PPT-Proteins

The 411 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. Introduction:. Plasma proteins are:. Serum albumin.. Serum globulin.. Fibrinogen.. Serum contains albumin and globulin.. Fibrinogen is absent . Converted into fibrin during blood clotting.. Therefore albumin and globulin are called serum albumin and serum globulin.. 2. 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. The 20 different amino acids. 7.5.1: Explain the four levels of protein structure, indicating the significance of each level.. Peptide bonds link the amino acids together . Polypeptide with five amino acids. . The 20 different amino acids. 7.5.1: Explain the four levels of protein structure, indicating the significance of each level.. Peptide bonds link the amino acids together . Polypeptide with five amino acids. . Protein. The . main function of protein is to . build and repair tissues . (muscle tissue). Protein. Protein can be a source of energy but should be used as a last resort. . from lack of structure to. pleiotropy. of functions. Lilia Iakoucheva. University of California, San Diego. OUTLINE. Characterization . and properties of IDPs. . Functional repertoire of IDPs. 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). CHAPTER 3, Part 1 . Amino Acids and Peptides . To know the structure and naming of all 20 protein amino acids. To know the structure and properties of peptides and the particularly the structure of the peptide bond.. 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).. B.2. Properties of 2-amino acids . (B.2.2). Zwitterion. (dipolar) . amino acids contain both acidic and basic groups in the same molecule . therefore, are . amphoteric. in nature (capable of behaving as acids or bases). Different types of . mb. proteins require different conditions for . mb. release. Integral membrane proteins directionally insert in the membrane bilayer. Outside cell. Inside cell. Glycophorin. and . Unit objectives:. Identify amino acid classifications based on nutritional use and chemical properties of side chains. Describe the primary, secondary, tertiary and quaternary structures of proteins. 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%). Unit 1 Advanced Higher. Miss Aitken. Pages 16-25. Textbook. Proteomics. Genome:. complete set of DNA. Comprises of coding and non-coding areas. 20-25000 genes in human genome. Proteome:. Entire set of proteins that can be expressed from a genome.
