Evidently, the egg receives from the maternal body a vast array of amino acids ready made, and the subsequent embryogenetic elaboration of structurally and metabolically specific proteins results from specific integrations and regroupings of these units rather than from their neo-formation.
One can summarize that the incorporation of 15N' into the egg shows the same development as that of the labelled amino acids of the wheat protein and that 15% of the lysine-15N' could be detected in the 16 other amino acids.
If the amino acid composition of the different egg proteins is considered constant, then an increase in an amino acid in the egg may mean that the protein content of the egg has increased or that the proportions of the various egg proteins have changed.
Relative rates of 13C recovery in the egg protein were lowest for hens fed the uniformly 13C labeled amino acid mixture, presumably because of the high proportion of nonessential amino acids.
The examined eggs showed a different percentage of essential and non-essential amino acids and antioxidant amino acids, suggesting a potential for enriching the nutritional values and prolonging the shelf life of the eggs by various nutritional strategic ways to enhance the antioxidant amino acids and the essential amino acid profile in eggs.
Arginine, histidine, lysine, methionine, tyrosine and threonine decreased with egg embryogenesis, suggesting that these are the major free amino acids utilized as the egg develops.
Egg formation per se would not be expected to benefit from non-protein nitrogen as the ratio of essential: non-essential amino acids . . .
Egg production was optimal when limiting amino acids were supplemented, as was indicated from the better performance of hens fed the 13% protein diet.
Differences in the amount of an amino acid in whole eggs might result from differences in (1) the amount of protein per egg, (2) the proportions of the constituent amino acids in the egg proteins, or (3) the relative amounts of the different proteins in the egg.
However, the birds/ response in terms of reduced egg numbers and growth or change in egg composition, suggest that our estimates of amino acid supply are incorrect under these dietary regimes.

The period required to condition Siganid breeders before breeding is at least?
5 answers
The period required to condition Siganid breeders before breeding varies depending on the specific stage of reproduction. For instance, in the case of Siganus guttatus larvae, it is crucial to initiate feeding at the age of 2 days after hatching (DAH) for optimal development. On the other hand, for Siganus luridus, a Lessepsian migrant, individuals were found to be reproductively active upon early settlement in a new area, indicating readiness for breeding. While specific conditioning periods for Siganid breeders are not explicitly mentioned in the provided contexts, it is evident that ensuring proper development and reproductive activity through appropriate feeding and environmental conditions are essential aspects of preparing Siganid breeders for successful breeding. Further research may provide more detailed insights into the ideal conditioning period for Siganid breeders.
Effect of low protein diet on normal individual?
4 answers
Low protein diets have varying effects on individuals. Research shows that protein-free and very low protein diets can lead to decreased energy intake and increased energy expenditure, while moderately low protein diets may increase energy intake without altering expenditure. These diets can impact energy balance through mechanisms like enhanced serotonergic and β-adrenergic signaling, affecting thermogenic markers in tissues. Additionally, low protein diets have been linked to changes in body weight, fat mass, and lean mass, with different levels of protein restriction producing divergent outcomes. Furthermore, studies suggest that controlling proteinuria through reduced dietary protein intake can slow renal damage progression and improve outcomes in kidney patients. Overall, the effects of low protein diets on normal individuals can vary based on the specific protein levels and individual responses.
What is meant by antinutrients in calcium absorption?
5 answers
Antinutrients are naturally occurring compounds in food that hinder the absorption of essential nutrients like calcium. They are present in various plant-based foods and can have both negative and positive effects on health depending on their concentration and interactions with other dietary components. Examples of antinutrients that affect calcium absorption include phytates, tannins, oxalates, and saponins. These compounds bind to calcium and inhibit its absorption, leading to potential mineral deficiencies and micronutrient malnutrition in individuals. However, some antinutrients like phytate, lectins, tannins, saponins, amylase inhibitors, and protease inhibitors may also have health benefits at low concentrations, such as reducing blood glucose levels and cholesterol responses. Various processing techniques like soaking, germination, and cooking can help reduce the levels of antinutrients in foods, thereby improving calcium bioavailability.

What is the molecular mechanism behind lysozyme's ability to induce cell lysis?
5 answers
Lysozyme induces cell lysis through its ability to cleave the β-(1,4)-glycosidic bonds in peptidoglycan, a key component of bacterial cell walls. This hydrolysis action compromises the structural integrity of the cell wall, leading to bacterial lysis. Additionally, conventional type lysozymes possess high cationic properties, enabling them to kill certain bacteria independently of peptidoglycan hydrolysis. Research has shown that the presence of specific combinations of charged amino acids, such as glutamate, histidine, and arginine, can significantly enhance lysozyme's bacteriolytic activity, especially in low ionic strength environments. Furthermore, studies on mycobacteriophages have highlighted the importance of an intact lysozyme-like catalytic domain for efficient cell lysis, emphasizing the crucial role of this domain in the molecular mechanism of lysozyme-induced lysis.
Effect of short term low protein diet on normal individual?
4 answers
A short-term low-protein diet has been shown to impact various aspects of health in different populations. Studies have demonstrated that in normotensive, normoalbuminuric, insulin-dependent diabetes mellitus patients, a 7-day low-protein diet led to a reduction in glomerular filtration rate (GFR) without affecting urinary albumin excretion. On the other hand, in maintenance hemodialysis patients, short-term restriction of dietary protein intake supplemented with keto acids was effective in managing hyperphosphatemia. Additionally, research on dietary protein restriction in healthy individuals has shown that acute meal feeding during protein restriction affects essential amino acids like leucine, methionine, and threonine, potentially limiting their availability. These findings suggest that the effects of a short-term low-protein diet can vary depending on the individual's health status and specific dietary interventions.

Novel techniques like high hydrostatic pressure, pulsed electric fields, and ultraviolet light can modify the structure of egg proteins, potentially improving their functionality for specific treatment conditions and product forms. These nonthermal methods offer promising ways to enhance enzymatic hydrolysis, solubility, emulsification, foaming, gelatinization, and digestion properties of egg proteins while reducing allergenicity.
What is the average macronutrient intake for swimmers?
5 answers
The average macronutrient intake for swimmers varies slightly across different studies. In a study of Sri Lankan national pool swimmers, it was found that approximately 77% of energy was derived from carbohydrates, 9% from proteins, and 14% from fats. Another study on teenage swimming athletes reported protein consumption of around 108.4g in males and 85.1g in females, with energy intake ranging from 2125.9 to 2394.8 kcal. High-performance swimmers in a different study had a daily protein intake of 2.2g/kg/day for men and low fat intake of 1.1g/kg/day for women, with inadequate carbohydrate intake before and after training sessions. Overall, swimmers are recommended to consume 6-10-12 g/kg/d of carbohydrates, 2 g/kg/d of protein, and ensure fat intake surpasses 20-25% of the daily intake to optimize performance.
