It covers the canonical 20 amino acids, stereochemistry and chirality at the α carbon, and representations such as Fischer projections. The review also explains amino acids as dipolar ions, acid/base behavior, and key biochemical roles such as nitrogen balance and the urea cycle, glucogenic versus ketogenic metabolism, and transamination. It further introduces protein folding, denaturing, hydrophobic interactions, ligand binding, and amino acid separation and protein purification.","MCAT Amino Acids & Proteins Review Med-Pathway.com The MCAT Experts  \nThe content review is organized into two chapters is organized into two chapters:  \n1. Amino acids/peptides  \n2. Proteins (Including separation techniques)  \nAmino acids, peptides, and proteins are listed in the AAMC Content Guide in BOTH the biological and physical sciences tests. They are commonly emphasized on the MCAT. The following topics will be discussed here. Further topics on protein structure and function can be found throughout the various assessment tests available on our website.  \nChapter 1: Amino Acids/Peptides  \n☐ Structure of canonical 20 amino acids  \n☐ Absolute configuration at the α position and dipolar ions ☐ Acid/Base chemistry and Titration curves  \n☐ Amino acids as precursors  \n☐ Focus on specific Amino acids, including cysteine, glycine, proline, aromatic, glutamine and glutamate, etc.  \n☐ Alanine-glucose cycle  \n☐ Hydrophilic and hydrophobic  \n☐ Amino acid metabolism: glucogenic vs ketogenic ☐ Amino acid transamination  \n☐ Nitrogen balance and the urea cycle ☐ Essential vs. Non essential amino acids ☐ Amino acid synthesis: Strecker and Gabriel  \nChapter 2  \nProtein structure and function  \nProteins  \n☐ 1°, 2° , 3° , 4° structure of proteins including Hemoglobin ☐ Denaturing and folding  \n☐ Hydrophobic interactions  \nMCAT Amino Acids & Proteins Review Med-Pathway.com The MCAT Experts  \nMCAT Amino Acids & Proteins Review Med-Pathway.com The MCAT Experts  \n☐ Hill coefficient and ligand binding (Hemoglobin)☐ Amino acid separation & Protein Purification  \nIntroduction  \nStructure and function: The key paradigm.  \nEnzymes and other proteins fold into their respective three dimensional shapes that dictate consequent cellular function(s) . Numerous pharmaceutical reagents exploit structure/function relationships. In particular, development of specific drugs that bond as agonists (i.e. activators) and antagonists (i.e. inhibitors) has been used in clinical medicine for decades.  \nThe vast majority of pharmaceutical drugs target cellular proteins, ranging from enzyme inhibition to targeting receptors as agonists and antagonists. As proteins are composed of linear chains of amino acids that fold into a functional three dimensional conformation, understanding amino acid structure, particularly in the context of protein function, is a central objective in biochemistry and we know the MCAT loves this topic. Further, amino acids and their derivatives play important roles outside of protein structure and function in diverse processes. This is because many amino acids are turned into important biomolecules ranging from serotonin (neurotransmission) to histamine (allergic response, vasodilation) . It is therefore clear to see why amino acid/protein structure and function formulates a very widely covered  \ncom The MCAT Experts  \nMCAT Amino Acids & Proteins Review Med-Pathway.com The MCAT Experts  \ntopic area on the MCAT.  \nThe primary amino acid sequence of proteins is determined via the mRNA sequence and assembled during ribosomal translation. This is a major theme of Content Category 1B. The chemical diversity of amino acids and their numerous sequence combinations allows for the generation of tertiary folding structures that adopt a plethora of conformations and active sites specifying any number of functions. The canonical 20 amino acids are presented below.  \nAbsolute configuration at the α carbon  \nEach of twenty canonical amino acids, with the exception of glycine, is chiral. The structures are shown. Chirality, or handedness, is an important aspect of biology and chemistry. It is the subject of the “Principles of Stereochemistry”learning/testing module. Stereochemistry is presented in the Chemical and Physical Foundations of Biological Systems in Section 5B of the AAMC MCAT outline.  \nWith the exception of glycine, each of the amino acids incorporated into proteins displays optical activity.
