Out here in the stroma, a bunch of different enzymes use the carbon dioxide molecules and hydrogen ions made during the light dependent phase to assemble sugar fragments which are half of a glucose molecule (just 3 carbon atoms, instead of the 6 required to make a complete glucose molecule).
An alkane, by definition, only has single bonds. Even if your second diagram made sense (it doesn't for the reason above) it would not be an alkane at all because there is a double bond. Alkanes are a functional group. It's called alkil. As a functional group they have the generic formula R(CH2)nH.
Hydroxyl Functional Group. In organic chemistry the hydroxyl group is define as the functional group in alcohols also being a part of other organic chemical structure like natural products, drugs, and present in some biochemical structureaâ¬âstructureÃ¢ in sugars and in some amino acids like threonine and. phospholipidsor example, Phosphate group is an example of that functional group in which there is multiple bonds with hetero atom like phosphorus. In phosphate functional group one of the oxygen atoms bonded with phosphorus atom as well as one alkyl group.
