Write one function of uric acid​

Antioxidant

Explanation:

Most serum uric acid is freely filtered in kidney glomeruli, and approximately 90% of filtered uric acid is reabsorbed, implying that it has a considerable physiological role [2], [5]. In humans, over half the antioxidant capacity of blood plasma comes from uric acid [5], [6]. Uric acid is a strong reactive oxygen species (ROS) and peroxynitrite scavenger and antioxidant [5], [6], [7], [8]. High levels of uric acid are readily detected in the cytosol of normal human and mammalian cells, especially in the liver [9], vascular endothelial cells, and in human nasal secretions, where it serves as an antioxidant

It forms ions and salts known as urates and acid urates, such as ammonium acid urate.

Explanation:

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
