PPT-Structure of Protein-II SECONDARY STRUCTURE

Localized arrangement of adjacent amino acids formed as the polypeptide chain folds The regions of ordered structures formed by interaction of hydrogen bond donor and hydrogen bond acceptor residues of the repeating peptide unit. Why do we want to know protein structure?. Classification. Functional Prediction. What is protein structure?. Primary - chains of amino acids. Secondary - interaction between groups of amino acids. Tertiary - the organization in three dimensions of all the atoms in a polypeptide. Gustavo Caetano - . Anolles. 1. PowerPoint by Casey . Hanson. Protein Sequence, Structure, and Function | Gustavo Caetano - Anolles | 2015. Exercise. In this exercise we will be doing the following:. Sequence:. Edman degradation. Mass spectrometry. Secondary structure:. Circular Dichroism. FTIR. Tertiary, quaternary structure:. NMR. X-ray crystallography. Protein sequencing approaches depend on what is known and what is the goal. 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.

It contains nitrogen and is responsible for the formation, maintenance, and repair of the body’s tissues/ It can also be used for energy. CHNO. Amino acids . In a day and age where people have busier lifestyles, where obesity is becoming a trend, and homes becoming smaller – manufacturers have created an empire surrounding quick and easy meals, snacks, and even drinks. More people prefer instant gratification, which led to wanting things done in an instant – instant messaging, instant coffee, instant noodles, and even instant meals! Proteins are major components of all cellular systems. Proteins consist of one or more linear polymers called polypeptides. Proteins are linear and never branched.

It has aptly been described as the second half of the genetic code, and as the three-dimensional code, as opposed to the one-dimensional code involved in nucleotide/amino acid sequence. .
