      Sesame is an important oil crop due to its high oil, antioxidant, and protein content. Drought stress is a major abiotic stress that affects sesame production as well as the quality of sesame seed. To reveal the adaptive mechanism of sesame in response to water deficient conditions, transcriptomic and metabolomics were applied in drought-tolerant (DT) and drought-susceptible (DS) Cited by: 2.   Analysis of amino acids was performed using an AAA amino acid analyzer (Ingos, Czechia) equipped with an Ionex Ostion LCP cation-exchange column (20 cm long, mm i.d.). Amino acids in μL-aliquots were injected into the column, and separated by stepwise gradient elution at mL/min, using a Li +-citric buffer system Cited by: 9.

    Introduction. All tissues have some capability for synthesis of the non-essential amino acids, amino acid remodeling, and conversion of non-amino acid carbon skeletons into amino acids and other derivatives that contain r, the liver is the major site of nitrogen metabolism in the body. In times of dietary surplus, the potentially toxic nitrogen of amino acids is eliminated via. The amino acid business is a multi-billion dollar enterprise. All twenty amino acids are sold, albeit each in greatly different quantities (Table 1). Amino acids are used as animal feed additives (lysine, methionine, threonine), flavor enhancers (monosodium glutamic, serine, aspartic acid) and as specialty nutrients in the medical field.

    Coenzyme, pyridoxal phosphate (PLP), in metabolism of amino acids and protein. Amino acid metabolism for synthesis of non-essential amino acids (transfers NH2). Converts homocysteine to methionine. Converts tryptophan to niacin. Roles in synthesis of neurotransmitters, white blood cells, and hemoglobin. Breakdown of stored glycogen to glucose.   The Medical Biochemistry Page is a portal for the understanding of biochemical, metabolic, and physiological processes with an emphasis on medical relevance.

Amino acid metabolism in wheat as affected by environmental factors by Margaret Anne Bevens Maxwell Download PDF EPUB FB2

Molecular and biochemical impacts of environmental factors on wheat grain development and protein synthesis After anthesis, environmental conditions primarily affect kernel size and composition. This review summarizes current information on the effects waxy layer at the chalaza impedes input of sugars and amino acids into the grain.

Amino Acid Metabolism, 3 rd Edition covers all aspects of the biochemistry and nutritional biochemistry of the amino acids. Starting with an overview of nitrogen fixation and the incorporation of inorganic nitrogen into amino acids, the book then details other major nitrogenous compounds in micro-organisms, plants and animals.

Many of the other free amino acids were present at higher levels in the sulfate-deprived wheat, but the levels of free glutamine showed increases similar to those observed for asparagine.

Briefly, combined environmental factors led to a decrease in NR activity that was accompanied by a decline in leaf organic N compounds, including Rubisco protein, chl, and amino acids, whereas fructan content was increased in association with the upregulation of a gene encoding sucrose:fructan 6-fructosyltransferase, as in our prior study Author: Rubén Vicente, Anthony M.

Bolger, Rafael Martínez-Carrasco, Pilar Pérez, Elena Gutiérrez, Björn Usad. One is to know what factors affect the amino acid metabolisms, which need the deep and intensive understanding about the amino acid metabolic processes and its regulations in pigs.

Another one is to know how to regulate the amino acid metabolism by nutritional methods according to the above impacting : Qinghua He, Yulong Yin, Yongqing Hou, Guixin Qin, Hui Sun, Jianhong Liu, Bo Liu, Zongkun Zheng.

The first part of the book deals with intermediary metabolism of amino acids. Particularly noted are alanine, aspartic, adenylosuccinic, hydroxyaspartic acids, and asparagine. The book also has discussions on glutamic acid, glutamine, glycine, serine, and sarcosine.

One is to know what factors affect the amino acid metabolisms, which need the deep and intensive understanding about the amino acid metabolic processes and its regulations in pigs. Glutamine, glutamate, aspartate, and asparagine constitute a metabolic network [hereafter termed for simplicity “amide amino acid metabolism” (AAAM) because it contains the two amide amino acids, glutamine and asparagine] that participates in numerous processes ().These include nitrogen assimilation, nitrogen metabolism into the various amino acids and other nitrogenous compounds, Cited by:   Elango R, Ball RO, Pencharz PB () Amino acid requirements in humans: with a special emphasis on the metabolic availability of amino acids.

As shown here, most amino acids are converted to intermediates of the citric acid cycle or to pyruvate, which in turn can serve as precursors for gluconeogenesis; these are the glucogenic amino acids. Those amino acids that yield acetoacetate are called ketogenic, since acetoacetate is one of the ketone bodies (see slide ).

TOPIC 1. FACTORS AFFECTING PROTEIN METABOLISM Protein metabolism of wild ruminants is affected by both biological and environmental factors. Like other mammals ruminants convert the ammonia released from the amino acids that are not used in.

On the other hand, the amino acid content can also be affected by changes in the activities of enzymes involved in amino acid metabolism in rice grains Glutamine synthetase, glutamic oxalo Cited by: 2. The rate of energy production is called the basal metabolic rate and is affected by factors such as sex, race, exercise, diet, age, and diseases such as sepsis or cancer.

Metabolism refers to the whole sum of reactions that occur throughout the body within each cell and that provide the body with energy. Recent years have witnessed the discovery that amino acids (AA) are not only cell signaling molecules but are also regulators of gene expression and the protein phosphorylation cascade.

Additionally, AA are key precursors for syntheses of hormones and low-molecular weight nitrogenous substances with each having enormous biological by: F. Amino acid nitrogen forms ammonia, which is toxic.

The liver is the major site of amino acid metabolism in the body and the major site of urea synthesis. The liver is also the major site of amino acid degradation, and partially oxidizes most amino acids, converting the carbon skeleton to glucose, ketone bodies, or CO2.

Protein metabolism denotes the various biochemical processes responsible for the synthesis of proteins and amino acids (anabolism), and the breakdown of proteins by catabolism.

The steps of protein synthesis include transcription, translation, and post translational modifications. The impact of bZIP1 and bZIP53 on the starvation-induced transcription of key genes in amino acid metabolism and amino acid accumulation is demonstrated in protoplasts and transgenic plants.

The results of loss-of-function approaches indicate that several partially redundant TFs of the C/S1 bZIP network cooperate to regulate plant low energy Cited by: Using Amino Acids to Help Metabolism. Amino acids may help you to lose weight. If any amino acids are missing from in your diet, then your metabolism and all of your body systems will be affected.

The effects of various light intensities and spectral compositions on glutathione and amino acid metabolism were compared in wheat. Increase of light intensity (low—normal—high) was accompanied by a simultaneous increase in the shoot fresh weight, photosynthetic activity and glutathione content.
