Outline Of Proteins

Proteins I. Introduction Bio chemical reactions are turnd by enzymes Structure of cells and the extracellular matrix that surrounds the cells (e.g. collagen) Transport of materials (e.g. transferrin), receptors for hormone, transcription factors Makeup of antibodies II. Synthesis and catabolism [pic] [pic] Disintegration of protein to amino group group stingings o Lysosomal alley degrades extracellular proteins o Cytosolic pathway degrades intracellular proteins Transamination o important reaction that remove amino acid nitrogen from the corpse III. Structure Levels of protein structure Primary ? Amino acids in a specific sequence Secondary ? on a reparation basis repeating structures stabilized by hydrogen bonds amongst the amino acids with in the protein ? ?-helix and ? pleated sheets ? Adds strength and flexibility to the protein Tertiary ? Overall, shape, embodiment (fold) of the protein corpuscle ? Due to interaction of side chains (e.g. hydrophobic effect, hydrogen bonds, etc.) ? Function, physical and chemical properties depend on this quaternity ? Interaction of more than one protein molecule or subunits IV. classification Classification by Protein Functions |Classification |Function | |Enzymes |proteins that catalyze chemical reactions | |Hormones ! |Proteins that are chemical messengers that control the actions of specific cells or variety meat | | |Affect growth and development, metabolism,...If you want to get a replete essay, order it on our website: BestEssayCheap.com
