BCAAs. Next up: BCAAs. BCAA stands for Branched-Chain Amino Acids. Amino acids are the building blocks of protein: the point of BCAAs is that instead of eating the protein and then having to break it down yourself, you can just skip straight to the broken-down form.
To answer your question about HBSag: it is Hepatitis B surface antigen. This tests for the presence of virus.

Infected people can pass the virus on to others through their blood and infected bodily fluids. as far as for hepatitis B surface antibody (HBsAb or anti-HBs).
Rating Newest Oldest. Best Answer: Alkali metals are reactive because of their ionization energies. Ionization energy is the energy required to remove one electron from the atom. Alkali metals have only one valence electron, and if you'll recall all atoms want to be noble gases, i.e. they want full valence shells.ating Newest Oldest.
