, MINERALS
INTRODUCTION
1. There are 29 different types of elements in our body
2. The mineral elements constitute only a small proportion of the body
weight and there is a wide variation in their body content
3. Minerals perform several vital functions which are absolutely essential
for the existence of man
4. These functions include calcification of bone, blood clotting,
neuromuscular irritability, acid base balance and water-electrolyte
balance
CLASSIFICATION
The elements of the body are divided into 5 major groups
GROUP 1
1. These are components of macromolecules such as carbohydrates, proteins
and lipids.
2. Examples
a) Carbon (C)
b) Hydrogen (H)
c) Oxygen (O)
d) Nitrogen (N)
, GROUP 2
1. These are nutritionally important minerals or principal elements
2. Their daily requirement is more than 100 mg
3. Their deficiency can prove fatal
4. They are also known as macro elements
5. Examples
Sodium (Na)
Potassium (K)
Chloride (Cl)
Calcium (Ca)
Phosphorus (P)
Magnesium (Mg)
Sulfur (S)
