Lecture Objectives

After completion of this lesson, learner can be able to:

1. Describe role, value, sources of Protein

2. Describe role, need, sources of Lipid3. Describe role, value, need, sources of

Carbohydrate

Overview

Where is our energy source from?

The nutrients provide energy:

- Protein- Lipid- Carbohydrate

Protein

There are 2 kinds: Simple Protein: only amino acids Complex Protein: apart from amino

acids, there are nucleic acids, carbohydrates, lipids

The role of Protein Cell Structure Necessary for the normal metabolism

of other nutrients Provide energy Homeostatic Protect and detoxify Stimulate appetite

The role (1) of ProteinCell Structure: build

and regenerate tissue

Cell core: DNA, RNA Cytoplasm Other: globulin, …

The role (2) of Protein

Necessary for the normal metabolism of other nutrients: Enzyme

The role (3)of ProteinProvide energy

1gr => 4 Kcal 10 – 15% ration

energy

The role (4) of Protein Homeostatic: stabilize blood PH =

glue Protein

H+OH –

The role (5) of Protein Protect and

detoxify: Antibody is protect

Protein

The role (6) of Protein Stimulate appetite:

Adult, Protein is distributed as follows: 1/3 in muscle, 1/5 in bone and cartilage, 1/10 in leather.

Value of ProteinValine

Isoleucine

Leucine

Lysine

Methionin

PhenylalaninThreonine

Tryptophan

Essential Amino acids:

the human body does not produce

themselves

HistidineArginine

Sources of ProteinFrom animals- Meat- Fish- Egg- Milk

Sources of Protein

From plants Beans: soybean, blue bean, … Cereals: rice, wheat, grist, … Vegetables: potato, carrot, kohlrabi,

…
