Describe the structural or environmental change of your chosen macromolecule. Then predict the effect this change will have on t
Wewaii [24]

Answer:

Choosing protein as macromolecule.

Explanation:

The given environmental changes can lead to structural changes in protein as well:

pH - Several amino acids contain sidechains with practical gatherings that can promptly pick up or lose a proton. Changes in pH would prompt an adjustment in the charge of the amino acids, prompting charge-charge attraction or repilsion between non-interfacing amino parts.  

Temperature - High temperatures can prompt protein denaturation. Warmth can upset hydrogen bonding and hydrophobic interactions.  

Reduction or oxidation Environment - Some tertiary structure of protein folding is held by disulfide linkages. Reducing agent will lead to unfolding by introducing itself to break disulfide bonds.

Effect of these change: Sequence of amino acid and structure of protein molecule form determines function, any slight change to a protein's structure may result in the protein to become dysfunctional or produce different product.
