The fatty acid is used by various tissue like muscles, heart, kidney and liver for energy source, while glycerol is stored in the adipose tissue. Fat of dogs, rats, cats and pork have saturated fatty acid on position 2. If a person eats the fat of a herbivorous animal, the fat will be hydrolyzed, absorbed, and then resynthesized and stored as human fat, while that of carnivorous fat will not be hydrolyzed and therefore has to be deposited in humans as pork fat in the adipose tissue. Circulating hormones are in bound form and free form. The free form has to be attached to the receptor in fat tissue before becoming active.
Obesity decreases the number of receptors.
Therefore hormones cannot utilize them. The amount of fat also controls hormone release. Therefore we see menarche is delayed in athletic girls with less fat, and occurs early in sedentary overweight girls. It can be postulated that in humans who have pork human fat deposit, there is derangement in the binding of hormones. Therefore they have higher levels of circulating active hormones.
