All of the proteins on the face of the earth are made up of the same 20 amino acids. Linked together in long chains called polypeptides, amino acids are the building blocks for the vast assortment of proteins found in all living cells.When two amino acids are chemically joined together, the resulting structure is called a ____. a. dipeptide b. diglyceride c. polypeptide d. disaccharide e. polysaccharide. a. 11. Which of the following is a feature of hemoglobin? a. It has no tertiary structure. b. It holds the mineral calcium. c. It is constructed of four polypeptide chains.When two amino acids are chemically joined together, the resulting structure is called a ____. dipeptide. What is the primary factor that differentiates one amino acid from another?the four atoms, nitrogen, hydrogen, carbon and oxygen that link the two amino acids together is called a peptide bond. two amino acids linked together in his way is called a dipeptideand a long chain of amino acids is called a polypeptide. Polypeptides and Amino acid sequencesA Dipeptide is two amino acids joined by a peptide bond.

More amino acids need to join up until you have a chain of amino acids joined together by peptide bonds, which gives us a polypeptide. Polypeptides are important to the body and can be found inThe resulting amino acids are joined together through dehydration synthesis, a process in which a peptide bond is formed between the amino acids. A polypeptide chain is formed when a number of amino acids are linked together by peptide bonds. After several modifications, the polypeptide chain becomes a fully functioning protein.When two amino acids are chemically joined together, the resulting structure is called a a. dipeptide. b. diglyceride. c. polypeptide. d. disaccharide. b. 16. What is the composition of a tripeptide? a. One amino acid with three carbons b. Three amino acids bonded togetherPrimary Structure describes the unique order in which amino acids are linked together to form a protein. Proteins are constructed from a set of 20 amino acids. Generally, amino acids have the following structural properties: A carbon (the alpha carbon) bonded to the four groups below: A hydrogen atom (H) A Carboxyl group (-COOH) An Amino group

When two amino acids are chemically joined together, the resulting structure is called a ____. dipeptide diglyceride polypeptide disaccharide polysaccharide. dipeptide. In general, the protein quality in grains would be most improved by the addition of a plant protein rich in ____.When two amino acids are chemically joined together, the resulting structure is called a ____. A structure upon which proteins are assembled. What is a ribosome? sickle-cell anemia. A common genetic variation which causes a change in the amino acid sequence in the structure of hemoglobin leads to the disease ____.They are a sophisticated, diverse group of molecules, and yet they are all polymers of just 20 amino acids. Amino acids have a carbon attached to a hydrogen, an amino group, a carboxyl group and something else (R). Its the something else that give the amino acid its characteristics (3.12a&b, pg 42). Amino acids are joined together by peptideIn the dehydration synthesis reaction between two amino acids, with are ionized in aqueous environments like the cell, an oxygen from the first amino acid is combined with two hydrogens from the second amino acid, creating a covalent bond that links the two monomers together to form a dipeptide. In the process a water molecule is formed.Proteins range in size from 50 amino acids in length to the largest known protein containing 33,423 amino acids. Macromolecules with fewer than 50 amino acids are known as peptides. Figure 11.4 Peptides and Proteins are macromolecules built from long chains of amino acids joined together through amide linkages.
