Hello students and welcome back with another video.

The question we have is the polysepariser formed the hard outer covering of many invertebrates is collagen, chyton, chyton, chyton, chyton, chytoes, right? so, you know, the polysaccharides that form the hard outer covering of many invertebrates is chyton, right? so chemically, chyten is a nitrogen container.
00:31
Polysaccharide it protects the bodies of many insects such as grasshoppers and beetles also invertebrates such as shrimps or shellfish so this covering provides also structural support to the bodies of these animals and is called therefore their exoskeletons option p is correct over here right okay so collagen is one of the protein components of extracellular matrix which is easy and red provides strength to many tissues such as skin, cartilage, and bones.
01:06
However, collagen is not the building substance for exoskeletaline present in many invertebrates.
01:12
So option a is not correct over here, right? then chondritin sulfate are glyco -samenoglycans, you know, which is gag that contains a side chain of chondroit and sulfate.
01:26
Gags are negatively charged and are thus able to attract cations and water to ecm...
