Neurosecretory cells make and release the hormones from the posterior pituitary. The cell bodies of these neurosecretory cells receive synapses from Afferent neuron and their axon terminals release hormones into blood stream or the local extracellular space.
Neurohormone is generally produced by neurosecretory cells and liberated by nerve impulses. Neurosecretory cells receive synapses from afferent neurons to guide magnocellular neurons .
A synapse is known as a small junction at the end of a neuron that allows any signal to pass through one neuron to another. Synapse is a junction were the one neuron get connected with the other neuron .

The inside of the barrel-shaped LDL protein consists of hydrophobic amino acids, while its outside portions in contact with the blood fluid consist of hydrophilic amino acids.
LDL is a type of lipoprotein, i.e., it contains protein as well as lipid (cholesterol). The full form of LDL is Low Density Lipid. LDL is considered to be the bad cholesterol for the body. It can cause diseases of the heart like heart attack or stroke.
Amino acids are the essential molecule that act as a monomer for the formation of proteins inside the body. They contain an amino group and a carboxylic group attached to the same carbon atom. There are also a hydrogen atom and a variable R group attached to the carbon, also called the alpha carbon.

Natural selection is a type of evolution that allows organisms to adapt into the environment they're in for survival.
Answer:
a. The molecule is not lipid soluble b. The molecule is not derived from a series of steps beginning with cholesterol
Explanation:
All the steroid hormones have a four ring sterol nucleus in their structure. These hormones are soluble in lipids. Steroid hormones are produced by the pathways using cholesterol as the starting substance. Some of the examples of steroid hormones are aldosterone, calcitriol, estrogens, and progesterone. Therefore, if the given molecule is not soluble in lipids and is not derived from cholesterol, it cannot be a steroid hormone.
