1. Obtenção de concentrados proteicos de amaranto (Amaranthus sp) por diferentes processos e avaliação de seus efeitos em algumas propriedades / Obtained of amaranth protein concentrates (Amaranthus sp) by different process and evaluation of its effects on some properties
Um caminho importante para a utilização dos grãos de amaranto é a produção de isolados ou concentrados protéicos, tornando-se um ingrediente potencial para uso na formulação de alimentos. Diferentes processos para obtenção de concentrados protéicos e avaliação de seus efeitos nas propriedades funcionais foram estudados neste trabalho. O trabalh

2. Rheological and thermal behavior of amaranth starch-sodium caseinate systems : effect of sugar addition and acidification time / Comportamento reologico e termico de sistemas amido de amaranto-caseinato de sodio : efeito da adição de açucar e tempo de acidificação
The starches are frequently added to the foods owed their properties and water retention, as colloidal emulsion-estabilizing agents. The amaranth is a low cost culture, and his starch, a new ingredient with potential industrial use. The caseinato of sodium is a salt derived of the casein thoroughly used as emulsion in foods. The study proteins and polysaccha

3. Bioatividade do grão de amaranto : avaliação in vitro da atividade ligante de acidos biliares e inibidora da enzima conversora de angiotensina. / Bioactivity of the amaranth grain : in vitro assessment of the binding bile acids and inihibitory activity of the angiotensin converting enzyme.
Amaranth has been highlighted as an excellent alternative or complementary source of food protein due to its balanced amino acid composition. The culture of amaranth has been introduced into Brazil on account of its optimum nutritional (high protein content and better biological quality than that of cereal protein) and functional quality, apart from its agri

4. Regulation of C4 Gene Expression in Developing Amaranth Leaves.
Immunofluorescence microscopy and in situ hybridization were used to examine the expression of genes encoding C4 photosynthetic enzymes during early leaf development in the C4 dicotyledonous grain plant amaranth. During early developmental stages, the chloroplast-encoded large subunit and nuclear-encoded small subunit genes of ribulose-1,5-bisphosphate carbo

5. Identification of Granule-Bound Starch Synthase in Potato Tubers 1
Starch granules isolated from potato (Solanum tuberosum L.) tubers were extracted with sodium dodecyl sulfate and the extract was analyzed. A major protein with a molecular weight of 60,000 daltons was detected. This protein was purified by preparative sodium dodecyl sulfate-gel electrophoresis and specific antibodies were prepared. The anti-60-kilodalton an

6. C4 Photosynthetic Gene Expression in Light- and Dark-Grown Amaranth Cotyledons.
The patterns of expression for genes encoding several C4 photosynthetic enzymes were examined in light-grown and dark-grown (etiolated) cotyledons of amaranth (Amaranthus hypochondriacus), a dicotyledonous C4 plant. The large subunit and small subunit of ribulose-1,5-bisphosphate carboxylase (RuBPCase), phosphoenolpyruvate carboxylase (PEPCase), and pyruvate

7. Translational regulation of light-induced ribulose 1,5-bisphosphate carboxylase gene expression in amaranth.
The regulation of the genes encoding the large and small subunits of ribulose 1,5-bisphosphate carboxylase was examined in amaranth cotyledons in response to changes in illumination. When dark-grown cotyledons were transferred into light, synthesis of the large- and small-subunit polypeptides was initiated very rapidly, before any increase in the levels of t

8. Light-mediated control of translational initiation of ribulose-1, 5-bisphosphate carboxylase in amaranth cotyledons.
In cotyledons of 6-day-old amaranth seedlings, the large subunit (LSU) and the small subunit (SSU) polypeptides of ribulose-1,5-bisphosphate carboxylase are not synthesized in the absence of light. When dark-grown seedlings were transferred into light, synthesis of both polypeptides was induced within the first 3 to 5 hr of illumination without any significa

9. Coordinate, Organ-Specific and Developmental Regulation of Ribulose 1,5-Bisphosphate Carboxylase Gene Expression in Amaranthus hypochondriacus1
The expression of the genes encoding the large subunit (LSU) and small subunit (SSU) of ribulose 1,5-bisphosphate carboxylase (RuBPCase) was examined in roots, stems, cotyledons, and leaves of amaranth during the development of these tissues. The highest accumulation of LSU and SSU polypeptides occurred in cotyledons and leaves. Their steady state levels wer

10. Carbon Sink-to-Source Transition Is Coordinated with Establishment of Cell-Specific Gene Expression in a C4 Plant.
Plants that use the highly efficient C4 photosynthetic pathway possess two types of specialized leaf cells, the mesophyll and bundle sheath. In mature C4 leaves, the CO2 fixation enzyme ribulose-1,5-bisphosphate carboxylase (RuBPCase) is specifically compartmentalized to the bundle sheath cells. However, in very young leaves of amaranth, a dicotyledonous C4
