Biosynthesis of trigonelline.
Trigonelline, N-methyl nicotinic acid, was first noted in the seeds of Trigonella joenum-graecum (the fenugreek) (1) and has since been found in the seeds and tubers of many species (2,3) as well as in leaves of one species of pea (4). Although one may assume that trigonelline arises metabolically from nicotinic acid, definitive evidence has been lacking. In the course of several attempts to de...
متن کاملEstimation of underwater noise – a simplified method
A set of procedures has been developed to allow preliminary estimates to be made of underwater noise and its effects on marine species. They do not require detailed acoustic survey data, either of the site or of the proposed plant. However, they still facilitate the comparison of different project proposals to assist in the optimisation of equipment layout and routing. Noise may be due to speci...
متن کاملMetabolism of trigonelline.
During the germination of seeds and the early growth of plants, trigonelline (N-methylnicotinic acid) disappears and pyridine nucleotides appear in the plant tissue (1, 2). Hence, it has been surmised, albeit without direct evidence, that the trigonelline of the seeds is a precursor of pyridine nucleotides in seedling plants. In an earlier study from this laboratory (3), it was shown that prepa...
متن کاملa Simplified Model of Distributed Parameter Systems
A generalized simplified model for describing the dynamic behavior of distributed parameter systems is proposed. The various specific characteristics of gain and phase angle of distributed parameter systems are investigated from frequency response formulation and complex plane representation of the proposed simplified model. The complex plane investigation renders some important inequality cons...
متن کاملA Simplified Estimation of Lactate in Normal Human Blood
We have been accustomed to estimate the lactate in blood by hemolysis in water, removal of the proteins by the method of Folin and Wu (4), treatment of the filtrate with CuSO4 and Ca(OH)2 according to Van Slyke (ll), and estimation of the lactate in the centrifugate by a modification of the aeration method of Friedemann, Cotonio, and Shaffer (6). There have been suggestions that some of the pre...
