PL or P/L: parts list: A list, usually tabular and often on the drawing (if not accompanying the drawing on a separate sheet), listing the parts needed in an assembly, including subparts, standard parts, and hardware. There is no consistently enforced distinction between an L/M, a BoM, or a P/L. PLM: product lifecycle management; plant ...
There are three common naming conventions for specifying one of the two enantiomers (the absolute configuration) of a given chiral molecule: the R/S system is based on the geometry of the molecule; the (+)- and (−)- system (also written using the obsolete equivalents d- and l-) is based on its optical rotation properties; and the D/L system is based on the molecule's relationship to ...
Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose. The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form. Glucose is naturally occurring and is found in its free state in fruits and other parts of plants.
Interchangeable parts. Ford would often use interchangeable parts between car models to save costs, but slowly decreased after it lost market share to Chevrolet. Interchangeable parts are parts ( components) that are identical for practical purposes. They are made to specifications that ensure that they are so nearly identical that they will ...

[16][better source needed]It was released as a CD single, cassetteand 7-inchon DGC Records, with alternate track listings for each pressing. Upon its release in Europe, three CD ...
Arginine is the amino acid with the formula (H 2 N)(HN)CN(H)(CH 2) 3 CH(NH 2)CO 2 H. The molecule features a guanidino group appended to a standard amino acid framework. At physiological pH, the carboxylic acid is deprotonated (−CO 2 −) and both the amino and guanidino groups are protonated, resulting in a cation.
Threose is a four-carbon monosaccharide with molecular formula C 4 H 8 O 4. It has a terminal aldehyde group rather than a ketone in its linear chain, and so is considered part of the aldose family of monosaccharides. The threose name can be used to refer to both the D - and L - stereoisomers, and more generally to the racemic mixture ( D / L ...
Chainset: see Crankset. Chainstay: a pair of tubes on a bicycle frame that runs from the bottom bracket to the rear fork ends. Chain tensioner: a device to maintain proper chain tension. Chaintug: a device to aid in setting the proper chain tension. Cluster: a bicycle cogset, either a freewheel, or cassette.
