Amino acid side chains Study guides, Class notes & Summaries

What is the basic structure of an amino acid? What do they look like? (correct answer)amino group (NH2 or NH3), carboxyl group (COO or COOH), alpha carbon (C), and variable group How do you identify the 3 different types of side chains: non-polar/hydrophobic, polar, and charged? (correct answer)Non-polar/hydrophobic - end with CH or "can't have" water. Polar - end with OH, SH, or NH. Charged - end with a charge what kinds of bonds do each of the 3 different types of side chains ma...

Differentiate between complete and incomplete proteins and provide typical sources of each. Complete proteins: Have all nine essential amino acids. Ex. Animal sources of protein (milk, meat) Incomplete proteins: Lack one or more of the essential amino acids. Ex. Plant sources of proteins (legumes) Describe the molecular structure of proteins and the four levels of protein structure. Which bonds are essential to each level of organization? Proteins are composed of long chains of amino acid...
