What is the primary function of proteins in the body?

Back

Proteins serve various functions including assisting in blood clotting, fighting infections, and facilitating biochemical reactions.

Front

What distinguishes one amino acid from another?

Back

The R group (or side chain) is what differentiates one amino acid from another.

Front

What is a macromolecule composed of a chain of amino acids called?

Back

A macromolecule composed of a chain of amino acids is called a protein, such as hemoglobin.

Front

Can the structure of proteins be altered by environmental factors?

Back

Yes, the structure of proteins can be changed by environmental factors such as temperature and pH.

Front

Which part of an amino acid varies among different amino acids?

Back

The R-group varies among different amino acids.

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins.

Front

What is the role of the amino group in an amino acid?

Back

The amino group (-NH2) is responsible for the basic properties of amino acids and participates in peptide bond formation.

Front

What is the significance of the carboxyl group in amino acids?

Back

The carboxyl group (-COOH) gives amino acids their acidic properties and is involved in peptide bond formation.

Front

What is denaturation in the context of proteins?

Back

Denaturation is the process where proteins lose their structure due to external stress, such as heat or pH changes, leading to loss of function.

Front

What is the quaternary structure of a protein?

Back

The quaternary structure refers to the arrangement of multiple polypeptide chains in a protein.
