Angiotensin-converting enzyme (ACE) inhibitors are drugs that block the formation of angiotensin II in the kidney, leading to relaxation of the arteries.
These antihypertensive drugs actually​  help to manage a variety of conditions including high blood pressure, heart failure, scleroderma and migraines. 
There are many ACE inhibitor drugs, main difference among them is in how the body gets rid of them afterwards: some are eliminated primarily by the kidneys while others are also eliminated in bile and feces. Except for captopril (Capoten) and lisinopril (Prinivil, Zestril), ACE inhibitors are inactive until they are converted to an active form in the body

juicy and soft cherry-like fruit with a pleasant, tart flavor. Grows on a tropical shrub/small tree in the family Malpighiaceae. Common names include Acerola , Barbados cherry, West Indian cherry and wild crepe myrtle.Acerolla is known for being extremely rich in vitamin C, but it also contains vitamins A, B1, B2, and B3, and antioxidants carotenoids and bioflavonoids. 
Acerola berries could possibly boost immune system and metabolism, be a remedy for diarrhea, anemia, diabetes, dysentery, fever, heart function. Cross-allergies with latex.

Calorie-free sugar substitute (artificial sweeetener), potassium salt of 6-methyl-1,2,3-oxathiazine-4(3H)-one 2,2-dioxide. Also known as E950, acesulfame K, Ace K, Sunett and Sweet One, Acesulfame potassium is as sweet as aspartame, 180-200 times sweeter than sucrose, half as sweet as saccharin (that also has a slightly bitter aftertaste), and only a quarter as sweet as sucralose.
Acceptable daily intake is 15 mg/kg body weight.

organic acid which gives vinegar its sour taste and pungent smell. Produced by acetic acid bacteria including Clostridium acetobutylicum and Acetobacter, found universally in food, water and soil, produced in food spoilage and in the human body - for example, in vaginal lubrication.  This  second simplest carboxylic acid (after formic acid) is an important chemical reagent and industrial chemical, mainly used in the production of cellulose acetate for photographic film and polyvinyl acetate for wood glue, as well as synthetic fibers and fabrics. the acid that gives vinegar its characteristic taste. 
One of short chain fatty acids (SCFAs, also called volatile fatty acids) containing fewer than 6 carbons: Formic acid (C1), acetic acid (C2), propionic acid (C3), butyric acid (C4), and valeric acid (C5). The gut microbial metabolites SCFAs profoundly regulate T cell differentiation in the body, boosting immune system.

if raised, suggests bacterial fermentation due to excess carbohydrate reaching the colon; levels are not significantly altered in patients with malignancy or diabetes mellitus, but severe liver disease and severe acidosis were both associated with increased acetate concentrations. Elevated blood acetate is also an indicator of fast ethanol elimination in chronic alcoholics.

Acetobacter is bacteria converting alcohol to acetic acid and oxidizing lactate and acetate into carbon dioxide and water. 
It is used in the commercial production of vinegar, as fermentation starter cultures, and is found in gut microbiomes of some living organisms. 

Acetobacter aceti bacteria are a widespread group of gram-negative, obligate aerobic rods which oxidize ethanol (alcohol) into ethanoic (acetic) acid. They occur mainly in sugary, acidic and/or alcoholic surroundings and play a positive, neutral, or detrimental roles in food and beverages. It can be found in mangoes, bananas, sugar cane, sweet potato, coffee, cameroon grass, ragi, tea, pineapple, and mealy bugs. 

simplest aromatic ketone, in small amounts can be found in apple, apricots, cheese, chicory, banana, beef, and cauliflower. It is a precursor to useful resins and fragrances, is used in chewing gum and is an  ingredient in fragrances that resemble smell of almond, cherry, honeysuckle, jasmine, and strawberry. 
In humans, acetophenone is metabolized to benzoic acid, carbonic acid, and acetone, but it can be also excreted in its original form in feces and saliva.
Deuterated acetophenone smells fruitier than ordinary acetophenone. It also smells slightly of bitter almonds, just like many compounds containing the cyanide or nitrile group (C≡N) - as both C–D and C≡N bonds vibrate at the same frequency (about 2200 cm-1).   See also 2-aminoacetophenone
