Proteins are linear polymers formed by linking the a-carboxyl group of one amino acid to the a-amino group of another amino acid. This type of linkage is called a peptide bond or an amide bond. The formation of a dipeptide from two amino acids is accompanied by the loss of a water molecule.
Release date. The Galaxy S8 and S8+ are both available to pre-order from Wednesday 29 March, with early buyers set to receive their handset on 20 April. The smartphones will be available to all from 28 April.
The S8 and S8 Plus only with 64GB of storage, but you do have a choice of three colors: Midnight Black, Orchid Gray and Arctic Silver. The S8 is $750 and S8+ is $850. But carriers like Verizon and U.S. Cellular and the retailer Best Buy offer discounts off that price.
