Importance of Proteins
The human body comprising majorly of water has around 40% of dry matter consisting of various nutrients such as Protein, fat, carbohydrate and minerals.
If we Dig deep down further, we get to know that out of total dry matter proteins make up about 40% of it. Proteins are such an important nutrient of our body, that losing about even 1/6th of it can cause serious illness to the body.
But considering the importance of proteins to the body for muscle development is just the tip of the iceberg. Proteins play very important and pivotal roles in many systems of our body and are largely responsible for the structure of the body tissues.
– Proteins as very commonly known make up the bulk of the muscles, but they are also a significant part of bones, liver, intestine, kidneys, hair, and nails, etc. creating the structural framework of the body.
– As antibodies and interleukins proteins help to defend the body against diseases and infections. This is done by aiding responses that protect the body against foreign and invading substances.
– Proteins such as myosin and actin help in the contraction. So, they help in the movement of the body by allowing shortening of the muscle cells.
– By acting as specific enzymes (e.g. salivary amylase, Sucrase, etc.), proteins speed up the umpteen number of reactions occurring in various cells of our body.
– Haemoglobin, a protein present in red blood cells of blood carries oxygen throughout the body. It also brings back toxic carbon dioxide to the lungs for expulsion.
– Rhodopsin, a photopigment located in the retina of the eyes is a protein containing a compound that helps in night vision.
