Excellent coffee should be made fresh from freshly roasted coffee beans, so try to find a cafe or market that roasts their beans daily, or make your own coffee from freshly roasted beans. For top quality espresso, seek out a cafe that uses the finest espresso machine and employs a skilled barista.
Hyaluronic acid, one of the polymers that accounts for the toughness and flexibility of cartilage and tendon, typiiies this group of extracellular polysaccharides. Other heteropolysaccharides, sometimes in very large aggregates with proteins (proteoglycans), account for the high viscosity and lubricating properties of some extracellular secretions.
There are three varieties of cartilage, hyaline, elastic, and fibrocartilage. The most abundant type is hyaline, found as supportive tissues in the nose, ears, trachea, larynx, and smaller respiratory tubes. As articular cartilage, hyaline is found covering the articular surfaces of bones in synovial joints.Here, hyaline cartilage reduces friction and acts as shock-absorbing tissue. to the left of the stacks of chondrocytes, the extracellular matrix of hyaline cartilage is very uniform in appearance in contrast to that of bone. 2  cartilage typically appears blue or light purple because extracellular components of the matrix attract basic stains.
