Study Notes
Biochemistry Study Notes
Amino Acid Biochemistry
- The protein portion of an enzyme is called apoenzyme (Q6)
- Arginine's R group has a guanidine group (Q2)
- The correct primary EC number of the enzyme serum glutamate pyruvate transaminase is 2 (Q9)
Carbohydrate Biochemistry
- Glucose oxidation at the first carbon yields gluconic acid (Q17)
- Sucrose is a disaccharide consisting of glucose and fructose (Q14)
- Specific test for galactose is the mucic acid test (Q18)
Lipid Biochemistry
- Saturated fatty acid with 18 C is stearic acid (Q20)
- Lecithin, a major component of cell membranes, is phosphatidylcholine (Q23)
- Esters of long-chain fatty acids with long-chain monohydric alcohols are waxes (Q24)
Nucleic Acid Biochemistry
- The composition of a nucleoside is base + sugar (Q28)
- The direction of genetic information flow during gene expression is DNA → RNA → Protein (Q32)
- In prokaryotes, the ribosomal binding site on the mRNA is called the Shine-Dalgarno sequence (Q42)
Metabolic Pathways
- Glycolysis is a catabolic process that results in the production of ATP and NADH (Q47)
- The citric acid cycle (Krebs cycle) is a series of reactions that produce ATP, NADH, and FADH2 (Q51)
- The electron transport chain is a series of protein complexes that generate ATP from the energy released from NADH and FADH2 (Q52)
Other Topics
- Isoleucine has a pI of 6.02 (Q1)
- Vitamins and their functions:
- Vitamin B7 is needed by the enzyme acetyl CoA carboxylase, which catalyzes the carboxylation of acetyl CoA to malonyl CoA (Q7)
- Vitamin K is necessary for the synthesis of certain clotting factors (Q25)### Metabolic Disorders and Enzymes
- Phenylketonuria is related to phenylalanine.
- Albinism is related to tryptophan.
- MSUD (Maple Syrup Urine Disease) is related to isoleucine, leucine, and alanine.
Cellular Pathways and Enzymes
- The urea cycle does not occur inside the mitochondrion, nor within the mitochondrial membranes.
- The citric acid cycle, beta-oxidation, and oxidative phosphorylation occur inside the mitochondrion, or within the mitochondrial membranes.
- Glycolysis does not occur inside the mitochondrion, nor within the mitochondrial membranes.
- Pyruvate carboxylase catalyzes the reaction: Pyruvate → OAA.
- Pyruvate dehydrogenase complex is not responsible for the reaction: Pyruvate → OAA.
- A deficiency in Pyruvate dehydrogenase can cause lactic acidosis due to pyruvate being shifted towards anaerobic respiration instead of being utilized for the Krebs' cycle.
