  • Amino Acid Side Chains
    1,776 words
    1. Describe The Devices And Processes That Govern The Creation Of A Functional Domain In Any Enzyme. When discussing enzymes, one must have an excellent understanding of proteins, because nearly all enzymes are proteins. Enzymes are proteins that carry out specific functions such as bind molecules with a high degree of specificity or carry out chemical reactions. They catalyze such chemical reactions that would control the flow of particles through membranes, control the concentration of certain...
  • Catalytic Sites Of Multi Domain Proteins
    1,451 words
    Describe the Nature, Structure, and Function of Domains in Proteins Domains " Within a single subunit [polypeptide chain], contiguous portions of the polypeptide chain frequently fold into compact, local semi-independent units called domains. ' - Richardson, 1981 In the hierarchical organisation of proteins, domains are found at the highest level of tertiary structure. Since the term was first used by Wetlaufer (1973) a number of definitions exist reflecting author bias, however all of the defin...
  • Most Basic Level Of Protein Structure
    1,018 words
    Proteins are the macromolecules of life. Discovered in 1838, proteins are recognized as a large number of superior organic compounds that make up living organisms and are essential to their functioning. The term protein comes from the Greek word proteins or primary. Proteins have many different properties and function in a variety of ways. They can function as a building material, in teeth, bones and muscles, and they can serve as enzymes, hormones, and neurotransmitters. Its functions are the m...
  • Four Basic Levels Of Protein Organization
    838 words
    Protein synthesis is one of the most fundamental biological processes. To start off, a protein is made in a ribosome. There are many cellular mechanisms involved with protein synthesis. Before the process of protein synthesis can be described, a person must know what proteins are made out of. There are four basic levels of protein organization. The first is primary structure, followed by secondary structure, then tertiary structure, and the last level is quaternary structure. Once someone unders...
  • Protein's Structure Through X Ray Crystallography
    1,744 words
    Proteins are a basic building block of life on earth. They are the molecules that provide structure, produce energy, and allow communication, movement and reproduction within a cell. They, along with carbohydrates, amino acids, and phospholipids, are the key macromolecules that make up organisms. The body of proteins that make up an organism is referred to as its proteome. Proteomics is the study of these proteomes, including the identification of the proteins and their physiological functions. ...
