Understanding Search Engine Results

In the search marketing field, the pages the engines return to fulfill a query are referred to as search engine results pages (SERPs). Each engine returns results in a slightly different format and will include vertical search results (specific content targeted to a query based on certain triggers in the query, which we will illustrate shortly).

Academics can research current articles in their field.

Glycine is the amino acid that has a single hydrogen atom as its side chain.
  1. The simplest amino acid is glycine (gly).
  2. It consists of two carbon atoms covalently bonded to each other.
  3. To one carbon atom, two oxygen atoms are bonded; to the other carbon atom, an amino group (NH3 +) and 2 hydrogen atoms are bonded.
  4. The carbon that is directly attached to the CO2 - is called the α-carbon.
  5. It is this carbon that makes all amino acids used by man the α -amino acids.
  6. Gly is typically found in proteins where there are turns in the amino acid sequence, as it is very small and has a small "R" group (a hydrogen).
  7. R groups are radical groups, representative groups or reactive groups.
  8. In this case, and for the case of all the amino acids, we will use the second definition of R group to mean the rest of the amino acid molecule beyond the 2d carbon in the back bone of the amino acid.
  9. Gly is an amino acid with an uncharged polar R group.
