"' Limonene "'is a colorless liquid hydrocarbon classified as a cyclic terpene . 35. It is a viscous liquid composed mainly of volatile terpenes and is produced mostly by coniferous trees. 36. Enzymatic analogs from terpene biosynthesis which help rationalize the above proposed numbered biosynthetic steps are as follows: 37. Studies suggest that terpenes keep cholesterol crystals from forming in bile and may even dissolve existing stones. 38. Silphium plants contain terpenes and have a turpentinelike smell, but the mixtures of terpenes differ between species. 39. Silphium plants contain terpenes and have a turpentinelike smell, but the mixtures of terpenes differ between species. 40. He was responsible for naming terpene and pinene, and for undertaking the first systematic study of pinene.
