Detailed explanation-1: -The ‘ground substance’ of extracellular matrix is an amorphous gelatinous material. It is transparent, colourless, and fills the spaces between fibres and cells. It actually consists of large molecules called glycosoaminoglycans (GAGs) which link together to form even larger molecules called proteoglycans.
Detailed explanation-2: -Connective tissue, also called extracellular matrix, is composed of two types of large biomolecules: proteoglycans and fibrous proteins such as collagen, laminin, fibronectin and elastin.
Detailed explanation-3: -The extracellular matrix of connective tissue is composed of fibers and ground substance. In ordinary connective tissue, the principal fiber type is collagen (the most abundant protein in the body), with elastic fibers as a minor element; ground substance consists mainly of water.
