Unformatted text preview: Biochemistry- 2 Proteins Structure Function Nucleic acids Definition Nitrogenous bases Aldopentoses Nucleic acids DNA structure RNA structure Function Lipids Definition Fats Function Proteins Structure Each type of protein molecule in its natural environment folds into a unique 3D structure called the native conformation defined by primary, secondary, tertiary and perhaps quaternary levels of organization. The most important determinant of protein structure is the influence of the amino acid sequence (primary structure ). Secondary structure : Regular, repeating structural elements that are close together in the linear sequence of the protein. The most common are alpha helices and beta sheets. Tertiary structure : Complete three dimensional arrangement in space. Quaternary structure : Association of two or more polypeptide chains to form a multisubunit protein molecule. Myoglobin Ricin Hemoglobin -Helix: it is a rod-like structure formed by a tightly coiled polypeptide backbone. -Sheet: Is composed of fully extended polypeptide chains linked together through hydrogen bonding between adjacent strands of the sheet.hydrogen bonding between adjacent strands of the sheet....
