1. Inc/dec. of temp (high temp = denature 2. Inc/dec. of pH 3. Increase of salt

a structure sequence of amino acids «strung like pearls».

formed by folding the chain itself and results from interactions between amino acids chains. 1. An amino acid prefers a polar environment (attraction to water). 2. Amino acids of opp. charge form…

a. Support – b. Storage/acids – c. Transport (hemoglobin) – d. Communication (hormones) – e. Receptors (cell membrane proteins) – Reactions (enzymes).

found in the fungal cell wall and exoskeletons of insects.

when 2 or more chains of amino acids (polypeptides) associate to form the complete protein.

release energy by breaking molecules

1. Body temp 2. pH 7 3. Salinity (amount of salt in solution) 4. V-max reached (highest rate/reaction)

Circulates the blood in the body and provides a main energy source, and occurs in 2 forms.

Polymer of glucose; made by plants for structural cell walls. [Starch cannot digest cellulose because of the hydrolyzed bonds. It is used by the metabolism.]
