Biology Symbols

The vector stencils library "Carbohydrate metabolism" contains 25 icons of metabolite symbols.
Use these shapes for drawing carbohydrate metabolism schematics, biochemical diagrams and metabolic pathways maps.
"Carbohydrates are a superior short-term fuel for organisms because they are simpler to metabolize than fats or those amino acids (components of proteins) that can be used for fuel. In animals, the most important carbohydrate is glucose. The concentration of glucose in the blood is used as the main control for the central metabolic hormone, insulin. Starch, and cellulose in a few organisms (e.g., some animals ... and ... microorganisms), both being glucose polymers, are disassembled during digestion and absorbed as glucose. Some simple carbohydrates have their own enzymatic oxidation pathways, as do only a few of the more complex carbohydrates. The disaccharide lactose, for instance, requires the enzyme lactase to be broken into its monosaccharides components; many animals lack this enzyme in adulthood." [Carbohydrate metabolism. Wikipedia]

"Carbohydrate catabolism is the breakdown of carbohydrates into smaller units. Carbohydrates literally undergo combustion to retrieve the large amounts of energy in their bonds. Energy is secured by mitochondria in the form of ATP.
There are several different types of carbohydrates: polysaccharides (e.g., starch, amylopectin, glycogen, cellulose), monosaccharides (e.g., glucose, galactose, fructose, ribose) and the disaccharides (e.g., maltose, lactose).
Glucose reacts with oxygen in the following redox reaction, C6H12O6 + 6O2 → 6CO2 + 6H2O, the carbon dioxide and water is a waste product and the chemical reaction is exothermic.
The breakdown of glucose into energy in the form of molecules of ATP is therefore one of the most important biochemical pathways found in living organisms." [Carbohydrate catabolism. Wikipedia]

The vector stencils library "Citric acid cycle (TCA cycle)" contains 26 symbols of metabolites for drawing metabolic pathway maps and biochemical shematic diagrams of the citric acid cycle (TCA cycle, tricarboxylic acid cycle, Krebs cycle) and diagrams of metabolism processes.
"The citric acid cycle - also known as the tricarboxylic acid cycle (TCA cycle), or the Krebs cycle, - is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats and proteins into carbon dioxide and chemical energy in the form of adenosine triphosphate (ATP). In addition, the cycle provides precursors of certain amino acids as well as the reducing agent NADH that is used in numerous other biochemical reactions. Its central importance to many biochemical pathways suggests that it was one of the earliest established components of cellular metabolism and may have originated abiogenically.
The name of this metabolic pathway is derived from citric acid (a type of tricarboxylic acid) that is consumed and then regenerated by this sequence of reactions to complete the cycle. In addition, the cycle consumes acetate (in the form of acetyl-CoA) and water, reduces NAD+ to NADH, and produces carbon dioxide as a waste byproduct. The NADH generated by the TCA cycle is fed into the oxidative phosphorylation (electron transport) pathway. The net result of these two closely linked pathways is the oxidation of nutrients to produce usable chemical energy in the form of ATP." [Citric acid cycle. Wikipedia]
