Chapter 6 – The Proteins and Amino Acids Chapter Learning Objectives

6.1 State why some amino acids are essential, nonessential, or conditionally essential to the human body, and outline how the body builds a protein molecule.
6.2 Describe the digestion of protein and the absorption and transport of amino acids in the body.
6.3 List the roles that various proteins and amino acids can play in the body, and describe the influence of carbohydrate on amino acid metabolism.
6.4 Compute the daily protein need for a given individual, and discuss the concepts of nitrogen balance and protein quality.
6.5 Discuss potential physical problems from an eating plan that is too low or too high in protein.
6.6 Identify protein-rich foods, and list some extra advantages associated with legumes.
6.7 Summarize the health advantages and nutrition red flags of vegetarian diets, and develop a lacto-ovo vegetarian eating pattern that meets all nutrient requirements for a given individual.

True/False Items

1. Sickle-cell disease is an example of an inherited mistake in the amino acid sequence.
2. For the majority of exercisers, adding excess protein or amino acid supplements to an adequate diet will stimulate muscle building.
3. Some foods are so high in acid that they are capable of making the acid in the stomach even stronger.
4. Amino acid supplements are easy to digest and can relieve the digestive system from overworking.
5. When a person ingests a large dose of any single amino acid, absorption of others of its type may be limited.
6. If needed, protein can help to maintain a steady blood glucose level and so meet the glucose needs of the brain.
7. Many healthy people can consume less than the recommended amount of protein and still meet their bodies’ protein needs.
8. Without critical essential amino acids to perform their roles, many of the body’s life-sustaining activities would come to a halt.
9. Overconsumption of protein-rich foods offers no benefits and may pose health

    A). The chemical composition and structure of proteins seems quite confusing at first but one it is broken down into levels it is much more understandable. Amino acids are the basic building blocks of proteins and they contain amino, carboxyl and R groups. These R groups that are in the amino acids are what determine the properties of the specific amino acids. For structure, there are 4 levels. The first one being the primary level. These are made up of sequences of amino acids and these amino acids are linked together by peptide bonds. The next level is called secondary. This level is a formation of amino acid chains folded together by a helix formation or a pleated sheet. The bonds between…

    The first half of module seven discussed protein digestion, absorption, and metabolism; while the second half focused on pathological stress and kidney disease. Protein digestion occurs in the stomach and small intestine. When a protein reaches the stomach it is denatured by hydrochloric acid. Once the protein is digested pepsin breaks apart the denatured protein into peptides. Peptides move into the small intestine where they encounter an enzyme that digest the peptides into di- or tripeptides, then into single amino acids. Once the protein is digested into single amino acid groups, then the amino acids can be absorbed into the intestinal epithelial cells. The amino acids are moved from the intestinal epithelial cells into the capillaries of the intestinal villi. From the capillaries of the intestinal villi,…

    Amino acids are biologically organic compounds containing amine and carboxylic acid functional groups, usually along with a side-chain specific to each amino acid. The elements that are key of an amino acid are carbon, hydrogen, oxygen, and nitrogen. There are about 500 different kinds of amino acids found but we recognize 23 of the amino acids that are known, they are classified into three groups, essential semi-essential, and non-essential. Each amino acid has unique characteristics arising from the size, shape, solubility, and ionization properties of its R group. In the form of proteins, amino acids comprise the second-largest component of human muscles, cells and other tissues, water being first. Outside proteins, amino…

    Carbohydrates, proteins and lipids are identified as macronutrients. The carbohydrates, proteins and lipids are all sources of energy for the body to function. When insufficient macronutrients are received the individual would become severely fatigue, and acceptable to chronic diseases. To keep the adequate amounts of macronutrients is important to maintain being healthy. Every cell in the body has protein, when not consuming enough protein the body will have difficulty functioning. Without sufficient amount of proteins, the concentration of protein would drop below normal levels in the bloodstream (Wardlaw & Smith, 2011, p. 221). Without macronutrients the body would become malnourished, suffering from fatigue, and decreased organ size with possible…

    However, proteins are made of subunits called amino acids, and the breakdown of a very important group of amino acids called the branched-chain amino acids is regulated by the activity of an enzyme called BCOAD. As you might expect, a diet which is very rich in protein leads to an increase in BCOAD activity in the liver. On the other hand, when athletes step up their carb intakes, BCOAD activity drops. Thus, luxuriant carbohydrate ingestion seems to spare protein by calming down…

    Proteins are large, complex molecules that are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein. The sequence of amino acids determines each proteins unique structure and specific function. They play many critical roles in the cells. They can be grouped as enzymes, antibodies, messengers, structural components or transporters, according to their functions.…

    Amino acids are the basic building blocks of proteins that are joined by peptide bonds to form a peptide chain. These chains then conform to a special arrangement and interact with other peptide chains forming complex macromolecules known as proteins (Horton, et al., 1996). The amino acid content of a particular protein of interest can be determined and extracted through solubilization using detergents (Carpentier, et al., 2005).…
