Secondary structure of protein

Proteins are an important class of molecules found in all living cells. A protein is composed of one or more long chains of amino acids , ...

Fluorescence has two distinct stages, excitation stage and emission stage. It is a phenomenon where fluorescent chromophore absorbs a light photon, typically remains in an excited state for a few nanoseconds and then emits a lower energy photon. Both the efficiency of light absorption (ε) and the efficiency of photon emission from an excited fluorophore (Q) determine the intensity of a sample. Changes in either ε and/or Q will lead to changes in sample emission intensity.

4 classes of protein structure • Primary • Secondary • Tertiary • QuaternaryKEY PROTEIN FUNCTIONS • Accelerate reactions • Provide structural support • Send communication signals • Aid in cellular movement • Provide immune defense • Storage of nutrients (nitrogen) "Structure determines function."CLASSES OF PROTEIN STRUCTURE 1. Primary protein structure • Together, peptide bonds and amino acids form a polypeptide chain (aka a protein). • The primary structure of a protein determines its…

Primary, Secondary, Tertiary and Quaternary structure

alpha helices and beta pleated sheets are the secondary structure of polypeptides. Each occurs as a result of various arrangements of hydrogen bonds between the residues contained therein. To be sure, alpha helices are twisted and beta pleated sheets are two sheets of the polypeptide chain from it bending once at the top and interacting.

Protein structure is determined by amino acid sequences. Learn about the four types of protein structures: primary, secondary, tertiary, and quaternary.

The sequence and number of amino acids in a polypeptide is the primary structure AND The secondary structure is the formation of α-helices and β-pleated sheets stabilised by hydrogen bonding AND The tertiary structure is the further folding of the polypeptide stabilised by interactions between R groups AND The quaternary structure exists in proteins with more than one polypeptide chain
