No it is not a lipid. Insulin is made up of proteins. It cannot be injected orally.

Hormones vary widely in their structure and make up - therefore it is not appropriate to suggest a monomer of a hormone as there are many many different types.
The simplist hormone are derivatives of the amino acids tyrosine and tryptophan such as the catecholamines (e.g. adrenaline and thyroxine) but as these do not link together into chains.

Well adrenaline is basically a natural drug that gets produced in your body, Now if you are doing a sport and adrenaline kicks in, I would think it not only would you get extremely into the sport you are playing but it would also make you perform much better and focus much better.

Yes, thickening of the uterine lining is one of the main functions of progesterone during the menstrual cycle, allowing the womb to build-up the uterine lining to support a fertilised egg. If pregnancy doesn't occur then it's the drop in progesterone that causes the uterine lining to break down.

Other hormones - hormones that stimulate the secretion of other hormones from endocrine glands are called tropic hormones. An example of this would be the secretion of human gonadotropin releasing hormone (GnRH) by the hypothalamus. This hormone stimulates the anterior pituitary to secrete follicle stimulating hormone (F SH) and luteurizing hormone (LH), two hormones particularly important in menstruation.
Nerve impulse conduction - when a nerve impulse reaches the end of the nerve axon, neurotransmitters are released. In many cases, these neurotransmitters can act as endocrine hormones. For example, in order to stimulate muscle contraction, a nerve impulse that reaches the axon of a nerve that directly contacts a muscle (i.e. a motor neuron), will stimulate the release of acetylcholine. The acetylcholine binds receptors on the muscle and it contracts.
Changes in concentration of extracellular ions or nutrients - many cells have molecules that can act as sensors of the extracellular environment, and changes in this environment can stimulate them to secrete hormones. A common example of this is the secretion of insulin or glucagon. If glucose concentration in the blood is high, insulin is secretes. If blood glucose is low, glucagon is secreted.
In addition, many hormones can be secreted in response to environmental stimuli like a change in heat or light. Often times this secretion is indirect and utilizes one of the previous mentioned mechanisms. However one example of a direct affect of the environment is the hormone melatonin. Melatonin helps regulate sleep/wake cycles and is produced by the pineal gland when directly stimulated by darkness (i.e. night)

Women are born with all the eggs they will ever have. The ovary stores them and at intervals will stimulate and egg to develop.

Orexin has a key function in human neurology and physiology. It is a regulator in and around the hypothalamus which affects one's hunger, fatigue and general arousal. Though its quantity in our anatomy is far less than that of of other neurotransmitters, its role is no less important.

the effects are similar. Both hormones are Na+/H2O regulators in the kidneys, they just perform this function in different ways. ADH contros the H2O in our bodies and how much is released while aldosterone is in control of what is reabsorded.
