1 The hypothalamus, pituitary gland, and the gonads (ovaries, testicles) operate in a feedback loop, producing and maintaining the levels of sex hormones (androgens and estrogens) that are mainly responsible for the primary and secondary changes of puberty.
Calculation: Here is the formula for FIP: FIP = ((13*HR)+(3*(BB+HBP))-(2*K))/IP + constant. The constant is solely to bring FIP onto an ERA scale and is generally around 3.10. You can find historical FIP constant values here, or you can derive the constant yourself.
1 FIP unit of Bromelain is the amount of enzyme that hydrolyzes casein under the standard conditions into not acid-precipitable peptides at an initial rate such that there is liberated per minute an amount of peptides which gives the same absorbance at 275 nm as 1 Â°mole tyrosine.
