PPT-Proteins – Structure and Function

Introducing proteins Proteins are a diverse group of large and complex polymer molecules made up of long chains of amino acids They have a wide range of biological roles including structural.

Characterization . and properties of IDPs. . Functional repertoire of IDPs. 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).. By: . Hemangi. . Atalia. introduction. Cell is the structural and functional unit of life.. Cells Tissue Organ . Organ. system.. Cells contain a variety of Internal Structures called . PROTEIN STRUCTURE. To understand how drugs interact it is necessary to understand their structure.. Proteins have four level of structure:-. PRIMARY . SECONDARY. TERTIARY. QUATERNARY. 1.PRIMARY STRUCTURE:-. Proteins account for more than 50% of the dry mass of most cells. Protein functions include structural support, storage, transport, cellular communications, movement, and defense against foreign substances. Proteins. The Role of Enzymes. Success criteria. By the end of this lesson we will be able to:. State what elements are found in proteins. Describe what is meant by primary, secondary and tertiary structure of proteins.. Cytoplasm.  . Cytoplasm . material between plasma membrane& nucleus. site of most cellular activity. 3 elements. Cytosol. Organelles. Inclusions . Cytosol. . viscous, semitransparent fluid in which other elements in cytoplasm are suspended. 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. Each amino acid (aa) shares a common structure; i.e. an amine (NH. 2. ) group, an acid group (COOH), and a central carbon atom bonded to hydrogen and to a side chain (R).. The side chains qualify aas as acidic, basic, neutral, aromatic, and sulphur-containing amino acids.. for . life.. . The importance of proteins was recognized by chemists in the early 19th century, including Swedish chemist . Jöns. Jacob Berzelius. , who in 1838 coined the term . protein. , a word derived from the Greek . Dr. . Shaimaa. . Munther. . Learning Outcomes - Proteins. Define the levels of protein conformation and to indicate the role of weak interactions.. Illustrate how protein structure relates to protein function using examples..
