Tommy Lasater Justyn Encinas Meghan Bracy Kirsten Hudson Lisa Hull proteins Sebastian AP Bio 3rd period
3. Proteins are important because they are crucial to the function of living organisms 5 pt 2. A protein consists of one or more polypeptides that are folded and coiled into specific formations 4. The functions of proteins and living organisms include structural support, transport of other substance storage, movement, and defense against foreign substances.
2. Carbon, hydrogen, oxygen, nitrogen (CHON) 1. Amino acids, and polypeptides 6. Peptide bonds 16 pt 2. 100,000 sequences 7. Carboxyl and amino acid groups 5. polypeptides
16 Pt 1. Scientists know the shape of approximately 10,000 proteins 9. X-Ray crystallography is used to determine the 3-D structure of a protein. It does this by deflecting an X-ray off individual atoms in a crystal of the protein. Spatial coordinates are determined and a model is built from the results. 15. The 3-D conformation is determined by the amino acid sequence of a polypeptide
Secondary (coils and folds in the polypeptide chain) primary structure (unique sequence of amino acids) quaternary (the overall protein structure resulting from the aggregation of two or more polypeptide subunits. tertiary (irregular contortions from interaction between side chains of various amino acids)
8. A protein consists of one or more polypeptides coiled into specific confirmations 14. Chaperonins- protein molecules that assist the proper folding of other proteins
