Nucleic acid other biological data made available through the NCBI web site. Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms. The DNA segments carrying this genetic information are called genes. Likewise, other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information. Along with RNA and proteins, DNA is one of the three major macromolecules that are essential for all known forms of life. DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate
Vaccenic acid acid in osteoblasts. Oxidation of omega-7 unsaturated fatty acids on the skin surface, such as palmitoleic acid and vaccenic acid, may be the cause of the phenomenon commonly known as old person smell. Vaccenic acid Vaccenic acid, also known as ("E")-octadec-11-enoic acid is a naturally occurring trans-fatty acid found in the fat of ruminants and in dairy products such as milk, butter, and yogurt. It is also the predominant fatty acid comprising trans fat in human milk. Its IUPAC name is ("E")-11-octadecenoic acid, and its lipid shorthand name is 18:1 "trans"-11. The name was derived from the Latin "vacca" (cow).
