Formic acid is known to be the simplest carboxylic acid‚ and it is an important factor in chemical synthesis and occurs naturally. The chemical formula for Formic Acid is CH202‚ and is mostly found in the venom of bee and ant stings. Formic acid is clear and colorless with a pungent odor. Formic acid is used in many ways; Formic acid is used to preserve livestock. It is also sprayed on animal food and fresh hay to reduce the decay rate. It can also be used as a pesticide to protect bee

Amino Acids Glycine is the smallest of the amino acids. It is ambivalent‚ meaning that it can be inside or outside of the protein molecule. In aqueous solution at or near neutral pH‚ glycine will exist predominantly as the zwitterion. Alanine is a hydrophobic molecule. It is ambivalent‚ meaning that it can be inside or outside of the protein molecule. The α carbon of alanine is optically active; in proteins‚ only the L-isomer is found. Serine differs from alanine in that one of the methylenic
