Polysaccharides are of two main types.
1. Homopolysaccharides
2. Heteropolysaccharides
Heteropolysaccharides are further classified as:
a) GlycosAminoGlycans (GAGs)
b) Glycoconjugates
c) Mucilages
Proteoglycan is a type of glycoconjugates whereas heparan sulfate, dermatan sulfate and hyaluronic acid are examples of GAGs.

Glycoproteins and proteoglycans are combinations of proteins and?
Glycoproteins are combinations of proteins and carbohydrates, where carbohydrates are attached to the protein backbone. Proteoglycans, on the other hand, are combinations of proteins and glycosaminoglycans (GAGs), which are long, linear chains of repeating disaccharide units. Both glycoproteins and proteoglycans are important components of the extracellular matrix in tissues and play essential roles in cell signaling, adhesion, and structure.
What mineral is found in cartilage?
Collagen is the primary protein found in cartilage, which provides structure and support to the tissue. Other minerals found in cartilage include water, glycosaminoglycans, and proteoglycans. Minerals like calcium, magnesium, and phosphorus can also be present in trace amounts.
What keeps cartilage slippery?
because it needs to be able to reduce friction between bones
Which part of the matrix retains water?
The extracellular matrix, specifically the ground substance, retains water due to the presence of glycosaminoglycans like hyaluronic acid and proteoglycans. These molecules have a high water-binding capacity, providing hydration and lubrication to tissues.
The ground substance that helps lubricate joints and bind cells together is?
The ground substance that helps lubricate joints and bind cells together is called extracellular matrix. It is made up of glycosaminoglycans, proteoglycans, and other molecules that provide structural support and facilitate cell communication within tissues.
Are proteoglycans organic or inorganic?
Proteoglycans are organic molecules. They are composed of proteins and long chains of complex carbohydrates called glycosaminoglycans.
What is the difference between a glycoprotein and a proteoglycan?
Actually, proteoglycans are conjugates of proteins and carbohydrates in which there is more carb and less protein. In fact, proteoglycans have GAGs (heteropolysaccharides) as carbohydrates. Glycoproteins, on the other hand, have more protein and less carb. Here, carbohydrates are in the form of Oligosaccharides.
Glycoproteins and proteoglycans are combinations of proteins and?
Glycoproteins are combinations of proteins and carbohydrates, where carbohydrates are attached to the protein backbone. Proteoglycans, on the other hand, are combinations of proteins and glycosaminoglycans (GAGs), which are long, linear chains of repeating disaccharide units. Both glycoproteins and proteoglycans are important components of the extracellular matrix in tissues and play essential roles in cell signaling, adhesion, and structure.
An extracellular ground substance is characteristics of?
An extracellular ground substance is characteristic of connective tissues. It provides support and maintains the structural integrity of the tissue by filling the space between cells and fibers. The ground substance is composed of water, glycosaminoglycans, proteoglycans, and glycoproteins.
What mineral is found in cartilage?
Collagen is the primary protein found in cartilage, which provides structure and support to the tissue. Other minerals found in cartilage include water, glycosaminoglycans, and proteoglycans. Minerals like calcium, magnesium, and phosphorus can also be present in trace amounts.
What negatively charge are glycosaminoglycans?
Glycosaminoglycans are negatively charged due to the presence of sulfate and carboxyl groups in their structure. These groups can ionize in aqueous solutions, contributing to the overall negative charge of glycosaminoglycans.
Most of the volume in loose connective tissue is made up of?
Most of the volume in loose connective tissue is made up of ground substance, which is a gel-like material composed of water, glycosaminoglycans, proteoglycans, and glycoproteins. This ground substance provides support and a medium for the movement of nutrients and waste products in the tissue.

Which part of the matrix retains water?
The extracellular matrix, specifically the ground substance, retains water due to the presence of glycosaminoglycans like hyaluronic acid and proteoglycans. These molecules have a high water-binding capacity, providing hydration and lubrication to tissues.
What is unbounded water?
hydrated proteoglycans
What is composed of glycoproteins and water-binding glycosaminoglycans?
macrophages
Are glycosaminoglycans positive or negative?
Negatively charged polysaccharides
