At the end of the lesson, the learners should be able to…
I. OBJECTIVES
1. Distinguish between carbohydrates, proteins, lipids, and nucleic acids
2. Summarize the general characteristics of each biomolecule
3. Relate the structures of the biomolecules with their properties
The Learner demonstrates understanding of…
A. Content Standards
the relationship between the function and structure of biological
macromolecules.
The Learner is able to…
B. Performance Standards
make a presentation of some diseases that are associated with the various
organ systems.
The Learner…
C. Learning Competencies/
Objectives (Write the LC
code for each)
II. CONTENT
explain how the structures of biological macromolecules such as carbohydrates,
lipids, nucleic acid, and proteins determine their properties and functions.
How the properties of matter relate to their chemical structure

IV. PROCEDURES
A. Reviewing Previous lesson
or presenting the new lesson.
B. Establishing a purpose for
the lesson.
Review on the previous lesson.
Check the assignment.
Ask learners what they know about fats and oils. Expect answers relating to
sources, health benefits, harmful effects and properties such as insolubility in
water.
C. Presenting examples/
instances of the new
lesson.
Lipids
Lipids provide more energy per gram than carbohydrates and proteins They
provide 9 kilocalories of energy per gram! Aside from being an energy source or
storage, lipids also serve other functions such as material for cell membrane,
insulation to maintain body temperature, aid in digestion, and as signal
molecules.
Proceed to the different classifications of lipids. Enumerate the different
classifications: triglyceride, phospholipid, wax, and steroid. Mention that the lipid
family is one of the most varied in terms of structure but they share the common
property of being insoluble in water.
D. Discussing new concepts
and practicing new skills
#1.
Present a Power Point Presentation which tackles Lipids furthers.
E. Discussing new concepts
and practicing new skills
#2.
F. Developing mastery (Leads

G. Finding practical
applications of concepts
and skills in daily living.
Lipids
The word lipid comes from the Greek word lipos which means fat. Lipids are a
family of biomolecules
having varied structures. They are grouped together simply because of their
hydrophilic property
(water-fearing). They are soluble in non-polar solvents such as ether, acetone,
and benzene. Lipids
can be classified into four categories:
a. Wax
b. Triglycerides
c. Phospholipids
d. Steroids
The discussion on lipids will be limited to fatty acids, triglycerides, and
phospholipids as these are
enough examples to show the relationship of lipid structure to function and
properties.
Fatty acids
Understanding fatty acids is essential to understanding lipids. Fatty acids are
long-chain carboxylic
acids that are insoluble in water. Fatty acids can be saturated or unsaturated.
Understanding
fatty acids is essential to understanding lipids. Fatty acids are
Saturated fatty acids
long-chain carboxylic
acids that are insoluble in water. Fatty acids can be saturated or unsaturated.
Saturated fatty acids
contain single bonds in its hydro-carbon chain whereas unsaturated fatty acids
contain double
bonds.
H. Making generalizations
and abstractions about the
lesson.
I. Evaluating learning.
J. Additional activities for
application or remediation.
Written exam
1. Why are nucleic acids named so?
- Around 1868, Friedrich Miescher isolated an unknown weakly acidic substance from
the nucleus of white blood cells, hence the term
nucleic acid.
2. What comprises nucleic acids?
- Nucleic acids are composed of nucleotides.
3. What is another term for nucleic acids?
- Nucleic acids are also known as polynucleotides.
4. What are the three parts of a nucleotide?
- A nucleotide has a five-carbon sugar, a phosphate group and a nitrogenous base
5. What are common examples of nucleic acids?
- DNA and RNA
6. What is the primary role of DNA?
- It is the blueprint of life. Our genetic code is found in the DNA.
7. How does RNA help in protein synthesis?
- RNA helps in protein synthesis by carrying out the instructions encoded in the DNA.
8. What are the bases of DNA? of RNA?
- DNA: Adenine, Guanine, Tyrosine, Cytosine RNA: Adenine, Guanine, Uracil, Cytosine
9. How are DNA and RNA similar?
- They have the same three bases: A, G, C.
- They both have nucleotides containing one phosphate group, a five-carbon sugar,
and a nitrogenous base.
- Both are used in the manufacture of proteins
10. How are DNA and RNA different?
- DNA is double stranded while RNA is single strand
- DNA has deoxyribose for its sugar while RNA has ribose
- DNA has thymine while RNA has uracil
Ask the learners to create a mind map of the things that they remember about
lipids. Help them by asking them to strive to
incorporate the following:
- elements found in lipids
- different classifications of lipids
- different examples and connect these to its function
Allocate a few minutes to clarify concepts, afterwards proceed to nucleic acid.
