Proteins are formed by joining the-CO 2 H end of one amino acid with the-NH 2 end of another to form an amide.
Plant proteins are formed in the protein synthesis, a series of bio-chemical reactions where: 1) Parts of the plant's DNA is split up, copied into RNA and cut away (DN … A is restored to its original shape after). Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid. The linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries. The largest group of amino acids have nonpolar side chains. The chemistry of amino acid side chains is critical to protein structure because these side chains can bond with one another to hold a length of protein in a certain shape or conformation. Charged amino acid side chains can form ionic bonds, and polar amino acids are capable of forming hydrogen bonds. Proteins are formed by the different combinations of amino acids. There are twenty type of amino acids (different from each other due to variable group R). DNA molecules form amino acids. Amino acids are bonded together by  peptide bonds. This chain on amino acids and peptide bonds form the  structure for protein. These proteins are created in the body by condensation of amino acids under the influence of enzyme catalysts, using patterns or direction from the nucleic acids in the cells. The amino acid units in a protein molecule are held together by peptide bonds, and form chains called polypeptide chains. The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain (see below). Proteins are formed by joining the-CO 2 H end of one amino acid with the-NH 2 end of another to form an amide. The-CONH-bond between amino acids is known as a peptide bond because relatively short polymers of amino acids are known as peptides.
