Amino Sugar(아미노 설탕)란 무엇입니까?
Amino Sugar 아미노 설탕 - These results indicated that CDs-Kan was shown to retain the good antibacterial activity of Kan as well as its main bactericidal functional groups, namely, the amino sugar and amino cyclic alcohol, We refer to this phenomenon as the "preservation property". [1] GLUT2 is also a low KM transporter of the amino sugar, glucosamine (GlcN), which enters the hexosamine biosynthetic pathway (HBP) and provides substrate for glycosylation reactions. [2] The results showed that in the 0−10 cm soil layer, compared with the NTR0% treatment, concentrations of hydrolysable NH4+-N, amino sugar-N and active-SON and N-acetyl-β- d -glucosaminidase (NAG) activity were significantly increased in the NTR33% treatment. [3] Recent studies have shown that amino sugars, such as N-acetyl glucosamine, are released from the turnover of host macromolecules, such as glycosaminoglycans, glycoproteins, and proteoglycans, inside the parasitophorous vacuole. [4] Microbial mineralization of both SOC and added litter was examined in tandem with potential extracellular enzyme activities, while microbial biomass synthesis and necromass accumulation were analyzed using phospholipid fatty acids and amino sugars coupled with 13 C analysis, respectively. [5] The soil properties, P fractions, amino sugars, and phosphatase activities were determined. [6] 7 μm size-fraction had a higher contribution of non-essential AA and acidic and amino sugars, setting them apart from the 0. [7] Amino acids (AAs) and amino sugars (ASs), compounds ubiquitous to living organisms, can provide information regarding degradation states and bacterial contributions to sedimentary organic matter (SOM). [8] Glycosaminoglycans (GAGs) are linear polysaccharides that consist of alternating disaccharides sequences of uronic acids and/or galactose hexamino sugars most of which are sulfated. [9] Ergosterol and amino sugars were used as markers for faecal microbial biomass, that is the sum of fungi and bacteria. [10] , N-acetylamino sugar (84 μg/ml) and free amino acids (112 μg/ml), were carried out by utilizing shrimp and crab shell powder as principal substrate. [11] Amino sugars are key microbial biomarkers for determining the contribution of microbial residues in soil organic matter (SOM). [12] , aldoses, ketoses, alditols, amino sugars, and uronic acids) in plant-derived polysaccharides. [13] The degradation mechanism involves the extracellular decomposition of HMX and transformation of the degradation products into intracellular purines, amino sugars, and nucleoside sugars that then participate in cell metabolism. [14] Bacterial chitinases recruited multiple accessory domains for the conversion of recalcitrant polysaccharides to simple soluble sugars/amino sugars. [15] The use of amino sugars of this type in the synthesis of natural carbohydrate-containing compounds and their analogues, including aminoglycoside antibiotics, glycosidase inhibitors, substrate analogues and inhibitors of glycan biosynthesis, galectin inhibitors, etc. [16] We analyzed for amino sugars, as a microbial residue biomarker, and adopted stable-isotope-probing technique to trace the assimilation of 15NH4+-N (added in the form of 15 N-labelled ammonium sulphate) into amino sugars with or without organic C sources (glucose and crop residue) in native grassland and converted cropland soils over a 65-day period. [17] Soil is majorly bound with inorganic (NO2−, NO3−, non-exchangeable (mineral-fixed) NH4+, exchangeable NH4+, nitrous oxide (N2O) and dinitrogen gas (N2)) and organic forms (amino acids, amino sugars and nucleic acid bases) of Nitrogen. [18] , amino sugars). [19] eCO2 increased plant growth and, consequently, the total 13C incorporated into the shoots, roots, and SOC compared to aCO2, while N fertilization (100 kg N ha−1) decreased root biomass and rhizodeposits in the soil and microbial pools, including living biomass (phospholipid fatty acids, PLFA) and microbial necromass (amino sugars). [20] RESULTS Characteristic patterns and specific pathways emerged for each phenotypic group: amino sugars for CAD/high-RF; urea cycle for no-CAD/high-RF; glutathione for CAD/low-RF; glycine and serine for no-CAD/low-RF. [21] Here we provide the first batch of regional-scale MNC data based on amino sugars for the Qinghai-Tibet Plateau alpine grasslands. [22] However, significant differences in the metabolome related to fatty acid metabolism, oligosaccharides, amino sugars, amino acids, vitamins and oxidative stress-related metabolites were observed when comparing milk from mothers with control infants of ≤1. [23] The facile reaction of a readily available aminopolyol from the chiral pool, N-methyl-d-glucamine, which avoids the side reactions usually associated to anomers of amino sugars, with epoxide and polyepoxide derivatives, enables the preparation of new non-ionic surfactant-like structures combining hydrophilic and hydrophobic moieties. [24] We report here a reaction that selectively deaminates primary amines and anilines under mild conditions and with remarkable functional group tolerance including a range of pharmaceutical compounds, amino acids, amino sugars, and natural products. [25] The FT-IR peaks revealed the likely presence of various compounds such as glycosides, flavonoids, steroids, saponins, flavonoids, amino sugars, cutin and isothiocyanate. [26] Surface functionalization of silica nanoparticles (SiNPs) with biomolecules, such as amino acids, amino sugars and carbohydrates was performed to produce surface-functionalized silica nanoparticles (f-SiNPs) through physical adsorption on the surface of colloidal SiNPs. [27] At two sites, the alkaline site Hochschwab and the acidic site Rauris, soil samples from three elevation levels and depths were analysed for amino sugars as microbial necromass indices, extracellular enzymes, and phospholipid fatty acids (PLFA) as microbial biomass indices. [28] Lignin-like (64% and 62%) and protein/amino sugars (17% and 18%) species accounted higher proportions of HULIS. [29] Larger bacterial 'necromass' (amino sugars) concentrations in soil under winter warming coincided with a 12% increase in carboxyl-C. [30] We report for the first time that the imidate radical can be efficiently added to glycals to generate glycosyl radicals, based on which a general, toxic-reagent-free synthesis of C-glycosides of 2-deoxy-2-amino sugars has been developed. [31] Significant correlation was found between different N fractions (Total N, Ammoniacal-N, Nitrate-N, Total Hydrolysable-N, Hydrolysable ammoniacal-N, Amino Acid-N, Amino Sugar-N, Unidentified-N, Non-hydrolysable N, Available N) and yield as well as N uptake of maize. [32] Under the concept of shell biorefinery, distinctive protocols have been established to chemically transform chitin as the sole feedstock to amino sugars, amino alcohols, furanic amides, and N-heterocycles. [33] N-Acetyllactosamine (LacNAc) or more specifically β-d-galactopyranosyl-1,4-N-acetyl-d-glucosamine is a unique acyl-amino sugar and a key structural unit in human milk oligosaccharides, an antigen component of many glycoproteins, and an antiviral active component for the development of effective drugs against viruses. [34] Glucosamine (C6H13NO5) is an amino sugar (2-amino-2-deoxy-β-D-glucopyranose) and is a part of the structure of two polysaccharides, chitosan and chitin. [35] By contrast, PSR has a positive effect on the accrual of microbial-derived components (represented by amino sugars and mineral-associated organic matter) but not plant residues likely via affecting dissolved organic matter (DOM) and nitrogen availability in the subsoil (i. [36] When fed with AS's effluent, it consumed at least 72% of the exogenous mDON and notably reduced the amount of protein/amino sugar-like compounds. [37] This study examined the changes in biopolymers (lignin, substituted fatty acids, amino sugars) in 0–10 cm and 10–20 cm soil depth in a temperate forest after five years of aboveground litter addition or removal treatments. [38]이러한 결과는 CDs-Kan이 Kan의 우수한 항균 활성과 주요 살균 작용기, 즉 아미노당 및 아미노 고리 알코올을 유지하는 것으로 나타났습니다. 이 현상을 "보존 특성"이라고 합니다. [1] GLUT2는 또한 헥소사민 생합성 경로(HBP)에 들어가 글리코실화 반응을 위한 기질을 제공하는 아미노당인 글루코사민(GlcN)의 낮은 KM 수송체입니다. [2] 결과는 0-10 cm 토양층에서 NTR0% 처리와 비교하여 가수분해성 NH4+-N, 아미노당-N 및 활성-SON 및 N-아세틸-β-d-글루코사미니다제(NAG) 활성의 농도가 NTR33% 처리에서 유의하게 증가했습니다. [3] 최근 연구에 따르면 N-아세틸 글루코사민
