Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
Because of the helix dipole, the phosphate ions are likely to bind to
The side-chains of a-helix
The C-terminus of a-helix
The N-terminus of a-helix
The carbonyl group of the peptide bond
Function of a protein depends on it's three dimensional structure and structure of the protein can be described by structural features grouped into 4 different levels: primary, secondary, tertiary and quaternary structure
Two types of secondary structures are abundant in protein: alpha helix and beta sheets.
The alpha helix is formed by the formation of a hydrogen bond between, the carbonyl oxygen (of the peptide bond between the first and second residue) and amino hydrogen (of the peptide bond between the fourth and fifth residue).
