Proteins proteins are unbranched repeating chains of amino acids (a. a) an a. a. are small molecules consisting of an amino group, a carboxyl carbon and hydrogen atom and a side chain the structure of the side chain distinguishes it from the other 20 a. a. Foods: meat, fish, milk, cheese, peanuts, dry beans, peas group, a

Functions of Protein

What does the body do with the Proteins we eat? Our digestive system breaks down food into individual molecules for our body to use. What does the body do with Protein? Proteins are broken down into amino acids; the body rearranges amino acids to create our own proteins. Use proteins for an energy source Click reveal when other nutrients aretolow.

Proteins There are 20 amino acids. 8 are considered essential, obtained in diet. Individuals should not rely on protein as an energy source since proteins cannot be stored in the same manner as carbs - if the body demands a. a. it will begin to digest proteins leading to serious Click to reveal tissue damage.

What is the process the body uses to create the energy we need? Cellular Respiration Check your answer here+ energy O 2 + C 6 H 12 O 6 CO 2 + H 2 O

Denatured Proteins may lose their shape if they are subjected to high temperatures (generally over 40 0 C) or exposed to acidic, basic, salty conditions A denatured protein cannot carry out its biological functions angerous fevers denature critical enzymes in the brain, leading to Click to reveal seizures and possibly death

1 Testing for Proteins Copy - Biuret reagent reacts with the bonds that join amino acids together - if protein is present solution will react with Biuret's and change colour to violet
