Dengue is the most prevalent mosquito-borne viral infection
worldwide. Over half of the world's population live in areas at
risk of dengue infection. The disease is transmitted principally by
Aedes spp. mosquitoes. Dengue Outbreaks were recorded in all
countries of the Indian Subcontinent with Pakistan, India,
Bangladesh and Sri Lanka resulting in huge number of cases and
deaths. It is a disease caused by four serotypes of a same virus
i.e. DENV1, DENV2, DENV3 and DENV4. In all major outbreaks, DENV2
and DENV3 were recorded as dominating and disastrous serotypes in
the region. Climate is a vital factor influencing DF outbreaks;
temperature, humidity, rainfall and flood play a fundamental role
in DF outbreaks, as providing optimum conditions for vector
population growth.Presently, prime prevention of dengue is possible
only with vector control and personal protection from the bites of
infected mosquitoes.

Enzymes are biological catalysts which accelerate the chemical
reactions in living things without being consumed. A catalyst is a
material which builds a chemical reaction goes faster, without
itself being altered. A catalyst can be utilized again and again in
a chemical reaction: it is available again for same function.
Enzymes are exceptionally the same apart from that they are simply
denatured by heating. This book discussed about the history of
enzymes, Production criteria, biotechnology, classification,
Kinetics and Enzyme applications. Enzyme biotechnology involves the
utilization of microorganisms such as yeast, mold or bacteria, and
enzymes to make goods and services is a promising field in modern
biotechnology. I am looking forward to work in a professional and
competitive environment where It can put my best efforts, hard work
and skills to bring up the organization and myself too. I am also a
life long learner and am determined to become a knowledge
professional for keeping abreast with changing technology.
Pigments or biochrome are the substances present in all living
matter and play basic roles in the development of living organisms
including plants. Plants use these pigments for the variety of
functions including photosynthesis, signaling, to ward off
herbivores and attracting pollinating and dispersal agents. The
most common plant pigments are chlorophylls, carotenoids, betalains
and anthocyanins. In fact, chlorophylls are the most important
organic compounds, essential for photosynthesis. Carotenoids
presents in plants are usually play their roles in both nutrition
and photosynthesis and are necessary for the survival of both
mammals and plants. They also served as precursors of plant hormone
abscisic acid in higher plants. Another role of carotenoids is to
protect photosynthetic organisms against potentially harmful
photooxidative processes. Betalains are nitrogen containing water
soluble compound, belonging to the families of Caryophyllales,
except for Caryophyllaceae and Molluginaceae. Betalains are
classified into yellow betaxanthins and red betacyanins and are
immonium conjugates of betalamic acid. Anthocyanins are water
soluble vacuolar pigments belonging to flavonoids. They appear in
plants as blue, red or purple depending on the pH and synthesized
through phenylpropanoid pathway. As these plant pigments are of
many roles including structural to physiological functions in cells
therefore special consideration has been given in this book to
their salient characteristics, some biosynthesis and their chemical
and biochemical role in different fields. Special attention is also
given to specific role of these plant pigments in bioassays
regarding the human health. Methodological applications for these
pigments are also deeply demonstrated in few chapters including the
In silico study for diversifying the molecular pathway of pigment
formation.
