Amino acids are joined together in long chains called ❌.

The bonds that join amino acids together are called ❌.

❌ – 2 amino acids joined together
❌ – 3 amino acids joined together
❌ – many amino acids joined together (most common)

❌ protein is very water soluble and ❌ denatured. They are found in ❌, cells, enzymes, and hormones.

❌ proteins are not water soluble and ❌ denatured. They are characterized by high mechanical strength. They are found in ❌.

Number the steps in the nitrogen cycle.

1 Plants obtain nitrogen from air and ❌
2 ❌
3 Humans and animals eat plants and obtain ❌
4 Nitrogen is ❌5 The poopoo is returned to ❌ and the cycle continues

❌ - Basic unit of a protein
❌ - Application of heat, light, or acid to a protein
❌ - Very water soluble and easily denatured
❌ - Not water soluble and not easily denatured
❌ - Needed in diet
❌ - created by the body if nitrogen is available
❌ - In times of stress and/or growth and maturation, they become essential to the body
❌ - transfer of nitrogen to another substance to create a non-essential amino acid
❌ - contain all of the essential amino acids in the correct proportion to support live and growth

❌ - a group of substances related, actually, or potentially to a fatty acid
❌ - lipids added to foods
❌ - fats that are found in foods
❌ - most common fat in our diet. 3 fatty acids attached to glycerol.
❌ - triglycerides that have a hydrogen attached to every available carbon in a fatty acid
❌ - triglycerides that have less than the maximum number of hydrogens attached to the carbons in the fatty acid
❌ - have 1 double bond
❌ - have two or more double bonds
❌ - 1 fatty acid attached to glycerol.
❌ - 2 fatty acids attached to glycerol
❌ - unsaturated fatty acids that have hydrogen atoms added during processing
❌ - the double bonds in unsaturated fats react with oxygen in the air and causes them to spoil
❌ - must be supplied in the diet. polyunsaturated fatty acids
❌ - chemically altered substances that are made to resemble fat

Select the category of triglycerides that this item belongs to
Coconut oil - ❌

❌ - leading cause of death in the U.S.

❌ - hardening of the arteries

❌ - blocked arteries in the heart

❌ - damage to heart from blocked arteries

❌ - blocked arteries in the brain

❌ – contain all of the essential amino acids in the correct proportion to support life and growth. Examples: Animal protein from meats or dairy products

❌ – missing or have a limited supply of essential amino acids. Can support maintenance of body tissues, but will not support growth. Examples: Plant protein from grains and vegetables

❌ – combination of 2 plant proteins with different limiting amino acids. This provides the body with all the essential amino acids needed to sustain life and growth. Example: Butter and bread. Cereal and milk.

❌ – removal of amino groups (NH2) from amino acids. The rest of the amino acid is used for energy (ATP), and/or stored as fat.
❌– combination of two amino groups (NH2 +NH2). Excreted in urine.
❌ – inadequate calorie intake causes protein deficiency.
