Dermatan sulfates function in the skin, tendons, blood vessels, and heart valves. [19] Hyaluronic acid Hyaluronic acid is a major component of synovial tissues and fluid, as well as the ground substance of other connective tissues. Hyaluronic acid binds cells together, lubricates joints, and helps maintain the shape of the eyeballs. [19]
Amino acid 2.7-5.5 × 10 −5: 2.4 ... Needed for nerve cells, red blood cells, and to make DNA ... the fractions of Whole Blood used for transfusion are also called ...
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
The main intravascular fluid in mammals is blood, a complex mixture with elements of a suspension (blood cells), colloid , and solutes (glucose and ions). The blood represents both the intracellular compartment (the fluid inside the blood cells) and the extracellular compartment (the blood plasma). The average volume of plasma in the average ...
Important GAGs found in ground substance include hyaluronic acid, heparan sulfate, dermatan sulfate, and chondroitin sulfate. With the exception of hyaluronic acid, GAGs are bound to proteins called proteoglycans. Glycoproteins are proteins that attach components of the ground substance to one another and to the surfaces of cells. [3]
The formed elements are the two types of blood cell or corpuscle – the red blood cells, (erythrocytes) and white blood cells (leukocytes), and the cell fragments called platelets [12] that are involved in clotting. By volume, the red blood cells constitute about 45% of whole blood, the plasma about 54.3%, and white cells about 0.7%.
The hydrogensulfate ion (HSO − 4), also called the bisulfate ion, is the conjugate base of sulfuric acid (H 2 SO 4). [59] [b] Sulfuric acid is classified as a strong acid; in aqueous solutions it ionizes completely to form hydronium (H 3 O +) and hydrogensulfate (HSO − 4) ions.
Hemoglobin is an iron-containing protein that gives red blood cells their color and facilitates transportation of oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs to be exhaled. [3] Red blood cells are the most abundant cell in the blood, accounting for about 40–45% of its volume. Red blood cells are circular ...
