Some Famous Filipino Chemists

DR. JULIAN A. BANZON

A biophysical chemist who did the

pioneering works on coconut as a source

of chemicals and fuels. He devised the

process of extracting residual coconut oil

by chemical means rather than by

physical means

DR. ALFREDO C. SANTOS

He gained recognition for his researches

on natural products. He did a lot of work

on alkaloids from indigenous medicinal

plants.

DR. LOURDES J. CRUZ

She has made significant contributions to

the biochemistry of toxic peptides from

venom of fish-hunting Conus marine

snails. Her studies led to the biochemical

characterization of active peptides from

Conus venom and the development of

conotoxins as biochemical probes

DR. LUZ OLIVEROS-BELARDO

A pharmaceutical chemist who worked on

the chemistry of natural products and

essential oils from most Philippines

plants. Her works resulted in the

production of new flavors and herbal

medications.

DR. BIENVENIDO O. JULIANO

An organic chemist who is concerned

with the properties of starch and protein

and other grain constituents in relation to

grain quality of rice.

CLARA Y. LIM-SYLIANCO

An organic chemist with an expertise on

mutagens, anti-mutagens and bio-organic

reactions. She has written numerous

scientific articles, books, monographs

and related materials. Some of her

books published are used as textbooks in

college chemistry.

DR. SOLITA CAMARA-BESA

A medical doctor by profession, she

worked on sodium and potassium content

of Philippine foods and established

standards useful in the preparation of

diets. Her analysis of cholesterol gave

the Filipino the idea of the importance of

diet especially on fats and cholesterol.

ANGEL C. ALCALA

Angel Alcala has more than thirty years of experience

in tropical marine resource conservational. Angel Alcala

is considered a world class authority in ecology and

biogeography of amphibians and reptiles, and is

behind the invention of artificial coral reefs to be used

for fisheries in Southeast Asia. Angel Alcala is the Director

of the Angelo King Center for Research and Environmental

Management.

SOME WORLD FAMOUS BIOLOGIST

Charles Darwin (1807-1882)

In biological science: formulated the Theory of Organic

Evolution; published the book title On the Origin of Species

which presented facts that all species of plants and animals

evolved from a few common ancestors.

William Harvey (1578-1657)

In physiology: discovered the mechanics of human

blood circulation; published An Anatomical Treatise on the

Motion of the Heart and Blood in Animals which is considered

today as the most important single volume in the history of

physiology.

Robert Koch (1843-1910)

In bacteriology: was known fpr his discovery of bacteria

causing anthrax, tuberculosis, and cholera; not only did hediscover the specific organisms causing specific diseases, but

also developed sanitary measures such as water filtration for

controlling the spread of water born diseases; also set forth four

principles known as Kochs Postulates for locating disease-

causing microorganisms which are now considered fundamental

in bacteriology.

Anton Van Leeuwenhoek (1632-1723)

First to observe spermatozoa, bacteria and protozoa

with his simple microscope; also gave the first clear description

of capillary circulation; made important observations on the

development of ants, mussels, the insect nature of cochineal,the spinning and poison apparatus of spiders.

Carolus Linnaeus(23 May 170710 January 1778)

He was a Swedish botanist, physician and zoologist who

created the binomial nomenclature. In this system, every kind

of animal and plant is given a name consisting of two Latin

words, for its genus and species. This became used by biologists

all over the world, and he is known as the "father of modern

taxonomy".

Sir Alexander Fleming (1881-1955)

In physiology: was awarded the 1945 Nobel

Prize in physiology and medicine for his discovery of the

antibiotic penicillin, the so-called wonder drug.

Main Parts of the Respiratory System and their Function

The nostrils: Nostrils are involved in air intake, i.e. they bring air into the nose, where air is warmed and

humidified. The tiny hairs called cilia filters out dust and other particles present in the air and protects

the nasal passage and other regions of the respiratory tract.

Trachea: The trachea is also known as windpipe. The trachea filters the air we inhale and branches into

the bronchi.

Bronchi: The bronchi are the two air tubes that branch off of from the trachea and carry atmospheric air

directly into the lungs.

Lungs: The main organ of the respiratory system is lungs. Lungs are the site in body where oxygen is

taken into and carbon dioxide is expelled out. The red blood cells present in the blood picks up the

oxygen in the lungs and carry and distribute the oxygen to all body cells that need it. The red blood cells

donate the oxygen to the cells and picks up the carbon dioxide produced by the cells.

Alveolus: Alveolus is the tiny sac like structure present in the lungs which the gaseous exchange takes

place.


7/9

Diaphragm: Breathing begins with a dome-shaped muscle located at the bottom of the lungs which is

known as diaphragm. When we breathe in the diaphragm contracts and flatten out and pull downward.

Due to this movement the space in the lungs increases and pulls air into the lungs. When we breathe

out, the diaphragm expands and reduces the amount of space for the lungs and forces air out.
