Proteins. Proteins are polymers made of monomers called amino acids. All proteins are made of 20 different amino acids linked in different orders. Proteins are used to build cells, act as hormones & enzymes, and do much of the work in a cell. Dina N Kovarik, MS, PhD. Digital World Biology. Updated . April 24, 2015.

TRAISH) Introduction to Proteins - Proteins are abundant and functionally diverse molecules - They participate in cell regulation at all levels - They share a common structural Importance, Characteristics, Structure, Classification, . Denaturation. Importance. Major structural components of animal tissues. Involved in the maintenance of life processes as communication (nerves), defense (antibodies), metabolic regulation (hormones), biochemical catalysis (enzymes), and oxygen transport (hemoglobin). Levels of Protein Structure. Primary 1º Structure. The primary structure is simply the sequence of amino acids in a protein.. Chains of amino acids are written from the amino terminus (N-terminus) to the carboxyl terminus (C-terminus).. 2. Proteins (. Polypeptides. ).

In order to survive, the human body needs the nutrients found in food. These nutrients, which perform a number of life-sustaining functions in the body, are divided into 6 main categories: carbohydrates, proteins, fats, vitamins, minerals and water. Each has a unique function in the normal growth and repair of the body.. 4. calories per gram. . The main function of protein is to . build and repair body tissues. .. If carbohydrates and fat are not available, your body will use protein. Is this a good thing? . You must eat protein . proteins of milk, meat and eggs.. Milk composition. Deficient in iron and vitamin C. Milk proteins. Total protein content in milk – 2.9 – 3.5%. Two major types of milk protein. Caseins (80%). Whey proteins: (20%). Most abundant molecule in cells making up 50% or more of their dry weight. Every protein has a unique structure, or shape. Allows it to perform a specific function. Enzymes are proteins that function as catalysts for many reactions in foods.
