Pyrophosphate-dependent 6-phosphofructokinase, a new glycolytic enzyme in pineapple leaves

Biochemical and Biophysical Research Communications, 1979
Abstract Pineapple leaves contain a pyrophosphate-dependent 6-phosphofructokinase which has been partially purified and characterized. In crude extracts the pyrophosphate-dependent activity is 10 to 20-fold higher than the ATP-dependent activity. The partially purified activity is near 2.5 μmol Fru-1,6- P 2 formed/min/mg protein.

ANALYSIS OF THE EFFECT OF VOLUME FRACTION VARIATION ON TENSILE AND BENDING STRENGTH OF COMPOSITE FIBER COMBINATION OF PINEAPPLE LEAVES AND FIBERGLASS WITH POLYESTER RESIN MATRIX BY COMPRESSION MOLDING METHOD

DINAMIKA : Jurnal Teknik Mesin
Pineapple leaf fiber is a waste that is widely found on the island of Sumatra and its potential utilization has not been maximized. Pineapple leaf fiber has potential as a constituent of natural fiber composites.

PRE- AND POSTHARVEST METABOLISM OF CROWN LEAVES OF PINEAPPLE FRUIT

Acta Horticulturae, 2011
Crown burn on exported pineapple fruit causes serious economical losses. In this study, crown burn occurrence was hypothesized to be related to Crassulacean Acid Metabolism (CAM). However, the functioning of this metabolism in the crown leaves remained unexplored.

ON PARAMETRIC STUDY OF FLUID LEAVES AND FLUID PINEAPPLE

International Journal of Fluid Mechanics Research
Liquid chain is a commonly known phenomenon, and it is found to be formed under free fall or due to impact of liquid on surface. Usually, these liquid chains have rim and lamina, which are explained by instabilities. In this article, we examined a variant of liquid chain and carried a parametric study experimentally. Since this phenomenon is reason for

[New cerebroside from leaves of pineapple].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2008
To study the chemical constituents of the leaves of pineapple.Chromatographic methods were used to isolate compounds from the leaves of pineapple and spectral methods were used to identify the structures of the isolated compounds.Compound 1 was isolated from the leaves of pineapple. It was identified as 1-O-beta-D-glucopyranosyl-(2S, 3R, 4E, 11E)-2-[(2(

REACTION MECHANISM OF PYROPHOSPHATE-DEPENDENT PHOSPHOFRUCTOKINASE FROM PINEAPPLE LEAVES

Journal of Food Biochemistry, 1993
Data obtained from initial velocity, product inhibition and dead-end inhibition patterns indicate that the pyrophosphate-dependent phosphofructokinase from pineapple leaves has a rapid equilibrium random mechanism with E:F6P:MgPPi and E:MgPPi:FBP dead-end complexes. The pH dependence of enzyme-reactant dissociation constants suggests that phosphates of

Chemical analysis and pulping study of pineapple crown leaves

Industrial Crops and Products, 2006
Abstract The potential of the pineapple crown leaves as a pulp source was explored. Preliminary results showed that the semichemical mechanical process yielded a pulp of which handsheets without damage could not be made. However, the alkaline pulping process such as kraft or soda resulted in a pulp of which normal handsheets could be produced.

Metabolic profile and cytotoxicity of non-polar extracts of pineapple leaves and chemometric analysis of different pineapple cultivars

Industrial Crops and Products, 2018
Abstract The use of co-products from the fruit agroindustry as a source of bioactive molecules presents economic advantages, since these compounds are highly available and inexpensive. Therefore, the present study aimed to evaluate their qualitative chemical composition followed by multivariate analysis, and to correlate the results with those of the

Properties of Cellulose Microfibers Extracted from Pineapple Leaves by Steam Explosion

Advanced Materials Research, 2015
The aim of this work is to compare properties of cellulose mats from pineapple leaf fibers with and without using the steam explosion method. Pineapple leaf fibers were divided into two groups. The first group was chemically treated with sodium hydroxide for 24 h, and directly used to prepare cellulose mats.
