Q

The structure, where amino acid chain twists into a helix or folds into a sheet

A

Secondary (2°) structure

18
Q

Loss of function

19
Q

what factors can denature a protein?

A

heat, excessive salt, or wrong ph

20
Q

proteins can have a variety of structures and functions due to the fact that

A

The 20 different types of amino acids can be assembled in a variety of orders

21
Q

because higher levels of protein structure depend upon the amino sequence of the ______ structure, a genetic mutation that causes a change in an amino acid can result in a misfolded, nonfunctional protein.

22
Q

contains starch

A

Potatoes, rice, and wheat

23
Q

What is a key difference between cellulose and starch?

A

The bonds between the subunits are oriented differently

24
Q

proteins can have a variety of structures and functions due to the fact that

A

The different types of amino acids can be assembled in a variety of orders

25
Long chains of amino acids (100 or more) linked through dehydration, synthesis form am molecule called
polypeptide
26
in the sentences of proteins, dehydration, reactions for peptide bonds between _______ monomers
amino acid
27
A proteins hydrogen bonds are broken and it's structure and folded when the protein
Is denatured
