From there, each one has differences. First, proteins are polymers of amino acids, which are organic molecules with an acidic group (carbon/oxygen) at one end of their backbone and an amine (nitrogen) group at the other end.The side chains contain carbon and sometimes oxygen, nitrogen, or sulfur, and some of the side chains are basic.hey are similar to DNA by containing monosaccharide units, but in a polysaccharide these are usually 5 or 6-carbon units and they are strung together in chains of 10 or more sugars. They are different from proteins and DNA by not being acidic (or basic).
Ursa Major is a large constellation in the shape of a Great Bear.It is the highest in the sky in the spring and the lowest in thesky during autumn.
Instead, weâre located in a minor arm of the galaxy. Our local spiral arm is sometimes Orion Arm, or sometimes the Orion Spur. Itâs between the Sagittarius and Perseus Arms of the Milky Way. The image below shows it. Our sun is located the Orion Arm, or Orion Spur, of the Milky Way galaxy.Itâs a minor spiral arm, located between two other arms. Image updated in 2010 by R. Hurt on Wikimedia Commons. Our local Orion Arm of the Milky Way is some 3,500 light years across.Itâs approximately 10,000 light years in length.Our sun, the Earth, and all the other planets in our solar system reside within this Orion Arm. Weâre located close to the inner rim of this spiral arm, about halfway along its length.ur local Orion Arm of the Milky Way is some 3,500 light years across.
