“…The WG and LA activity are often used to estimate the optimum supplementation level of nutrient components in fish [82,83]. Based on the quadratic regression analysis of WG and LA, the present study illustrated that the optimal levels of dietary GMP for juvenile red sea bream might be 0.48% and 0.45% respectively which is also inline with the most of the growth performance and health parameters of fish under present experimental condition.…”

“…Moreover, this situation caused an increase in the activity of enzymes involved in liver metabolism such as GR, GPX, and GST but did not affect catalase and superoxide dismutase [16]. Contrary to this, in two different in vivo studies, Ctenopharyngodon idella was fed with niacin or nicotinamide and the results of these studies revealed that niacin decreased GR activity [32,33].…”

Glutathione reductase (GR, EC 1.8.1.7) is an antioxidant enzyme and is involved in the reducing reaction of oxidized glutathione. Glutathione and reduced glutathione are very crucial for micro-and macroorganisms because of their barrier function against radicals. Therefore, the aim of this article was to purify GR and evaluate the relationship between purified GR and vitamins. GR was purified from bovine liver using 2',5'-ADP Sepharose 4B column materials. To check the purity of each subunit of the enzyme, SDS-PAGE electrophoresis was performed and each one was 55 kDa. Afterwards, specific activity and purified ratio for the enzyme were calculated as 54 EU/mg × protein and 2700 times, respectively. Vitamins have a regulatory role in organisms and also some, like vitamin B, are coenzymes due to having cofactor effects. In this project, variable concentrations of some water-soluble vitamins, riboflavin, ascorbic acid, nicotinamide, folic acid, and thiamine, were tested. As a result of these kinetic findings, nicotinamide and folic acid increased the activity of glutathione reductase, while thiamine decreased it. Riboflavin and ascorbic acid did not show a stable effect on enzyme activity. Ki and IC 50 constants were found as 50.16 ± 5.63 mM and 21.04 mM, respectively, when Lineweaver-Burk and activity % vs. inhibitor concentration graphs were drawn for thiamine. The results of this article illustrate that the behaviors of vitamins could be complicated and vary from one living organism to other; in other words, they are unpredictable.

“…Calcium required for maintenance was 0.12±0.45 g/kg diet ( Fig 1c ). In study 4, a growth test was done to measure the lysozyme activity in the distal intestine of young grass carp fed graded levels of thiamin [ 16 ]. The 90, 95, and 99% of maximum lysozyme activity in the distal intestine of young grass carp were estimated at 0.71±0.17, 0.84±0.21, and 1.08±0.28 mg/kg of dietary thiamin, respectively ( Fig 1d ).…”

“…Testing the applicability of the derived mathematical model was done in two steps on the basis of the published data obtained from 6 studies [ 11 – 16 ] and simulated data sets generated by the software. At the first step, the function ( Eq 5 ) was used to analyze the data of the nutritional experiments for 5 animal, chick and human, 5 nutrients (protein, calcium, thiamin, tryptophan, and vitamin C), and 6 responses (energy balance, bone quality, nutrient excretion, enzyme activity, weight gain, and intracellular nutrient concentration), summarized in Table 1 and illustrated in Fig 1 .…”

Several mathematical equations have been proposed to modeling nutrient-response curve for animal and human justified on the goodness of fit and/or on the biological mechanism. In this paper, a functional form of a generalized quantitative model based on Rayleigh distribution principle for description of nutrient-response phenomena is derived. The three parameters governing the curve a) has biological interpretation, b) may be used to calculate reliable estimates of nutrient response relationships, and c) provide the basis for deriving relationships between nutrient and physiological responses. The new function was successfully applied to fit the nutritional data obtained from 6 experiments including a wide range of nutrients and responses. An evaluation and comparison were also done based simulated data sets to check the suitability of new model and four-parameter logistic model for describing nutrient responses. This study indicates the usefulness and wide applicability of the new introduced, simple and flexible model when applied as a quantitative approach to characterizing nutrient-response curve. This new mathematical way to describe nutritional-response data, with some useful biological interpretations, has potential to be used as an alternative approach in modeling nutritional responses curve to estimate nutrient efficiency and requirements.
