Question: What alcohol is present in both, Monkey Gland and Breakfast martini?

Context paragraphs:
Dufour's gland: Dufour's gland is an abdominal gland of certain insects, part of the anatomy of the ovipositor or sting apparatus in female members of Apocrita.  The diversification of Hymenoptera took place in the Cretaceous and the gland may have developed at about this time (200 million years ago) as it is present in all three groups of Apocrita, the wasps, bees and ants.

Thyroid ima artery: The thyroid ima artery (thyroidea ima artery, arteria thyroidea ima, thyroid artery of Neubauer or the lowest thyroid artery) is an artery of the head and neck.  It is an anatomical variant that, when present, supplies blood to the thyroid gland primarily, or the trachea, the parathyroid gland and the thymus gland (as thymica accessoria) in rare cases.  It has also been reported to be a compensatory artery when one or both of the inferior thyroid arteries are absent and in a few cases the only source of blood to the thyroid gland.  It varies in origin, size, blood supply, and termination, and occurs in only 3–10% of the population.  Because of the variations and rarity, it may lead to surgical complications.

Monkey gland: Monkey gland may refer to surgeon Serge Voronoff's technique of grafting monkey testicle tissue on to the testicles of men for purportedly therapeutic purposes.  It may also refer to:

Monkey Gland: The Monkey Gland is a cocktail of gin, orange juice, grenadine and absinthe created in the 1920s by Harry MacElhone, owner of Harry's New York Bar in Paris, France.

Monkey gland sauce: Monkey gland sauce is a restaurant item in South Africa.  The tangy sauce is prepared in several manners, and may include a blend of fruit and spices.  It is typically served with meats, such as steak, hamburgers, pork ribs or chicken.  Several popular South African fast food chains serve a Monkey gland Burger.

Bartholin gland carcinoma: Bartholin gland carcinoma is an uncommon type of malignancy in the Bartholin gland that accounts for 1% of all vulvar malignant neoplasms.  It is most common in women in their mid-60s.  The tumor can become large before a woman is aware of symptoms.  One of the first symptoms can be dyspareunia.  In other instances a woman may find a mass or ulcer in the vulva area.  Many clincians assume that an enlarged Bartholin gland is malignant in postmenopausal woman until proven otherwise.  The growth of the tumor can spread to nearby areas such as the ischiorectal fossa and inguinal lymph nodes.  Approximately 50% of bartholin gland carcinomas originate from squamous cell carcinomas. Another uncommon characteristic of Bartholin gland malignancies is that the growth of a lesion originates from the three types of epithelial tissue present in the gland: mucinous, transitional, and squamous.

Breakfast martini: A breakfast martini is a form of cocktail created by bartender Salvatore Calabrese.  The most famous "marmalade cocktail", it is a gin martini with marmalade, orange liqueur, and lemon juice in place of vermouth.

Intestinal gland: In histology, an intestinal gland (also crypt of Lieberkühn and intestinal crypt) is a gland found in the intestinal epithelium lining of the small intestine and large intestine (colon).  The glands and intestinal villi are covered by epithelium which contains multiple types of cells: enterocytes (absorbing water and electrolytes), goblet cells (secreting mucus), enteroendocrine cells (secreting hormones), cup cells, tuft cells and, at the base of the gland, Paneth cells (secreting anti-microbial peptides) and stem cells.  These cells are not all present in the colon.

Cherry eye: Cherry eye is a disorder of the nictitating membrane (NM), also called the third eyelid, present in the eyes of dogs and cats.  Cherry eye is most often seen in young dogs under the age of two.  Common misnomers include adenitis, hyperplasia, adenoma of the gland of the third eyelid; however, cherry eye is not caused by hyperplasia, neoplasia, or primary inflammation.  In many species, the third eyelid plays an essential role in vision by supplying oxygen and nutrients to the eye via tear production.  Normally, the gland can evert without detachment.  Cherry eye results from a defect in the retinaculum which is responsible for anchoring the gland to the periorbita.  This defect causes the gland to prolapse and protrude from the eye as a red fleshy mass.  Problems arise as sensitive tissue dries out and is subjected to external trauma Exposure of the tissue often results in secondary inflammation, swelling, or infection.  If left untreated, this condition can lead to Keratoconjunctivitis sicca (KCS) and other complications.

Absent adrenal gland: Absent adrenal gland is a rare condition where the adrenal gland is absent at birth.  It should not be confused with adrenal insufficiency or congenital adrenal hyperplasia, where the gland is present but may not be functioning adequately.
