For many drugs, metabolism occurs in 2 phases. Phase I reactions involve formation of a new or modified functional group or cleavage (oxidation, reduction, hydrolysis); these reactions are nonsynthetic.
Use a capital letter for the first letter in the name when a noun is part of a name such as Calhoun High School. Use a capital letter in the case of a proper noun and in words that come from that proper noun. Examples: Texas and Texan. Use capital letters when naming religions, gods and any language.
I believe that the capitalization of a title depends on the medium. In a formal medium such as an academic paper, the first word and all words other than articles (a, the, etc.) and prepositions (of, under, about, etc.) should be capitalized. However, in more casual situations (such as web logs and Q&A sites), only the first letter must be capitalized.
