Reproductive and Metabolic Hormones Certain peptides like kisspeptin analogues act at the hypothalamic level to normalize release of follicle stimulating hormone and luteinizing hormone, indirectly influencing testosterone, estrogen, and ovulation patterns
Rotation Using three coordinates, there is an easy trick to rotate a point by 60 degrees around the origin: rotate the coordinates left, and change all the signs: $$[x, y, z] \rightarrow [-y, -z, -x]$$ (From here its easy to remove the \(z\)-coordinate, as usual, to find: $$[x, y] \rightarrow [-y, x + y]$$ By applying the trick above repeatedly, we can find similar expressions for points rotated by 120, 180, 240, and 300 degrees
For example: Low stomach acid: As we age or due to conditions like acid reflux, the bodys ability to absorb B12 from food or oral supplements diminishes
