Biochemistry II Exam 4 Chapter 24 Lipid Biosynthesis What is the difference between fatty acid synthesis and fatty acid degradation? ● Use of CoA and acyl protetin: Intermediates in synthesi s are linked to -SH groups of acyl carrier proteins like phosphopantetheine and cysteine(as compared to -SH groups of CoA in breakdown) ● Cellular compartment: Synthesis in cytosol; breakdown in mitochondrial matrix ● Enzymes of fatty acid synthesis are components of one long polypeptide chain, the fat...

BIOL/CHEM 3362 - BIOCHEMISTRY II EXAM 3 STUDY GUIDE 1. How are the chiral carbons on the glycerol of the trigycerides determined? C1 is the carbon that would lead to S-configuration if its priority was increased. (chapter 8 slide 44) 2. How are the archaeal membrane lipids different from membrane lipids found in bacteria and eukaryotes? They are connected to the enantiomers of the bacteria and eukaryotes glycerol. (chapter 8 slide 49-50), Archaea vs bacteria:snG1P vs snG3P (enantiomers). Bacteri...

Study guide test 2 Strategies of nucleotide synthesis: precursors, when is ribose added, how is ribose activated and added, what are first purines and pyrimidines made, how are the various forms of THF made and/or interconverted, regulation of purine synthesis (where are committed steps), how is a balance between AMP and GMP achieved, how do folic acid antagonists impair purine synthesis. • Pyrimidines: base is made before adding the ribose sugar • Purines: ribose is already present  suga...

STUDY GUIDE TEST 1 CHAPTER 21: PHOTOSYNTHESIS Where does photosynthesis occurs in plants and bacteria? • Plants- chloroplasts o Light reactions in the thylakoid membrane o Dark reactions in the stroma • Bacteria- o Cyanobacteria- thylakoid membranes in cytoplasm o Photosynthetic bacteria- in membranes in the cytoplasm Chloroplasts structure and function are very important. Inner membranes are important for photosynthesis to occur because of the separation of charges. Outer membrane - It is a...

BIOL 3362 - Exam 2 Study Guide/BIOL 3362 - Exam 2 Study Guide. Chapter 26: Nucleotide and Pidgeon Metabolism Nucleotides are energy currency- and are used to energize a variety of cellular processes Uridine nucleotides- activates carbohydrates Cytosine nucleotides- activates phospholipids Guanine nucleotides- activate steps of protein synthesis Many coenzymes are nucleotide derivatives Nucleotides control key enzymes of metabolism (makes sense since metabolism creates energy) Cy...

BIOL 3362 - Exam 3 Study Guide/BIOL 3362 - Exam 3 Study Guide. Chapter 8 – Lipids • How the fatty acids are denoted according to IUPAC nomenclature rules? The longest carbon chain in the molecule determines the prefix. Since the highest priority functional group of fatty acids is the carboxyl group, the suffix is –oic acid. Example: A 12-carbon, fully saturated fatty acid is called dodecanoic acid. In the case of unsaturated fatty acids, an –cen- is added. Example: A 16-carbo...

Acetyl-CoA carboxylase (ACC) makes malonyl-CoA (activated 2 carbon donor) from acetyl-CoA using carboxylation (acetyl units activated through carboxylation). ○ Overall reaction is spontaneous. ○ ATP dependent ○ Committed step (irreversible!!) / rate limiting
