What is the correct definition for protien? Will give 10 points!

any of all naturally occurring extremely dificult substances that consist of aminoacid residues joined by the peptide bonds, contain the elements carbon, hydrogen, nitrogen, oxygen, (usually sulfur), and occasionally other elements (such as phosphorus or iron), and include many essential biological compounds (such as enzymes, hormones, or antibodies) and yeah thats basicly the nerd definition.

some functions,

the proteins in foods allow certain reactions to occur during preparation:hydration, denaturation/coagulation, enzymatic reactions, buffering, and browning. Hydration. the ability of proteins to dissolve in and attract water, a process called hydration, allows them to play several important roles in foods.

what are the choices?
