Describe in words how fatty acids are released in the body AND how fatty acids arrive at the appropriate cellular location for use (no structures). Beginning from this point, provide the details in words (names of structures, enzymes, cofactors, etc.) for one round of fatty acid degradation.  Include the tissue and cellular locations for each part of the process of harvesting fatty acids for energy. What pathway does the primary product enter next? Provide details in words (names of structures, enzymes, cofactors, etc.) for the reaction steps where carbon leaves the pathway. You don't have to go over the entire pathway – only the steps where carbon is lost.

A 30 y male was delivered to andrology department for medical evaluation due to ineffective sexual competency. His physical examination and interview with the specialized physician revealed some other symptoms that were related to wounds that won’t heal, unexplained weight loss, hair loss, lack of alertness and sometimes diarrhea. These symptoms were seen in the last 6 months only and nothing seen before.

Semen analysis and other tests were prescribed and the results were:


Semen analysis


Days of abstinence: 3 days

Time of collection: 9:30 am

Time of receipt: 9:45 am

Liquifaction time: 30 min

Volume: 4ml

Viscosity: normal

pH: 8.5

Sperm concentration: 12 million/ml

Sperm motility: marked decreased motility

Morphology: more than 50% normal forms

Spermatids and WBCs: less than 1 million/ml


Other tests


Fructose level was in normal range

Viability testing showed that most sperm are viable

Low serum testosterone

Discuss these results, what is the expected case, mention any confirmatory tests if required
Note : My doctor sad that it was related to zinc deficiency , how i can explain that .
