In 1975, the 20-year-old Jobs and Wozniak set up shop in Jobs' parents' garage, dubbed the venture Apple, and began working on the prototype of the Apple I. To generate the $1,350 in capital they used to start Apple, Steve Jobs sold his Volkswagen microbus, and Steve Wozniak sold his Hewlett-Packard calculator.
carboxyl group. in organic chemistry, group of atoms within a molecule that is responsible for certain properties of the molecule and reactions in which it takes part. Organic compounds are frequently classified according to the functional group or groups they contain.
The side groups are what make each amino acid different from the others. Of the 20 side groups used to make proteins, there are two main groups: polar and non-polar. These names refer to the way the side groups, sometimes called R groups, interact with the environment. carboxyl group is made up of one carbon (C) and two oxygen (O) atoms. That carboxyl group has a negative charge, since it is a carboxylic acid (-COOH) that has lost its hydrogen (H) atom. What is left â the carboxyl group â is called a conjugate base. The second carbon is connected to the amino group.
