Ciência Rural, 2005 Encontrado em diversos alimentos, o amido é a mais importante fonte de carboidratos da dieta. Potencialmente digerível pelas enzimas no trato gastrintestinal, é absorvido na forma de glicose no intestino delgado. Apesar disso, quantidade significativa de

Amido resistente em diversas fontes não convencionais de amido
Millenium, 2016 Amido resistente (AR) é aquele que não é digerido no intestino delgado, conduzindo a efeitos benéficos para a saúde, tal como a fibra dietética faz. Procedeu-se à determinação do AR em farinhas e amidos extraídos de duas variedades de castanha (Castanea ...

Synthesis of non-equivalent diamides and amido-esters via Pd-catalysed carbonylation
Nature Synthesis, 2023 Given the widespread use of amides in chemistry and biology, the development of methods for their synthesis remains important. Although the construction of amide bonds has in principle been known since Wöhler’s urea synthesis, the direct and atom ...

An Isolable Mononuclear Palladium(I) Amido Complex.
Journal of the American Chemical Society, 2021 Mononuclear Pd(I) species are putative intermediates in Pd-catalyzed reactions, but our knowledge about them is limited due to difficulties in accessing them.

Bis(amido)diazadiarsetidinide and Amido(imino)arsenide Complexes of Divalent Metals [PDF]
European Journal of Inorganic Chemistry, 2021 AbstractThe Mg and Ca complexes of the tert‐butyl substituted bis(amido)diazadiarsetidinides [{(tBuNAs)2(tBuN)2}M(thf)2] (M=Mg (1), Ca (6)) were prepared by addition of nBu‐secBuMg or [{(p‐tBu)(C6H4)CH2}2Ca] to [(tBuNAs)2(tBuNH)2] (Ia). Upon evaporation of coordinating THF, 1 is selectively converted to the amido(imino)arsenide complex [Mg{As(NtBu)2}2]

Journal of Plant Nutrition and Soil Science, EarlyView., 2023 Abstract Background Plant responses to deficiencies of the micronutrient boron are diverse and go beyond the well‐characterized function of boron in cell wall crosslinking. To explain these phenotypic discrepancies, hypotheses about interactions of boron with various phytohormones have been proposed, particularly auxin.

Controlled partial transfer hydrogenation of quinolines by cobalt-amido cooperative catalysis
Nature Communications, 2020 Catalytic hydrogenation or transfer hydrogenation of quinolines was thought to be a direct strategy to access dihydroquinolines. However, the challenge is to control the chemoselectivity and regioselectivity.

Acyclic Amido‐Containing Silanechalcogenones
European Journal of Inorganic Chemistry, 2015 AbstractInvited for the cover of this issue is the group of Cheuk‐Wai So at the Nanyang Technological University, Singapore. The cover image shows the isolation of the first stable four‐coordinate silanechalcogenones comprising an acyclic amido substituent by a straightforward oxidation of the amidinato silicon(II) bis(trimethylsilyl)amide with ...

Plant and Cell Physiology, 2019 Auxin is the first discovered plant hormone and is essential for many aspects of plant growth and development. Indole-3-acetic acid (IAA) is the main auxin and plays pivotal roles in intercellular communication through polar auxin transport. Phenylacetic
