Protein and Amino Acids. Introduction. Protein is a major component of most body tissues including:. Muscle. Bone. Cartilage. Tendons and Ligaments. Hair and Hooves. Enzymes, hormones, and antibodies. Grant . Alex . Curtis. Why?. The purpose of this study was to examine the net hormonal effect of amino acid supplementation on the overreaching resistance training-induced hormonal stress response.. Variables. Formation of Aminoacyl tRNAs. Ribosome structure. Stages of Translation. Relationship between DNA, mRNA, and Protein Sequences. Translation and the Genetic Code. Amino acid structure. Four different groups are attached to the central carbon atom (. Chapter 30, . Stryer. Short Course. Overview. Amino Acid Catabolism. Nitrogen removal. Urea Cycle. Metabolism of carbon backbone.

Proteins are linear and never branched. Different AA’s are linked together via . Peptide bond formation. : . α-carboxyl group of one amino acid (with side chain R1) forms a covalent peptide bond with α-amino group of another amino acid . ( . with the side chain R2) by removal of a molecule of water. The result is : Dipeptide ( i.e. Two amino acids linked by one peptide bond). By the same way, the dipeptide can then forms a second peptide bond with a third amino acid (with side chain R3) to give . Overview. In this lecture we will discuss:. The role of protein in the body.
