Essential nutrients
These are the organic compounds present in the food that provide nourishment essential for the development and growth of our body. Nutrients not only provide us with the required energy to carry out various biological processes but are also the building blocks for repair and growth in our bodies.
Vitamins
The vitamins are organic molecules required in low concentration for the proper functioning of the body. They cannot be generated in the organism and are taken into the body through the diet. The lack of proper vitamins results in diverse deficiency disorders. They are thus called essential nutrients. The important vitamins are vitamin A, vitamin B complex, vitamin C, vitamin D, vitamin K, and vitamin E.
Explain the chain of Protein in amino acids linked by peptide bonds.
Protein plays an important role in the structural and functional unit of the body. Proteins are made up of amino acids. Amino acids are organic compounds form from oxygen, hydrogen, carbon, and nitrogen. The human body required 20 different amino acids. These are valine, tryptophan, proline, threonine, tyrosine serine, phenylalanine, lysine, methionine, leucine, isoleucine, histidine, glycine, glutamic acid, cysteine, glutamine, aspartic acid, asparagine, arginine, and alanine.
In peptide bond, there are carbon-nitrogen and all this thing arranged together to make those amino acid structures. Amino acids contain an alpha carbon atom that connected to an amino group, a hydrogen atom, a carboxyl group, and a variable component known as a side chain. The amino acid is linked by a peptide bond where peptide bond made by the biochemical reaction which removes the H2O molecule because it binds the amino group of 1 amino acid to the carboxyl group of neighboring amino acid.
