Biomedical Importance of Proteins

What are the functions of proteins in the human body?

• Proteins play a crucial role in building and repairing tissues.

• Proteins are mainly responsible for energy storage.

• Proteins are involved in the transport of oxygen in the blood.

Define amino acids and its classification.

• Amino acids are classified into carbohydrates, proteins, and lipids.
• Amino acids are classified into essential, non-essential, and conditional amino acids.
• Amino acids are classified into primary, secondary, and tertiary types.
• Amino acids are only found in animal sources and not in plants.

What are the essential functions of amino acids in the human body?

• Amino acids play a crucial role in muscle repair and growth.

• Amino acids are solely responsible for energy production in the body.

• Amino acids are not involved in any metabolic processes.

What are the main types of proteins based on their structure?

• Proteins can be categorized into structural, transport, and storage proteins.

• Proteins are classified into simple and complex proteins.

• Proteins can be divided into enzymes and hormones.

Describe the role of ribosomes in protein synthesis.

• Ribosomes are the sites where amino acids are linked together to form proteins.

• Ribosomes are responsible for DNA replication.

• Ribosomes are involved in the breakdown of proteins.

What are the physical properties of amino acids?

• Amino acids are only found in animal proteins and not in plants.
• Amino acids are polar, can form zwitterions, vary in solubility, and have distinct melting points.
• All amino acids are soluble in water and have the same melting point.

What are the chemical properties due to the COOH group?

• The COOH group is acidic, can donate protons, and participates in hydrogen bonding.
• The COOH group is non-polar and hydrophobic.
• The COOH group is a strong base.

What are the chemical properties due to the NH2 group?

• The NH2 group is acidic and cannot form hydrogen bonds.
• The NH2 group is a strong oxidizing agent.
• The NH2 group is only soluble in non-polar solvents.
• The NH2 group exhibits basicity, nucleophilicity, and can participate in hydrogen bonding.

What is the biomedical importance of amino acids?

• Amino acids are primarily used for energy storage.
• Amino acids are only important for muscle growth.
• Amino acids are vital for overall cellular function.

How are proteins classified based on shape and size?

• Proteins are classified into globular and fibrous.

• Proteins are classified into saturated and unsaturated.

• Proteins are classified into primary and secondary structures.

• Proteins are classified into enzymes and hormones.
