The term removed refers to the number of generations separating the cousins themselves. So your first cousin once removed is the child (or parent) of your first cousin. Your second cousin once removed is the child (or parent) of your second cousin. And your first cousin twice removed is the grandchild (or grandparent) of your first cousin. Clearly, it doesn't take many generations before your family tree is a bit unwieldy.
A molecule can have more than one acyl halide functional group. For example, adipoyl dichloride, usually simply called adipoyl chloride, has two acyl chloride functional groups; see the structure at right.It is the dichloride (i.e., double chloride) of the 6-carbon dicarboxylic acid adipic acid.n acyl halide (also known as an acid halide) is a chemical compound derived from an oxoacid by replacing a hydroxyl group with a halide group. If the acid is a carboxylic acid, the compound contains a âCOX functional group, which consists of a carbonyl group singly bonded to a halogen atom.
Chloride is the predominant anion that exists in the extracellular space. It maintains cellular integrity via its effects on osmotic pressure and water balance, in addition to maintaining acid-base balance.Chloride daily requirements for adults are 80-120 mEq/d as NaCL. The reference range for chloride is as follows: Normal range: 98-106 mmol/L.
