 1914; Cohen & McGilvery, 1946; Salassa, Bollman & Dry, 1948). There is no agreement concerning the formation of PAH. Thus, Beyer, ...

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...
