Vitamin D is synthesized when modified cholesterol molecules in the skin are irradiated by ultraviolet B (UVB) light from the sun. This process begins when UVB rays convert 7-dehydrocholesterol in the skin into previtamin D3, which is then transformed into active vitamin D through further processes in the liver and kidneys. Adequate exposure to sunlight is essential for maintaining optimal vitamin D levels in the body.

Where are all steroid hormones derived from?

Steroid hormones are derived from cholesterol, which is a type of fat molecule. Cholesterol is modified and converted into different steroid hormones by various enzymes and processes in the body. These hormones play crucial roles in regulating various physiological processes in the body.


Where are cell products chemically modified and stored?

Every cell has a a cell membrane and only water, oxygen, and CO2 can pass through it. The protein doorways help bring in large molecules. Waste products get sent out by the vesicles (which have there own membrane). Cells have organelles which are tiny organs in the cells. So basically the cell products are protected by the cell membrane which is made of layers of linked molecules.


Which molecules are processed by the rough endoplasmic reticulum (ER)?

Proteins are the main molecules processed by the rough endoplasmic reticulum (ER). The ribosomes on the rough ER synthesize proteins, which are then folded and modified as they pass through the ER. Additionally, some lipids are also synthesized and processed in the ER.

What type of modification was made for agomir/ antagomir?

The Chemically-modified Construction of Antagomir and Agomir: Antogimir: 3' terminal was modified by cholesterol, there are two thiols modification in the 5' terminal, four thiols modification in the 3' terminal, and the whole strand is modified by 2'-OMe. Agomir: in the antisense strand, 3' terminal was modified by cholesterol, there are two thiols modification in the 5' terminal, four thiols modification in the 3'terminal, and the whole strand is modified by OMe.

How is synthetic testosterone produced?

Synthetic testosterone is produced through a chemical process that involves modifying the molecular structure of cholesterol. This modified cholesterol is then converted into testosterone through a series of chemical reactions in a laboratory setting.
