背景:

カリウムは,米の収穫量と品質に不可欠です.
穀物タンパク質と食生活の質に対するカリウム投与の遅延の影響は十分に理解されていません.

研究の目的:

異なるカリウム肥料の適用タイミングが米粒のタンパク質代謝,食生活の質,収穫量に与える影響を調査する.
米の生産と品質を向上させるために最適なカリウム管理戦略を決定する.

主な方法:

4つのカリウム肥料管理モードが評価され,基礎肥料とパニクル肥料の適用の比率を変化させました (10:0, 8:2, 6:4, 4:6).
測定対象は,穀物タンパク質,タンパク質分,自由アミノ酸,酵素活性 (GS,GOGAT,GOT,GPT),粉RVAプロファイル,味値,加工/外観品質,収穫量などでした.

主要な成果:

遅延したカリウム (K4) の投与は,主要なタンパク質合成酵素の活性を低下させ,穀物の全体的なタンパク質含有量を減少させた.
粉の性質が改善され,ピーク粘度と分解が増加し,後退が減少しました.
食事の質 (味の価値) と身体の質 (頭米率) が向上し,チョーク味は減少した.
収穫量はK4治療で3.48%大幅に増加しました.

結論:

遅延したカリウム肥料の適用は,タンパク質合成を効果的に減らし,食生活と加工品質を向上させ,米の収穫量を高めます.
基礎肥料とパニクル肥料の適用 (K4) の 4:6 の比率は,米の生産を最適化するための有益な戦略を表しています.

ATP Yield

79.2K

Cellular respiration produces 30 - 32 ATP per glucose molecule. Although most of the ATP results from oxidative phosphorylation and the electron transport chain (ETC), 4 ATP are gained beforehand (2 from glycolysis and 2 from the citric acid cycle).
The ETC is embedded in the inner mitochondrial membrane and is comprised of four main protein complexes and an ATP synthase. NADH and FADH2 pass electrons to these complexes, which pump protons into the intermembrane space. This distribution of...

Reaction Yield

60.6K

The theoretical yield of a reaction is the amount of product estimated to form based on the stoichiometry of the balanced chemical equation. The theoretical yield assumes the complete conversion of the limiting reactant into the desired product. The amount of product that is obtained by performing the reaction is called the actual yield, and it may be less than or (very rarely) equal to the theoretical yield.

Binge Eating Disorders

512

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Protein Folding Quality Check in the RER

5.3K

ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...

Regulation of Sodium and Potassium

2.4K

The regulation of sodium and potassium ion concentrations in the human body is a complex process governed primarily by hormones such as aldosterone, antidiuretic hormone (ADH), and atrial natriuretic peptide (ANP).
Sodium Regulation
Sodium ions make up approximately 90% of extracellular cations, with a normal blood plasma concentration of 136–148 mEq/L. A decrease in blood volume and pressure triggers the release of renin from granular cells in the juxtaglomerular complex (JGC), primarily...

Alterations in Respiration II

1.9K

There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...
