2. PROTEINS
• Proteins are large, complex molecules that play many
critical roles in the body. They do most of the work in
cells and are required for the structure, function, and
regulation of the body’s tissues and organs.
3. WHAT IS THE MONOMER OF
PROTEIN?
Amino acids are the monomers that make up proteins
4. PROTEIN STRUCTURE
Proteins structure can be discussed in terms of four levels of structures;
primary, secondary, tertiary, and quaternary. The primary structure of a
protein is its amino acid sequence. There are two types of secondary
structures; α-helix and β-sheet. The tertiary structure of proteins is
determined by the three-dimensional structure, which can be either
globular or fibrous. Tertiary structure is more complex and compact.
Quaternary structure of a protein is far more complex due to its higher
degree of folding patterns. Most of the proteins with quaternary
structure, contain subunits, which are held together by non-covenant
bonds. For example, haemoglobin has four subunits.

6. WHAT IS THE MAIN FUNCTION
OF PROTEIN?
• Proteins are the building blocks of life.
Every cell in the human body contains
protein. The basic structure of protein is a
chain of amino acids. You need protein in
your diet to help your body repair cells
and make new ones.
7. • Proteins are responsible for nearly every
task of cellular life, including cell shape
and inner organization, product
manufacture and waste cleanup, and
routine maintenance. Proteins also receive
signals from outside the cell and mobilize
intracellular response.
8. MEAT AND FISH
A type of macronutrient.
Proteins are made up of
chains of amino acids. They
do most of the work in cells
and are required for the
structure, function, and
regulation of the body's
tissues and organs
9. EGGS
The protein in eggs helps
maintain and repair body
tissues, including muscle. Brain
health: Eggs contain vitamins
and minerals that are necessary
for the brain and the nervous
system to function effectively.
Energy production: Eggs contain
all the nutrients that the body
needs to produce energy
10. SEEDS AND NUTS
Nuts and seeds are good sources
of protein, healthy fats, fibres,
vitamins and minerals. Nuts and
seeds regulate body weight as their
fats are not fully absorbed and they
regulate food intake. Nuts and
seeds contain unsaturated fats and
other nutrients that provide
protective effects against heart
disease and diabetes.
