Discussion on biological macromolecules


Biological macromolecules are large,
organic
molecule
such
as
carbohydrates, lipids, proteins, and
nucleic acids. Most of them are
organic compounds and the functional
group determines their chemical
properties. Biomolecules have a huge
variety of functions, such as storing
energy, protection, etc. Now be ready
with your journey to the different
biomolecules, their structures, and
functions found in your food.

Discussion about carbohydrates
Discussion about lipids and fats
1. Carbohydrates
2. Lipids or fats


The word carbohydrate may be
broken down to carbon and hydrate.
Another term for carbohydrate is
saccharide. Carbohydrates are
classified either as simple or
complex. Simple sugars are
monosaccharide and disaccharides.
Complex
sugars
are
polysaccharides.
Carbohydrates are the primary
energy source of the human body.
The different saccharides that
humans eat are converted to glucose
which can be readily used by the
body. The excessive consumption of
carbohydrates is converted to
Lipids or fats are important
nutrients in your body but eating
too many especially unhealthy fats
such as saturated fats and trans fats
can lead to heart disease, cancer,
and obesity. Lipids also serve
other functions such as material
for cell membrane, insulation to
maintain body temperature, aid in
digestion, and as signal molecules.
Discussion about Nucleic Acids
4.Nucleic Acids

Nucleic acids play an essential role in
the storage, transfer, and expression of
genetic information. Nucleic acid was
discovered by a 24-year old Swiss
physician named Friedrich Miescher
in 1868. He was puzzled that an
unknown substance in white blood
cells did not resemble carbohydrates,
proteins, or lipids. He was able to
isolate the substance from the nucleus
and initially called it nuclein. He
eventually was able to break down
nuclein into protein and nucleic acids.
He found out that nucleic acids
contain carbon, hydrogen, oxygen,
nitrogen, and phosphorus.

and in muscles. Glycogen is a slowreleasing carbohydrate

D. Food is a source of molecules that are
needed for life. These are biological
molecules. What you eat belongs to
biomolecules. There are four
biological molecules that make up all
of life. Now, I have here a word hunt
for your warm up.
Look for the words and write your
answer: biomolecule, carbohydrate, lipid,
protein, and nucleic acid.

different
There are different classifications of
lipids: triglyceride, phospholipid, wax, and
steroid. The lipid family is one of the most
varied in terms of structure but they share
the common property of being insoluble in
water.

Discussion about the Examples of
Nucleic acid
The most common examples of nucleic
acids are DNA (deoxyribonucleic acid) and
RNA(ribonucleic acid). DNA is a nucleic acid
that carries the genetic code of organisms. It is
fondly termed as the blueprint of life. RNA, on
another hand, carries the information from the
DNA to the cellular factories for the synthesis

saccharide units, proteins of amino acids, and
Fat and oil are the most common lipids of fatty acids, nucleic acids are
examples of lipids. They are under composed of nucleotides. Nucleic acids are
triglycerides because they are composed of also known as polynucleotides.
glycerol and three fatty acids.
Fat refers to solid triglyceride usually from Three parts of nucleotide:
animal sources such as meat, milk, butter, 1. Nitrogenous base
margarine, eggs, and cheese. Oil refers to 2. Five-carbon carbohydrate or sugar
liquid triglycerides from plant sources. 3. Phosphate group
Examples are olive oil, corn oil, sunflower
oil, and soybean oil. Animal fats contain
high percentages of saturated fatty acids
while plant oils are mostly unsaturated
fatty acids.
Did you know that?
Marathon runners, tri-athletes, and other
runners eat carbohydrates for weeks
leading up to a big event. They call it
“carbo-loading”. What’s the point?
As the athletes consume massive amounts
of starch and pasta, the energy begins to
store up in their body, saving itself for use
during the event
Lipids
They are made from carbon, hydrogen, and
oxygen
They are soluble (dissolve) in oil but are
insoluble (don’t dissolve) in water.
Examples: fats and oils
Function: long-term storage of energy in
the body
Monomer: fatty acid

are:

1. Keratin is a structural protein found in
hair, skin, and nails.
2. Fibroin / Silk protein - Fibroin is found
in silk. Silk has a smooth and soft texture.
It is one of the strongest natural fibers that
have high resistance to deformation. It is
also a good insulating material.
3. Collagen is a major insoluble fibrous
protein found in connective tissues such as
tendons, ligaments, skin, cartilage and the
cornea of the eye. It comprises as much as
30% of proteins in animals.
4. Enzymes function to catalyze chemical
reactions. They either speed up a reaction,

Examples of enzymes
a. Lipase - help in digestion of fats
b. Pepsin - help in breaking down proteins
into peptides (smaller units)
c. Sucrase - also called invertase; help in
the digestion of sugars and starches
5. Myoglobin is a polypeptide that stores
oxygen in muscles. It contains a heme
group which has an iron where the oxygen
is stored.
