Amino acids are generally soluble in water and insoluble in non-polar organic solvents such as hydrocarbons. This again reflects the presence of the zwitterions. In water, the ionic attractions between the ions in the solid amino acid are replaced by strong attractions between polar water molecules and the zwitterions.hey are compounds containing an amino group, -NH2, and a carboxylic acid group, -COOH. The biologically important amino acids have the amino group attached to the carbon atom next door to the-COOH group. They are known as 2-amino acids. They are also known (slightly confusingly) as alpha-amino acids.
Common wrist/forearm problems include tendinitis of the muscles that extend your wrist, (bend wrist back). The technical name for this is lateral epicondylitis, also known as tennis elbow. You donât have to play tennis to get tennis elbow. Lateral epicondylitis (tennis elbow) can cause wrist/ forearm or hand pain.
Your forearm is made up of two bones, the radius and ulna. In most cases of adult forearm fractures, both bones are broken. Fractures of the forearm can occur near the wrist at the farthest (distal) end of the bone, in the middle of the forearm, or near the elbow at the top (proximal) end of the bone. This article focuses on fractures that occur in the middle segments of the radius and ulna.
