13.6 Applications of Biochemistry

Introduction

Biochemistry is the branch of science dedicated to the study of the chemical processes within a cell.

The findings of biochemistry are applied primarily in medicine, nutrition, and agriculture. In medicine, biochemists investigate the causes and cures of diseases. Several blood tests are carried out to detect the presence of disease, monitor its progression, and evaluate the effectiveness of treatments.

This section explains some important applications of biochemistry in medicine and health.

Definition

Applications of Biochemistry: The practical uses of biochemistry in medicine, nutrition, and agriculture.

In simple words: Biochemistry is used in medicine to diagnose diseases, monitor health, and guide treatment.

Core Concept

Key point: Biochemistry has many important applications in medicine, including blood tests, pregnancy tests, cancer screening, and parental screening tests.

Detailed Explanation

What is Biochemistry?

Biochemistry is the branch of science dedicated to the study of the chemical processes within a cell.

• The findings of biochemistry are applied primarily in medicine, nutrition, and agriculture.
• In medicine, biochemists investigate the causes and cures of diseases.

Key point: Biochemistry is the study of chemical processes within cells. Its findings are applied in medicine, nutrition, and agriculture.

1. Blood Tests

What it is: A blood test is carried out with a blood specimen that measures the concentration of certain chemicals in a blood sample.

Why it is important:

• Blood tests are essential for understanding the body's internal function and balance.
• They analyze various breakdowns in the blood, including:
• Ions
• Enzymes
• Sugars
• Lipids
• Proteins
• Blood chemistry tests provide significant information about how well our kidneys, liver, and other organs are working.

Key point: Blood tests measure the concentration of chemicals in the blood and provide important information about organ function and overall health.

2. Pregnancy Test

What it is: A pregnancy test can analyze the state of pregnancy by checking a sample of urine or blood for a specific hormone.

The hormone: The hormone is called human chorionic gonadotropin (hCG).

How it works:

- High levels of hCG are a sign of pregnancy.

Key point: A pregnancy test detects the hormone human chorionic gonadotropin (hCG) in urine or blood. High levels of hCG indicate pregnancy.

3. Cancer Screening

What it is: Cancer screening is a test that looks for early signs of cancer in people without symptoms.

Why it is important:

• It can help spot cancer at an early stage when treatment is more likely to be successful.
• Cervical screening can even prevent cancer from developing.
• Cancer screening is for people with no symptoms at all.

Key point: Cancer screening looks for early signs of cancer in people without symptoms. Early detection improves the chances of successful treatment.

4. Parental Screening Tests

What it is: A parental screening test helps to:

• Identify genetic disorders
• Assess the risk of inherited conditions
• Prevent transmission of infectious diseases
• Prepare parents for the care of their children

Why it is important:

• Parental screening empowers parents to take proactive steps to safeguard the health and well-being of their family.
• Reproductive genetic carrier screening describes a screening test carried out before pregnancy or in early pregnancy.
• It is used to identify a couple's chance of having a child with a serious genetic disorder.

Key point: Parental screening tests help identify genetic disorders, assess the risk of inherited conditions, prevent transmission of infectious diseases, and prepare parents for the care of their children.
