Question

difference between steroids and carotenoids

Answer 1

HERE IS YOUR ANSWER.....

Carotenoids -

The carotenoids are a family of light-absorbing pigments found in plants and animals. Beta-carotene is one of the pigments that traps light energy in leaves during photosynthesis. In humans, a molecule of beta-carotene can be broken down into two vitamin A molecules, from which we make the pigment rhodopsin, which is required for vision. Carotenoids are responsible for the colors of carrots, tomatoes, pumpkins, egg yolks and butter.

Steroids -

The steroids are a family of organic compounds whose multiple rings share carbons. The steroid cholesterol is an important constituent of membranes. Other steroids function as hormones, chemical signals that carry messages from one part of the body to another. Testosterone and the estrogens are steroid hormones that regulate sexual development in vertebrates. Cortisol and related hormones play many regulatory roles in the digestion of carbohydrates and proteins, in the maintenance of salt balance and water balance and in sexual development. Cholesterol is synthesized in the liver and is the starting material for making testosterone and other steroid hormones, as well as the bile salts that help break down dietary fats so that they can be digested. Cholesterol is absorbed from foods such as milk, butter and animal fats.
