Name the following structures. (pts) HO OH NH3 NH2 HO-P-O-P-OH<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The Correct Answer and Explanation is:<\/strong><\/p>\n\n\n\n

Here are the correct names for the structures shown in the image:<\/p>\n\n\n\n

a.<\/strong> Citric acid<\/strong>
b.<\/strong> Glutamic acid (in its zwitterionic form)<\/strong>
c.<\/strong> Adenosine triphosphate (ATP)<\/strong><\/p>\n\n\n\n

\n\n\n\n

Explanation:<\/h3>\n\n\n\n

a. Citric acid:<\/strong>
This molecule has three carboxylic acid groups (\u2013COOH) and one hydroxyl group (\u2013OH) attached to a central carbon chain. It is a tricarboxylic acid commonly found in the citric acid cycle (Krebs cycle), crucial for energy production in aerobic organisms. Its structure consists of a six-carbon backbone with three carboxylic acid groups, making it a triprotic acid.<\/p>\n\n\n\n

b. Glutamic acid (zwitterion):<\/strong>
This is an amino acid structure. It features two carboxyl groups (\u2013COO\u207b at physiological pH) and one amine group (\u2013NH\u2083\u207a). The side chain is a \u2013CH\u2082CH\u2082COO\u207b group, characteristic of glutamic acid. The structure shown here is a zwitterion: a molecule with both positive and negative charges but overall neutral. This form is typical at physiological pH (~7.4). The central carbon is chiral, with an L-configuration in biological systems.<\/p>\n\n\n\n

c. Adenosine triphosphate (ATP):<\/strong>
This molecule is the primary energy currency of the cell. It consists of:<\/p>\n\n\n\n

    \n
  • An adenine<\/strong> base (a purine),<\/li>\n\n\n\n
  • A ribose<\/strong> sugar (a five-membered ring with hydroxyl groups),<\/li>\n\n\n\n
  • Three phosphate<\/strong> groups connected in sequence.<\/li>\n<\/ul>\n\n\n\n

    ATP stores energy in the high-energy phosphate bonds, particularly between the second and third phosphate groups. When hydrolyzed (ATP \u2192 ADP + Pi), energy is released for cellular processes like muscle contraction, active transport, and biosynthesis.<\/p>\n\n\n\n

    Understanding the structures of these molecules is essential in biochemistry. Citric acid is part of the Krebs cycle; glutamic acid is a key neurotransmitter and precursor to GABA; ATP drives nearly all biochemical reactions requiring energy.<\/p>\n\n\n\n
