Tartaric acid crystals drawn as if seen through an optical microscope. Naturally occurring form of the acid is dextro tartaric acid or L-(+)-tartaric acid (obsolete name d-tartaric acid). Because it is available naturally, it is cheaper than its enantiomer and the meso isomer. The dextro and levo prefixes are archaic terms. [15]
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 ...
All blood cells are divided into three lineages. [9] Red blood cells, also called erythrocytes, are the oxygen-carrying cells. Erythrocytes are functional and are released into the blood. The number of reticulocytes, immature red blood cells, gives an estimate of the rate of erythropoiesis. Lymphocytes are the cornerstone of the adaptive immune ...
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%.
From racemic acid found in grapes; from Latin racemus, meaning a bunch of grapes. This acid, when naturally produced in grapes, is only the right-handed version of the molecule, better known as tartaric acid. In many Germanic languages racemic acid is called “grape acid” e.g. German traubensäure and Swedish druvsyra.
Since the proteins have acidic and basic regions, they can serve as both proton donors or acceptors in order to maintain a relatively stable intracellular pH. In the case of a phosphate buffer, substantial quantities of weak acid and conjugate weak base (H 2 PO 4 – and HPO 4 2– ) can accept or donate protons accordingly in order to conserve ...
The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.
It describes the appearance of cells, tissues and cellular structures as seen through the microscope after a histological section has been stained with a basic dye. The most common such dye is haematoxylin. The name basophilic refers to the characteristic of these structures to be stained very well by basic dyes. This can be explained by their ...
