Basics of Amino Acid Structure (Part 1)

The video tutorial covers the basics of amino acids and proteins, focusing on their functions, structures, and roles in biological systems. It explains how proteins are linear hetero polymers of amino acids and discusses their functions such as catalysis, transport, structure, and motion. The tutorial also highlights the importance of amino acids in energy production and their chiral nature, emphasizing the use of L isomers in biological systems.

What is the primary role of amino acids in relation to proteins?

• They provide structural support to cells.

• They act as enzymes in chemical reactions.

• They are used to store genetic information.

• They are the building blocks of proteins.

Which of the following is a function of proteins in the body?

• Providing energy storage

• Catalyzing biochemical reactions

• Storing genetic information

• Transmitting nerve impulses

What protein is responsible for transporting oxygen in the blood?

• Hemoglobin

• Collagen

• Keratin

• Myosin

Which proteins are involved in muscle contraction?

• Hemoglobin and collagen

• Myosin and actin

• Keratin and elastin

• Enolase and DNA polymerase

What is the significance of the L and D isomers in amino acids?

• They are important for protein recognition and function.

• They affect the solubility of proteins.

• They determine the color of proteins.

• They influence the taste of proteins.

Which amino acid is achiral?

• Alanine

• Glycine

• Asparagine

• Glutamate

Why are L isomers of amino acids predominantly used in human proteins?

• They are more stable than D isomers.

• They are easier to digest.

• They are more abundant in nature.

• They are recognized by ribosomes during protein synthesis.
