Castor bean fruit Ricinus communis : The spiny, globose seed capsule left dries and splits into 3 sections called carpels center. Each carpel right splits open and forcibly ejects a large seed.
In the related Mexican jumping bean Sebastiana pavoniana , a moth occupies each carpel and feeds on the seed tissue inside.
The many "faces" of castor seeds. Like the faces and fingerprints of people, the beautiful designs on castor seeds exhibit infinite genetic variation. The small structure on the end of each seed is a caruncle. The seeds superficially resemble the bodies of ticks, particularly ticks engorged with blood.

Polymers of linoleic acid: The trans and cis configurations of C 18 H 32 O 2 In the trans configuration, the four hydrogen atoms adjacent to the double bonds occur on alternate sides of the main carbon axis two on one side and two on the opposite side.
The trans configuration is chemically more stable. It is typically produced during partial hydrogenation of polyunsaturated vegetable oils. In the cis configuration, all four hydrogen atoms adjacent to the double bonds occur on the same side of the carbon axis. Blood Triglycerides and Cholesterol Cholesterol is a complex lipid and vital precursor of sex hormones, vitamin D and bile salts.
It is produced by the body, although some dietary cholesterol comes from animal products. Cholesterol is carried to sites in the body by low-density lipoprotein molecules LDLs.
High-density lipoproteins HDLs remove cholesterol from these sites and deliver it to the liver for breakdown. Excessive levels of cholesterol in the blood can lead to fatty deposition in blood vessels arteries called plaque.

Some bee experts report it arises from extrafloral nectaries located at the base of the leaves. In addition, there are also nectaries on the leaf stalks and stems as well. Bees also appear to collect nectar from the young seed pods. This is described as being liquid early in the morning and tending to harden as the day progresses, which is often the case with some sources of honeydew.
Easy to grow from seed, castor bean is most widely cultivated in tropical regions. This sun loving species generally needs a growing season of 90 to days, according to the variety.

For poor soils, an additional application of fertilizer during mid-Summer is helpful. Taller varieties of castor beans sometimes benefit from staking for they can blow over in areas that are particularly windy.
Since these plants are known to naturalize, beekeepers can prevent this by removing the seed pods before they split. Remove these from the plant, and discard them in the household trash rather than in the compost bin. A number of castor bean varieties are listed in seed catalogs, such as those of Baker Creek, Select Seeds, J. Some varieties that are available include the following.
