Sulfated Polysaccharides
In the post-genomic era, science is still challenged to explain the biosynthesis of complex polysaccharides and glycoconjugates. Unlike nucleic acids and proteins, the information needed for their biosynthesis is not clearly contained to this day within the genome of the various organisms. This means that no biosynthetic code has been revealed yet. As a result, there will be millions of structurally distinct, functional chemical species at the end of their biosynthesis. This book offers an up-to-date view on sulfated polysaccharide structure and function state of the art in different life kingdoms: bacteria, protista, plantae, fungi and animalia. The structure, activities and current thinking on the interplay between these two vital features (as well as ways to study them) are reviewed in the present book. The growing economical interest in sulfated polysaccharides due to their potential biotechnological use in different areas, such as pharmaceutical and food industries, are also commented on. The information within the chapters adds to other prior available literature; the intention of the authors was to extend and further develop the discussions related to glycobiology.
Caracterizacao de uma fucana da alga Spatoglossum schroederi e analise de suas atividades anti-adesiva, antimigratoria, antiproliferativa e antitrombotica
Fucana e uma denominacao utilizada para polissacarideos sulfatados, lineares ou nao, que tem como caracteristica estrutural mais marcante a presenca de L-fucose sulfatada. A alga Spatoglossum schroederi produz tres fucanas, denominadas de fucanas A, B e C.A Fuc B, com massa molecular de 21,5 kDa, constituida de fucose: xilose: galactose: sulfato (1: 0,5: 2: 2) e tracos de acido uronico, foi extraida da alga por hidrolise enzimatica e purificada por precipitacao diferencial com acetona e cromatografias de troca ionica e gel filtracao. As analise quimicas, estudos de metilacao e espectroscopia de RMN de 113 e 213, indicaram as principais caracteristicas estruturais da Fuc B. Ela e formada por ...
Amazon Fruits: An Ethnobotanical Journey
This is the first comprehensive listing of Amazon fruits from an ethnobotanical perspective. This detailed book covers 50 botanical families, 207 species, in the Amazon including how the people of each region use them. It is lavishly illustrated with high-quality photographs taken by the author, an extensive list of references, and Dr. Smith’s latest, meticulous research. This book should be a foundational work for scholars working in the plant sciences, researchers in ethnobotanical studies, and general interest scholars seeking more detailed information on the latest research by a leading scientist in the Amazon.

Comprehensive Organic Chemistry Experiments for the Laboratory Classroom
This expansive and practical textbook contains organic chemistry experiments for teaching in the laboratory at the undergraduate level covering a range of functional group transformations and key organic reactions.The editorial team have collected contributions from around the world and standardized them for publication. Each experiment will explore a modern chemistry scenario, such as: sustainable chemistry; application in the pharmaceutical industry; catalysis and material sciences, to name a few. All the experiments will be complemented with a set of questions to challenge the students and a section for the instructors, concerning the results obtained and advice on getting the best outcome from the experiment. A section covering practical aspects with tips and advice for the instructors, together with the results obtained in the laboratory by students, has been compiled for each experiment. Targeted at professors and lecturers in chemistry, this useful text will provide up to date experiments putting the science into context for the students.
Relações Eletrônicas de Consumo
O livro analisa a interação do consumidor com as novas tecnologias, relação essa assimétrica e marcada pelo agravamento de sua vulnerabilidade, exigindo respostas rápidas e modelos regulatórios eficazes, seja na rediscussão dos limites éticos necessários nessa interação muitas vezes forçada e determinista da inteligência artificial, seja no aspecto do controle e responsabilidade das plataformas eletrônicas na economia de dados pessoais em crescente expansão. Propõe-se, também, a ressignificar o papel do Estado como agente regulatório responsável e respeitado pelas Big Techs, assim como sugere um novo empoderamento do consumidor a partir de um modelo de identitário que me...
CIDADE DE TIROS
Conheci o jornalista Ivan Mendonça de Lima em maio de 2021. Em poucos minutos de conversa após um cafezinho na cantina da prefeitura, "xará" pra cá, "xará" pra lá, ele me falou de sua trajetória como jornalista em Goiás e também de seu novo livro. Ao contrário do primeiro, O Espião do Morro, de grande conteúdo político, desta vez a ideia é contar os laços e embaraços familiares. Os antepassados dele, a maioria de sobrenome Mendonça, Rabelo, Lima, Nunes, Oliveira, Gontijo e Bomtempo, contribuíram e muito para o povoamento da cidade de Tiros. Lembrei que meu avô também tem Nunes e Gontijo na certidão de nascimento e a resposta dele saiu na ponta da língua: "Se brincar, so...
