Chapter 6

Front

Describe the structure, composition, and function of proteins.

Back

Proteins are made of amino acids linked by peptide bonds.

They function in tissue building, enzymes, hormones, and transport.

Front

What makes the structure of each protein different?

Back

The sequence and number of amino acids determine the protein's unique shape and function.

Front

How are amino acids linked together to form proteins?

Back

By peptide bonds formed during dehydration synthesis.

Front

What are the functions of protein?

Back

Structure, enzymes, transport, hormones, immune defense, and energy (if needed).

Front

Why are all essential amino acids required for protein synthesis?

Back

Without all essential amino acids, the body cannot build complete proteins.

Front

How many essential amino acids are there?

Back

9 essential amino acids.

Front

What is protein turnover?

Back

The continuous breakdown and synthesis of body proteins.

Front

What is protein denaturation?

Back

The unfolding of a protein due to heat, acid, or agitation, altering its function.

Front

Describe enzymes.

Back

Enzymes are proteins that speed up chemical reactions without being consumed.

Front

What is protein quality and digestibility?

Back

Protein quality is based on amino acid content and digestibility refers to how well protein is absorbed.
