THE BIG BAD STEROID PROFILE

All fungi-yeast,plant,animal and human sterols share the same nuclearstructure 19 carbons.Well nearly all.
Different Sterols, different side chain lengths as seen in the numberof carbons in that side chain. Human-animal 8 carbons. Fungi-yeast 9 carbons(with exceptions I think). Plant 10 carbons (exceptions).

The catch, Animals-Humans and Fungi-yeast share the 7-dehydrosterol( double bond conjugation ) intermediate characteristic as in ERGOSTEROL(provitaminD-2) and 7-DEHYDROCHOLESTEROL(Provitamin D-3).

Just one second here, do fungi and yeast have some type of calcium metabolism? They must have a requirement for Calcium as a nutrient.
Anyone make their own wine ? Maybe a clue here.

Reference will be to Fungi.
The end sterol for those little buggers is an energy reactive 7-dehdrosterol.....ERGOSTEROL. In animals and humans it is a secondary pathway,intermediate sterol .....7-DEHYDROCHOLESTEROL that goes to VITAMIND-3 if activated by a higher energy source. ie: ULTRA-VIOLET ( A,BandC) is at the top end of the visual electromagnetic spectrum.GAMMAIrradition energy is 300,000 times greater thanthat of ULTRA-VIOLET LIGHT.
Instead of being activated by HIGHER ENERGY, the second doublebond of 7-DEHYDROCHOLESTEROL can be reduced to a single carbon bond by a reductase enzyme reaction to bring the reactive sterol back to CHOLESTEROL ( theory ).
So, Fungi need to be in an environment that is damp but not necessarilymoisture ( organic liquids ) . They require CHONy substrates of plant,animal and human origin or manufacture. ie:oils of the skin, aviation fuel.
They do not like light. Some fungi have light absorbingpigments in their cells to offer protection for these organisms in exposureto sunlight ie Claviceps Purpurea ?? Hey, ....something like the ULTRA-VIOLETlight absorbing chemicals found in paints and plastics.
So, they like darkness....mushrooms like darkness. Anyone ever go pickingPine Mushrooms ?

VITAMIN D-2 is not preformed in nature except for certain mushrooms??

What happens to ERGOSTEROL and VITAMIN D-2 when too muchenergy strikes these substances. Like ALPHA, BETA and GAMMA IRRADIATIONenergies.

I f you are a wrench and work on your automobile, you probably haveused a thread or bearing retaining product.
They all have mold-fungi like smells.......

To be continued were no fungi dare to tread.... I think
