- n. Any of a group of organic compounds that includes sugars, starches, celluloses, and gums and serves as a major energy source in the diet of animals. These compounds are produced by photosynthetic plants and contain only carbon, hydrogen, and oxygen, usually in the ratio 1:2:1.

- n. One of a group of compounds including the sugars, starches, and gums, which contain six (or some multiple of six) carbon atoms, united with a variable number of hydrogen and oxygen atoms, but with the two latter always in proportion as to form water; as dextrose, C6H12O6.
from The Century Dictionary and Cyclopedia
- n. A general name for a group of organic bodies containing 6 carbon atoms or some multiple of 6, and hydrogen and oxygen in the proportion in which they form water (H2O), that is, twice as many hydrogen as oxygen atoms, as starch, sugar, and cellulose. Also carbhydrate.

While the facts just brought out have much to do with food economy, they are of interest here chiefly because they help to make clear the term carbohydrate, which, as will be admitted, is the only correct name for the food substance it represents.
The other three elements, carbon, hydrogen, and oxygen, go to make up the carbohydrates; in fact, it is from the names of these three elements that the term carbohydrate is derived.
And this is where the name carbohydrate comes from - "carbo" represents the carbon atoms, while the oxygen and hydrogen atoms represent water, or "hydrates".
Haworth did outstanding work in carbohydrate chemistry, establishing the ring structure of glucose.
Eating a great deal of carbohydrate is not good for the subset of the population with inherited insulin resistance, because it tends to make the condition worse.
MAF controls the production of insulin, glucagon and glucagon-like peptides, which play a role both in carbohydrate metabolism as well as food intake.
There are also individual alterations in carbohydrate, protein, and fat metabolism.
Cutting carbs from your diet may have short-term weight loss benefits due to water loss from a decrease in carbohydrate stores, but eating carbs in moderation does not directly lead to weight gain.
What is commonly called carbohydrate addiction should probably be relabeled as calorie addiction,” she added.
A lot of the body's stored carbohydrate is burned while sleeping, and that's energy the brain needs to have a productive morning.
