"Most carrot cultivars are about 88% water, 7% sugar, 1% protein, 1% fibre, 1% ash, and 0.2% fat. The fibre comprises mostly cellulose, with smaller proportions of hemicellulose and lignin. Carrots contain almost no starch. Free sugars in carrot include sucrose, glucose, xylose and fructose. Nitrite and nitrate contents are about 40 and 0.41 milligrams per 100 grams (fresh), respectively. Most of the taste of the vegetable is due to glutamic acid and other free amino acids. Other acids present in trace amounts include succinic acid, α-ketoglutaric acid, lactic acid and glycolic acid; the major phenolic acid is caffeic acid.
The carrot gets its characteristic and bright orange colour from β-carotene, and lesser amounts of α-carotene and γ-carotene. α and β-carotenes are partly metabolised into vitamin A in humans. β-carotene is the predominant carotenoid, although there are lesser amounts of α-carotene and γ-carotene. There are typically between 6000 and 54,000 micrograms of carotenoids per 100 grams of carrot root. Massive overconsumption of carrots can cause carotenosis, a benign condition in which the skin turns orange. Carrots are also rich in antioxidants and minerals.
Carrots are useful companion plants for gardeners. There is experimental evidence that growing it intercropped with tomatoes increases tomato production. If left to flower, it (like any umbellifer) attracts predatory wasps that kill many garden pests.
Carrots grow best in full sun but tolerate some shade. In order to avoid growing deformed carrots it is better to plant them in loose soil free from rocks. They thrive in raised garden beds. High nitrogen levels should be avoided, as this will cause the vegetables to become hairy and misshapen."
