PROTEINS
Function:
- Protein has different functions. The enzymatic proteins for example can accelerate the
chemical reaction, the defensive proteins protect the body against diseases, or the storage
and transport protein who transport and store proteins
- Most enzymes are proteins, and life wouldn’t be possible without enzymes.
ENzymatic proteins regulate metabolism by acting as catalysts, or chemical agents that speed
up chemical reactions without being consumed in them.
- The enzymes keep the cells running by carrying out the process of life.
Structure:
- The structure of a protein is very sophisticated. It has many levels and molecules that make
up a full protein.
- Proteins are made of 20 amino acids linked together by covalent bonds named peptide
bonds. Then a polymer of amino acids is called a polypeptide. The order is amino acids,
polypeptides, proteins
- The amino acids are made from an amino group, a carboxyl group, a hydrogen atom, and a
variable group (R). And at the center of the amino acids is the alpha carbon,
- The R group or side chain is different with each amino acid. There are nonpolar, polar, and
electrically charged side chains.
- Proteins share three superimposed levels of structure. A fourth level arises when a protein
consists of two or more polypeptide chains.
- The primary structure is its sequence of amino acids and its determined by the inherited
genetic information. It is like a linear chain.
Secondary structures are the segments of the polypeptide chains repeatedly folded or coiled
in patterns. These are the result of hydrogen bonds.
The tertiary structure is the overall shape of a polypeptide that results from an interaction
between the side chains or R groups of the various amino acids.
- Lastly, protein structure may change depending on the environment they are exposed to. So if
the PH of salt concentration is not on the desired level; they will eventually change and
decompose.
