I have a project at hand, the topic being vitamins and hormones.
While reading about Vitamin K on pubchem, I found that ##K_1## is the compound phytonadione, while my biology book mentions it to be phylloquinone. Similarly, ##K_2## is the compound menaquinone-2 as per pubchem, the the book says it's farnoquinone.
Now it turns out that phytonadione and phylloquinone are actually isomers, and the same is the case with menaquinone-2 and farnoquinone.
Can anyone confirm which is correct? Pubchem seems trustworthy, and so is the book.
