The test results showed sheep skin gelatin value that is pH 3,52 - 3,85 and protein 88,80 - 90,47%. HCl 2% ability to hydrolyze sheep skin collagen is better than 2% H2SO4. Highest pH and protein values occur at 4 hours of soaking time.
5/7/2020· Studies have shown that an increase in arachidonic acid raises the anaerobic capacity and causes the muscle fibers to thicken as a result of greater protein synthesis (1, 2). Bodybuilders use arachidonic acid supplements in order to induce inflammation in their muscle tissues, forcing their muscles to grow in greater size and shape.
