Option A: Human nutrition and health. Define nutrient . A Nutrient is a chemical substance found in foods that is used in the human body. http://www.faqs.org/nutrition/images/nwaz_02_img0168.jpg. List the type of nutrients that are essential in the human diet:.
A Nutrient is a chemical substance found in foods that is used in the human body.
Amino acidsare the building blocks of protein . The body has twenty different amino acids that act as these building blocks.
Nonessential amino acids are those that the body can synthesize for itself, provided there is enough nitrogen, carbon, hydrogen, and oxygen available.
Essential amino acids are those supplied by the diet , since the human body either cannot make them at all or cannot make them in sufficient quantity to meet its needs.
Under normal conditions, eleven of the amino acids are nonessential and nine are essential.
Saturated fatty acids can align closely together so lipids containing primarily saturated fatty acids are usually solid at room temperature (aka Fat).
The C=C double bond(s) in unsaturated fatty acids causes the molecule to "bend" (a fatty acid with one C=C bond is mono-unsaturated, a fatty acid with several C=C bonds is poly-unsaturated.
Because they are "bent", unsaturated fatty acids are less able to interact and lipids contain primarily unsaturated fatty acids are liquid at room temperature (oils).
Cis and trans are terms that refer to the arrangement of chains of carbon atoms across the double bond. In the cis arrangement, the chains are on the same side of the double bond, resulting in a kink. In the trans arrangement, the chains are on opposite sides of the double bond, and the chain is straight.
These foods are all “mineral dense” foods. Find out which minerals are in each food.
A vitamin is an organic compound required as a nutrient in tiny amounts by an organism
This might be a useful table to help you fill in the Minerals lists.
Consists mainly of Cellulose which is insoluble and indigestible by animals. Forms bulk which allows the gut to move the food.
Not enough fibre causes constipation in the short term, and may lead to spastic colon in long term and cancers of the gut due to build up of poisons.
