All everyday objects that can be touched are ultimately composed of atoms, which are made up of interacting subatomic particles, and in everyday as well as scientific usage, "matter" generally includes atoms and anything made up of them, and any particles and objects that act as if they have both rest mass and volume. However it does not include massless particles such as photons, or other energy phenomena or waves such as light or sound.
Matter exists in various states known as phases that are defined by various physical properties, such as state of matter, phase, shape, and density.
The Standard Model of particle physics and the general theory of relativity describe fundamental particles and the fundamental forces acting between them that control the structure and dynamics of matter.

Karli S. A left directed hydroxyl group the mirror image then represented the L-family. Fischer's initial assignment of the D-configuration had a chance of being right, but all his subsequent conclusions concerning the relative configurations of various aldoses were soundly based.
It is important to recognize that the sign of a compound's specific rotation an experimental number does not correlate with its configuration D or L. It is a simple matter to measure an optical rotation with a polarimeter.
Determining an absolute configuration usually requires chemical interconversion with known compounds by stereospecific reaction paths.
Steven Farmer Sonoma State University. Objectives After completing this section, you should be able to draw the structures of all possible aldotetroses, aldopentoses, and aldohexoses, without necessarily being able to assign names to the individual compounds.
