Protein is one of the nutrients
beside with vitamins, minerals, carbohydrate, fat and water. The source of all
of these nutrients is good. Some foods have much higher amounts of particular
nutrients than others and from time to time we refer to certain foods as
“Protein Foods.” It is necessary to realize that all Foods contain more than
one nutrient and most foods have substantial amounts of a number of nutrients.
For example, meat, which is a good resource of carbohydrate, riboflavin,
protein, fat and calcium? Protein is an necessary
nutrient. There is no life without Proteins. Protein is contained in every part
of our body, blood, the skin, body organs, hair, muscles,eyes, even bone and
Fingernails . Next to water, protein is the most plentiful import in our body.
Proteins are biochemical compound
consisting of one or more polypeptides typically folded into a globular or
fibrous form, facilitating a biological task. It is one of the three major, or
macro, nutrients. Protein is found in
every muscle, cell, and tissue of our body also it is available
in many of the foods that we take everyday.. Basically the protein in
our body is the same as the protein in our food, except that it is structured
differently. Unlike carbohydrates and
fats (the additional two types of macronutrients), Proteins are comprised of
nitrogen-containing groups called amino acids.We know there are 22 kind of
amino acid and the body needs all of them to function properly. Essential amino acids are tryptophan,
methionine,leonine, isoleucine, phenylalanine and histidine. Non-essential
amino acids include asparagine, aspartic acid,alanine and glutamic acid. Conditional amino acids
include glutamine, arginine,
cysteine,proline, glycine, serine, and
tyrosine.
Amino acids are found in animal sources such as meats, milk, fish and eggs, as well as in plant source such as whole grains, pulses, legumes, soy, nuts and seeds. Vegetarians can get enough essential amino acids by eating a variety of plant proteins.People who avoid animal products may practice Proteins combining to get the essential amino acids in their diet
